Is there a way to find out the assembly name at design-time (i.e. not using reflection or runtime APIs such as System.Reflection.Assembly.GetEntryAssembly) from within Visual Studio?
The scenario requires a tool to get the assembly name that a Visual Studio project will eventually compile into.
This is like parsing the AssemblyName property of the .csproj - I am wondering if there are any APIs that can give this information reliably.
Please do not respond back with runtime APIs that use reflection - there is no assembly file present at the time I need the assembly name - just the metadata of the assembly in the csproj file.
if you are calling the tool via a post/pre-build event, this data is very easy to access.
Just go to the "project properties->Build Events" tab, then select either "edit pre-build" or "edit post-build", depending on when you want the tool to run. This should bring up an edit window with the ever helpful "Macros >>" button. Press this and you will be given a heap of macros to use and should be pretty much everything you need.
The "API" you could use is LINQ to XML after all the .csproj file is just xml. (and you can get the location of the .csproj file if you need from the solution file which for some reason is not XML but can be easily parsed)
You can use "TargetName" available in Macros for Post-build events. It will give you the assembly name for your project.
After a quick run through MSDN I found this article which might be a good start for some further research:
Accessing Project Type Specific Project, Project Item, and Configuration Properties
I think you will need to write some regular expression that will give you the value of "AssemblyTitle" attribute in AssemblyInfo.cs file.
Something like this:
public class Assembly
{
public static string GetTitle (string fileFullName) {
var contents = File.ReadAllText (fileFullName); //may raise exception if file doesn't exist
//regex string is: AssemblyTitle\x20*\(\x20*"(?<Title>.*)"\x20*\)
//loading from settings because it is annoying to type it in editor
var reg = new Regex (Settings.Default.Expression);
var match = reg.Match (contents);
var titleGroup = match.Groups["Title"];
return (match.Success && titleGroup.Success) ? titleGroup.Value : String.Empty;
}
}

I have a web application project. I generated the DLL and import it in another project. I implemented VirtualPathProvider.
I followed this web site: http://support.microsoft.com/kb/910441/en-us?spid=8940&sid=global, and everything works until I add another site master.
I added site_export.master and changed its Build Action to Embedded Resource.
I changed my page to use the new site master.
GetManifestResourceStream() returns null when I load site_export.master.
I call GetManifestResourceNames() to check if site_export.master exists in the DLL and it does. It's in the list. All of the name spaces match. I didn't list the name space out here.
Why can't GetManifestResourceStream() load my new site_export.master? It loads site.master just fine. I know my DLL is loaded because I can see other files in the DLL.
Remember the following issues...
Step 1. Build action set to embedded resource see
C#’s GetManifestResourceStream Gotcha
Step 2. Use namespace.resourcename see GetManifestResourceStream() returns null ?
Actually, this method returns null if a private resource in another assembly is accessed and the caller does not have ReflectionPermission with the ReflectionPermissionFlag.MemberAccess flag.
Side-hint. To make sure you're in the right assembly and with right name: dump and evaluate all the resources available in your target assembly
string[] names = assembly.GetManifestResourceNames();
(in my case, I misused a namespace from another assembly)
I did this to make it work:
Step 1: Select the resource (CRDF.xsl in my case) and right click > Properties.
Set Build Action to "EmbeddedResource" and Logical Name to name of your choice, e.g. CRDFXSL.
Step 2 : Change your Source code like this:
Assembly _assembly;
_assembly = Assembly.GetExecutingAssembly();
xslStream = _assembly.GetManifestResourceStream("CRDFXSL");
_xmlReader = XmlReader.Create(xslStream);
Thus everything went smoooooooth..
Hint and Caution:
If the "Assembly name" and "Default namespace" does not match in the project file then also GetManifestResourceStream would return null. GetManifestResourceNames still returns the names of assemblies but during loading the manifest would not work.
Try this:
Dim ctx As Windows.ApplicationModel.Resources.Core.ResourceContext = New Windows.ApplicationModel.Resources.Core.ResourceContext()
ctx.Languages = {Globalization.CultureInfo.CurrentUICulture.Name}
Dim rmap As Windows.ApplicationModel.Resources.Core.ResourceMap = Windows.ApplicationModel.Resources.Core.ResourceManager.Current.MainResourceMap
Dim res = rmap.GetValue("Assets/sample.png", ctx)
Dim resFile = Await res.GetValueAsFileAsync
The Windows.ApplicationModel.Resources.Core.ResourceManager.Current.MainResourceMap list all resources.
You have a large Visual Studio Solution with dozens of project files in it. How would you verify that all the projects follow certain rules in their property settings, and enforce these rules if a new project is added. For example check that all projects have:
TargetFrameworkVersion = "v4.5"
Platform = "AnyCPU"
WarningLevel = 4
TreatWarningsAsErrors = true
OutputPath = $(SolutionDir)bin
SignAssembly = true
AssemblyName = $(ProjectFolderName)
I know two methods myself that I will add in an answer below, but I was wondering how people go about doing this type of project test. I'm especially interested to learn about available solutions such as libraries or build tasks for this rather than having to have to invent something new or write it from scratch.
*.sln files are plain text and easily parsable, and *.*proj files are xml.
You can add a dummy project with a prebuild step that parses the sln to retrieve all of the project files, validate their settings, print a report, and fail the build if necessary.
Also, you should check this post to ensure the prebuild step is always executed. Essentially, you specify a blank output in the custom build step to force a rebuild.
The following list identifies the key file types that are automatically added to VSS when a solution is added to source control by using the Visual Studio .NET integrated development environment (IDE):
Solution files (.sln). The key items maintained within these files include a list of constituent projects, dependency information, build configuration details, and source control provider details.
Project files (.csproj or *.vbproj). The key items maintained within these files include assembly build settings, referenced assemblies (by name and path), and a file inventory.
Application configuration files. These are configuration files based on Extensible Markup Language (XML) used to control various aspects of your project's run time behavior.
Use a Single Solution Model Whenever Possible an

AND For CONTINUOUS INTEGRATION :
there are many tools available like MSBuild, Jenkins, Apache's Continuum, Cruise Control (CC), and Hudson(plugin can be extended to c#)
This is what I have myself:
One way to do this is to create an MSBuild target with error conditions:
<Error Condition="'$(TreatWarningsAsErrors)'!='true'" Text="Invalid project setting" />
I like this approach because it is integrated with MSBuild and gives you early errors, however, you have to modify every project to import it in them or get all your team members to use a special command prompt with environment variables that will inject custom pre-build steps into your projects during the build, which is a pain.
The second approach I know is to use some library like VSUnitTest which provides an API to project properties that you can test against. VSUnitTest is currently not open source and unlisted from the NuGet service.
You could write some code to open the the solution as a text file to identify all of the csproj files referenced, in turn opening each of these as xml files, and then writing unit tests to ensure specific nodes of the project match what you expect.
It's a quick and dirty solution, but works for CI and gives you the flexibility to ignore nodes you don't care about. It actually sounds kinda useful. I have a solution with 35 projects I'd like to scan too.
Let's try something completely different: you could ensure that they are consistent by construction by generating them from a template or by using a build generation tool such as CMake. This might be simpler than attempting to make them consistent after the fact.
In our work we use a powershell script that checks project settings and modified them if they are incorrect. For example, we remove Debug configuration this way, disable C++ optimization and SSE2 support. We run it manually, but definitely it is possible to run it automatically, e.g. as pre\post build step.
Below the example:
`function Prepare-Solution {
param (
[string]$SolutionFolder
)
$files = gci -Recurse -Path $SolutionFolder -file *.vcxproj | select - ExpandProperty fullname
$files | %{
$file = $_
[xml]$xml = get-content $file
#Deleting Debug configurations...
$xml.Project.ItemGroup.ProjectConfiguration | ?{$_.Configuration -eq "Debug"} | %{$_.ParentNode.RemoveChild($_)} | Out-Null
$xml.SelectNodes("//*[contains(#Condition,'Debug')]") |%{$_.ParentNode.RemoveChild($_)} | Out-Null
if($xml.Project.ItemDefinitionGroup.ClCompile) {
$xml.Project.ItemDefinitionGroup.ClCompile | %{
#Disable SSE2
if (-not($_.EnableEnhancedInstructionSet)){
$_.AppendChild($xml.CreateElement("EnableEnhancedInstructionSet", $xml.DocumentElement.NamespaceURI)) | Out-Null
}
if($_.ParentNode.Condition.Contains("Win32")){
$_.EnableEnhancedInstructionSet = "StreamingSIMDExtensions"
}
elseif($_.ParentNode.Condition.Contains("x64")) {
$_.EnableEnhancedInstructionSet = "NotSet"
} else {
Write-Host "Neither x86 nor x64 config. Very strange!!"
}
#Disable Optimization
if (-not($_.Optimization)){
$_.AppendChild($xml.CreateElement("Optimization", $xml.DocumentElement.NamespaceURI)) | Out-Null
}
$_.Optimization = "Disabled"
}
}
$xml.Save($file);
} }`
A file is an assembly if and only if it is managed, and contains an assembly entry in its metadata. For more information on assemblies and metadata, see the topic Assembly Manifest.
How to manually determine if a file is an assembly
Start the Ildasm.exe (IL Disassembler).
Load the file you wish to test.
If ILDASM reports that the file is not a portable executable (PE) file, then it is not an assembly. For more information, see the topic How to: View Assembly Contents.
How to programmatically determine if a file is an assembly
Call the GetAssemblyName method, passing the full file path and name of the file you are testing.
If a BadImageFormatException exception is thrown, the file is not an assembly.
This example tests a DLL to see if it is an assembly.
class TestAssembly
{
static void Main()
{
try
{
System.Reflection.AssemblyName testAssembly = System.Reflection.AssemblyName.GetAssemblyName(#"C:\Windows\Microsoft.NET\Framework\v3.5\System.Net.dll");
System.Console.WriteLine("Yes, the file is an assembly.");
}
catch (System.IO.FileNotFoundException)
{
System.Console.WriteLine("The file cannot be found.");
}
catch (System.BadImageFormatException)
{
System.Console.WriteLine("The file is not an assembly.");
}
catch (System.IO.FileLoadException)
{
System.Console.WriteLine("The assembly has already been loaded.");
}
}
}
// Output (with .NET Framework 3.5 installed):
// Yes, the file is an assembly.
Framework is the highest installed version, SP is the service pack for that version.
RegistryKey installed_versions = Registry.LocalMachine.OpenSubKey(#"SOFTWARE\Microsoft\NET Framework Setup\NDP");
string[] version_names = installed_versions.GetSubKeyNames();
//version names start with 'v', eg, 'v3.5' which needs to be trimmed off before conversion
double Framework = Convert.ToDouble(version_names[version_names.Length - 1].Remove(0, 1), CultureInfo.InvariantCulture);
int SP = Convert.ToInt32(installed_versions.OpenSubKey(version_names[version_names.Length - 1]).GetValue("SP", 0));
For .Net 4.5
using System;
using Microsoft.Win32;
...
private static void Get45or451FromRegistry()
{
using (RegistryKey ndpKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32).OpenSubKey("SOFTWARE\\Microsoft\\NET Framework Setup\\NDP\\v4\\Full\\")) {
int releaseKey = Convert.ToInt32(ndpKey.GetValue("Release"));
if (true) {
Console.WriteLine("Version: " + CheckFor45DotVersion(releaseKey));
}
}
}
...
// Checking the version using >= will enable forward compatibility,
// however you should always compile your code on newer versions of
// the framework to ensure your app works the same.
private static string CheckFor45DotVersion(int releaseKey)
{
if (releaseKey >= 393273) {
return "4.6 RC or later";
}
if ((releaseKey >= 379893)) {
return "4.5.2 or later";
}
if ((releaseKey >= 378675)) {
return "4.5.1 or later";
}
if ((releaseKey >= 378389)) {
return "4.5 or later";
}
// This line should never execute. A non-null release key should mean
// that 4.5 or later is installed.
return "No 4.5 or later version detected";
}
For similar purposes we use custom MSBuild fragments with common properties that we want to share between the projects, like this (build.common.props file):
<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="12.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>
<TargetFrameworkVersion>v2.0</TargetFrameworkVersion>
<PlatformToolset>v90</PlatformToolset>
<OutputPath>$(SolutionDir)..\bin\$(PlatformPath)\$(Configuration)\</OutputPath>
<!-- whatever you need here -->
</PropertyGroup>
</Project>
And then we just include this fragment to real VS projects we want to apply these properties to:
<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="12.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>
<CommonProps>$(SolutionDir)..\Build\build.common.props</CommonProps>
</PropertyGroup>
<Import Project="$(CommonProps)" />
<!-- the rest of the project -->
</Project>
We handle a lot of things using this approach:
common properties, as you mentioned
static analysis (FxCop, StyleCop)
digital sign of assemblies
etc.
The only disadvantage that you need to include these MSBuild fragments into each project file, but once you do that, you have all the benefits of modular build system that is easy to manage and update.
You could go the search & replace Regex way with a handwritten C#, Script, powershell or similar. But it has the following problems:
Difficult to read (Read your pretty regex in three or more months)
Difficult to enhance(New regex for new search/replace/check feature)
Easy to break (a new release/format of ms build project or a not forecast tag may not work)
Harder to test (you must check that no unintended match occurs)
Difficult to maintain (because of the above)
and the following advantages:
Not doing any extra validation which (may) let it work on any kind of project (mono or visual).
Doesn't care about \r :)
The best could be to use the Microsoft.Build.Evaluation
and build a C# tool which does all your testing/checking/fix and so on.
I've done a command line tool that use a sourcefile list (used by Mono) and update sources of csproj and another which dumps on console the csproj content. It was easy to do, pretty straightforward and easy to test also.
However, it may fail (as I've experienced it) on projects modified by "non" Ms tool (like Mono Studio) or because of missing \r....
Anyway, you can always handle it with an exception catch and a good message.
Here a sample by using Microsoft.Build.dll (don't use Microsof.Build.Engine as it is obsolete):
using System;
using Microsoft.Build.Evaluation;
internal class Program
{
private static void Main(string[] args)
{
var project = new Project("PathToYourProject.csproj");
Console.WriteLine(project.GetProperty("TargetFrameworkVersion", true, string.Empty));
Console.WriteLine(project.GetProperty("Platform", true, string.Empty));
Console.WriteLine(project.GetProperty("WarningLevel", true, string.Empty));
Console.WriteLine(project.GetProperty("TreatWarningsAsErrors", true, "false"));
Console.WriteLine(project.GetProperty("OutputPath", false, string.Empty));
Console.WriteLine(project.GetProperty("SignAssembly", true, "false"));
Console.WriteLine(project.GetProperty("AssemblyName", false, string.Empty));
Console.ReadLine();
}
}
public static class ProjectExtensions
{
public static string GetProperty(this Project project, string propertyName, bool afterEvaluation, string defaultValue)
{
var property = project.GetProperty(propertyName);
if (property != null)
{
if (afterEvaluation)
return property.EvaluatedValue;
return property.UnevaluatedValue;
}
return defaultValue;
}
}
I also faced this issue and created a small solution that creates a csv file with details to identifies the inconsistences. You can look at it in this url

I'm getting designer error on code:
The Component i'm willing to define a List of properties for:

In the Resx file there is data field with base64 encoded stuff inside when this error is present.
I have been searching for an answer, but the best i got is to restart everything, it didn't help me, do you guys have any suggestions? I'm using .net 4 client and visual studio 2010
In my experience, this is due to a change of version of a referenced library, or a change of the lib itself, which contains the backing type of a property you have defined in your user control. The solution is to "force" the visual studio designer to re-initialize it's designer code for that type, and not expect to retrieve a "canned" version of it from the .resx file of the control.
1) Delete the offending data section in the .resx file of your control. This will be a section in the xml of the .resx file associated with your user control, which has a node: <data></data> - the name attribute will be set to whatever you've named that object in the properties of whatever you added this type to. The <data>/data> section contains a base64 encoded string that is the encoded form of the name and version of the library the type comes from. This is where the problem ism, because it now contains an encoded version of the library and/or version number you are no longer referencing in order to include the type. Delete the entire <data>/data> section, from opening to closing tag, save the change and close the file. Now the "artifact" is gone.
2) Now find the place in the designer file for your control, where the type is instantiated; this is initialization code generated for you by visual studio, and it is the place that is expecting to load a "canned" definition of the type from the base64 encoded string contained within the .resx file. The line will look something like this:
this.myCtrlFoo.MyPropertyFroo = ((MyNamespaceFoo.MyTypeFoo)(resources.GetObject("myCtrlFoo.MyPropertyFroo")));
...now just replace the resources.GetObjec call with the instantiation of a new instance of the appropriate type like so:
this.myCtrlFoo.MyPropertyFroo = ((MyNamespaceFoo.MyTypeFoo)(new MyNamespaceFoo.MyTypeFoo()));
...now save the change to the file, close it, rebuild, and everything should now build & run OK.
Put the MyTreeView and TypeDescriptorBase classes into another project and reference it from your GUI project will resolve the issues.
I'm not sure why exactly the problem occurs - I guess it has something to do with the way the serializing process is generating the base64 string for the DescriptorsAvailable Property. Maybe somebody else can give us some insight.
I've struggled quite a bit with this; I have three user controls that all expose the same non-designer property, but for some reason, any change to two of the three would instantly cause the next build to fail with this same issue. This is in VS 2015.
I wound up having to add the following two attributes to the property that kept expanding in the resx file, and it hasn't occurred since. It works for me because they're not available in the designer anyway.
[Browsable(false)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
For me, this error occured when I used a custom class as a property for the user control. When I switched from property to traditional get- and set- methods, the error disappeared. I guess this is because properties are already compiled at design-time, so when you build the whole project, a new version of the custom class is compiled which is separate from the one of the control, and the reference is broken.
For me, with the custom class Inventory, all I had to do was to switch from this property-based approach:
public Inventory Resources {get;set;}
to this method-based approach:
private Inventory resources;
public Inventory getResources() { return resources; }
public void setResources(Inventory newResources) { resources = newResources; }
I hope this helps someone, as I've been spending some hours on figuring it out.
In my case I've got the error : "error MSB3103: Invalid Resx file. The specified module could not be found" executed in a light windows container based on mcr.microsoft.com/powershell instead of mcr.microsoft.com/windows:1909 (was working fine on 1909).
The error was on a ressource icon that was compressed with PNG inside.
It can be checked by opening the ressource on visual studio : Project > Properties > Ressources.resx, select icons, double click on the icon, check the end of the title that is either "..,BMP]" or "...,PNG]").
Updating the icon with an uncompressed format solve the "Invalid Resx file" issue.
I stumbled across this question today whilst looking for the solution to a similar issue.
Unfortunately none of the above worked for me, however my issue turned out to be that I had different versions of the .NET Framework for different projects. For example;
Project A - .NET Framework 4.7.2
Project B - .NET Framework 4
Where Project B was referencing Project A. Solution was simply to change the .NET Framework version of Project B to 4.7.2 (in my case) and hey presto the issue was resolved.
A shame Visual Studio doesn't provide a more helpful error message in this case, but something to look out for!
I'm trying to extract the version number from a AssemblyInfo.cs file!
And I'm trying to use System.Reflection.Assembly.LoadFile(path); But while doing this I get a BadImageFormatException; "The module was expected to contain an assembly manifest. (Exception from HRESULT: 0x80131018)". So now I wounder, is that not a possible way to go about it? And should I use RegEx instead?
I have read many examples with GetExecutingAssembly() but I do want to get the version from an other project.
Clarification: I want to read the version info from the AssemblyInfo.cs file! And not from a compiled file. I'm trying to make a tool to update my version numbers before I make a new release.
You can get Assembly version without loading it as:
using System.Reflection;
using System.IO;
...
// Get assembly
AssemblyName currentAssembly = AssemblyName.GetAssemblyName(path);
Version assemblyVersion = currentAssembly.Version;
Edit:
If you want to read file then you can do it like this:
string path = #"d:\AssemblyInfo.cs";
if (File.Exists(path))
{
// Open the file to read from.
string[] readText = File.ReadAllLines(path);
var versionInfoLines = readText.Where(t => t.Contains("[assembly: AssemblyVersion"));
foreach (string item in versionInfoLines)
{
string version = item.Substring(item.IndexOf('(') + 2, item.LastIndexOf(')') - item.IndexOf('(') - 3);
//Console.WriteLine(Regex.Replace(version, #"\P{S}", string.Empty));
Console.WriteLine(version);
}
}
//Output
1.0.*
1.0.0.0
Hope this help...
You can specify the target assembly path in AssemblyName.GetAssemblyName
AssemblyName.GetAssemblyName("ProjectB.exe").Version
AssemblyInfo.cs file gets compiled to IL assembly.
If you load that assembly you can read the version with all the examples that you have already seen. Which is reading an embedded version information from a compiled assembly file, and it may be overwritten by compilation process to a value different from what is in AssemblyInfo.cs
However it sounds like what you want instead is to read a version number from AssemblyInfo.cs text file, without compiling it down.
If this is the case you really just have to use regex with a format appropriate for your project, or even come up with a convention that will keep it simple.
This could be as simple as
var versionMatch = Regex.Match(File.ReadAllText(filename), #"AssemblyVersion\s*\(\s*""([0-9\.\*]*?)""\s*\)");
if (versionMatch.Success)
{
Console.WriteLine(versionMatch.Groups[1].Value);
}
You would have to consider convention around what goes there, since 1.0.* is a valid version string that translates to timestamp values of form 1.0.nnn.mmm at compile time, and nnn and mmm part closely guessable but not precisely guessable.
It sounds like you're trying to load an assembly compiled for x86 in an x64 environment or vice-versa.
Ensure the assembly this code resides in is built for the same environment as the target and you can get it with the examples it sounds like you've read.
You can proceed with Assembly.GetName().Version where your assembly could be the type of your class
public class Test
{
public static void Main()
{
Console.WriteLine("Current assembly : " + typeof(Test).Assembly.GetName().Version);
}
}
For the test application I have working on, shows me below details using above code:
I'm making a class library project in C#. How to get the name of the project which will call the method from my class library?
I tried with Reflection:
System.Reflection.Assembly.GetExecutingAssembly()
and with
GetCallingAssembly
but it didn't work.
I am looking for this also. File name I can get from StackFrame just like the answer by #Maheep but to get project name is not really straight forward.
A. I just got a simple solution:
Based on the FileName (path) found from StackFrame, iterate for each parent folder.
Find any file with *.csproj (C#)
Optionally open csproj file to ensure the current file <Compile Include="Folder\File.cs" /> is included
The file name of csproj is the project name
B. I found alternative by using pre-build macro $(ProjectDir) and access the result in code here: What's an easy way to access prebuild macros such as $(SolutionDir) and $(DevEnvDir) from code in C#?
If I understand your question directly, this is not possible to do in code. The only way to do this is with static analysis of the code.
Resharper has this ability - To find out where a particular class/method/property is used, you can right click on the declaration and select "Find Usages". This is a very handy feature :)
But that only works of the code calling your method is known (in the same solution). It wont work when third parties consume your library.
What exactly are you trying to achieve here? If your method needs to identify callers, you should add this as a requirement (ie add a parameter containing the caller identity).
public void MyMethod()
{
// I need name of caller project, but how?
}
public void MyMethod(String callerProject)
{
// People who call this method know the name of their own project :)
}
You will have to use StackTrace Class for this. StackTrace class has GetFrame method which will give you calling method name. This will return MethodBase class object which has property DeclaringType. Using this type information you can get assembly details as well.
private void YouCalledMethod()
{
StackTrace stackTrace = new StackTrace();
StackFrame stackFrame = stackTrace.GetFrame(1);
Assembly assembly = stackFrame.GetMethod().DeclaringType.Assembly;
//use this assembly object for your requirement.
}
Look at this How to print the current Stack Trace in .NET without any exception? question also.
