I have a c# project that generates an EXE file. Now, I'm in a "secure" corporate environment, where I can compile my project, but I cannot execute the EXE file.
As a Java programmer, I'm wondering if there is not a way to compile the c# project into something that would not be an EXE file, but a CIL file and then execute the CIL file by something that corresponds to java.exe in the dotnet world.
EDIT in response to comments:
I can run exe files that have been installed by a package manager
Yes, I know the corporate policy is stupid.
Well, this should be pretty easy.
.NET executables are simply DLLs like any other - the main difference being the executable format itself, and the fact that EXE files have an entry point, while DLLs don't.
It also means that you can load the EXE into memory exactly the same way as you would with a DLL:
Assembly.LoadFrom("SomeExe.exe");
You're already half way there - now we just need to find and execute the entry point. And unsurprisingly, this is also pretty trivial:
var assembly = Assembly.LoadFrom("SomeExe.exe");
assembly.EntryPoint.Invoke(null, null);
For most applications, this should work perfectly fine; for some, you'll have to make sure the thread you're using to invoke the entry point has STAThread or MTAThread respectively (Thread.TrySetThreadApartment if you're starting a new thread).
It might need tweaking for some applications, but it shouldn't be too hard to fix.
So you can just make some bootstrap application ("interpreter") that only really contains these two lines of code. If you can't get even that approved, and you really need something as an "official package", try some .NET application that allows you to execute arbitrary code - for example, LINQPad, or PowerShell.
EDIT:
This does have limitations, of course, and it does introduce some extra setup work:
The bootstrapper has to target the same or higher version of .NET Framework. .NET Portable might be particularly tricky, but I assume you have that well under control. It also has to have the same bitness (if specified explicitly).
You need to run the debugging through the bootstrapper. That actually isn't all too hard - just go to project properties, debug and select "Start external program".
The bootstrapper has to run under full trust conditions - it's necessary for reflection to work. On most systems, this simply means you have to have the exe as a local file (e.g. not from a network share). Tools like LINQPad will run under full trust by default.
The application must not depend on Assembly.GetEntryAssembly. This isn't used all that often, so it shouldn't be a problem. Quite a few similar issues should also be fine since you build the application you're trying to run yourself.
I have a c# ClickOnce application that I need to be able to publish multiple times for OEM purposes.
The way I understand it now is that publish settings are located in the .csproj file.
However, this is inconvenient in the case where I want to publish multiple versions.
for example, Company A needs totally different icons, start menu location, product name etc. from Company B, but the assemblies need not be renamed.
Here are a couple approaches/questions that I can think of to solve this issue...
1.Is there a way to create a separate publish settings file to use during build time?
2.Can I edit specific publish settings (like Start Menu location, etc) at build time with MSBuild.exe? I think this would be ideal...
e.g.
MSBuild.exe project.sln /target:Publish /property:edit-project-publish-settings-here
3.Maybe create a 2nd .csproj file? (Would prefer not to do this...)
Please share your thoughts as to the best approach, or any other clever ways to make this happen. Thanks!
I wish I could give you some brilliant solution, but personally I would probably go with option 3.
I mean, its pretty simple, the changes should be pretty static and it will be difficult(ish) to totally screw it up and deploy the wrong changes to the wrong company.
If you copy the .csproj in your project folder, it will reference all of the same source files and you can just change the executable name. Create another VS solution and you can reference the copied .csproj and get rid of your first one so that you can publish two separate versions.
This isn't ideal for ClickOnce however.
If you use a Singleton object that specifies the "mode" (Company A, B, C, etc.) you can easily store that in the app.config (or another xml file). Then just re-publish your ClickOnce Application but copy the correct version of your configuration file in so it gets shipped with the build. This way, you don't need any additional csprojects Just include all of your icons and set them at run-time on App Start based on your Singleton object.
I found that you are able to edit certain properties using MSBuild.exe like this
MSBuild Solution.sln /target:publish /property:ProductName=ProductA\;Publisher=CompanyA\;ApplicationIcon=companyA.ico
I found another useful post on modifying.csproj files programatically with .NET code. (This would only be needed if you're modifying things that are deeper than just the project properties specified in the ClickOnce documentation below)
The MSBuild documentation here was also useful -- especially under Publishing Properties
We have a C# desktop application which we run for clients on various servers on a software as a service model. We are still on dot net framework 2.
The software has a architecture in which we have an independent application to catch external data thrown by some server. Then an application to make calculations based on it. Also one more application on which the client sees the output. The link between the 3 applications is another application which communicates with the DB.
The 4 solutions are on a SVN for sourcecontrol. But the release management is still manual and the patches are made manually by checking the log and including the dlls, pdbs, xml. etc for the projects for which the code has changed.
There is no assembly versioning implemented and the patch or release management is just done in the dark.
I want to know what is the industry practice for generating automatic patches from the code. Also I want a patch for each revision in the SVN. Also is assembly versioning helpful in this?
I have read much about continuous integration but it fails because we do not have unit tests and other fancy code to moniter the correctness of code.
The only thing at this time I would be interested is to implement a way to make patches which can be applied and removed easily. Also I want to know a way to determine the way we can monitor which release is at which level(or what patches have been applied) by some automated way rather than maintaining a log manually.
We use a build script which creates a SvnVersion.cs file containing the last commited revision. This file is placed in the root of the solution, and then added to all projects in the solution (but added as a link, not copied).
The template for the file (SvnVersion.Template.cs) looks like this:
using System.Reflection;
[assembly: AssemblyVersion("1.0.0.$WCREV$")]
[assembly: AssemblyFileVersion("1.0.0.$WCREV$")]
And we simply use TortoiseSVN to fill these placeholders in a batch script:
type "%TRUNKPATH%SvnVersion.Template.cs" > "%TRUNKPATH%\SvnVersion.tmp"
SubWcRev "%TRUNKPATH%\" "%TRUNKPATH%SvnVersion.tmp" "%TRUNKPATH%SvnVersion.cs" -f
IF ERRORLEVEL 1 GOTO ERROR
DEL "%TRUNKPATH%SvnVersion.tmp"
If you don't use TortoiseSVN, there are other ways to get this info in the file.
You will also need to remove this same information from your AssemblyInfo.cs files or you'll get a compile error. Also, to speed up Debug builds, this is only executed in Release builds (and in Debug builds only if the file doesn't initially exists, like after a fresh checkout).
We have a moderately sized solution, with about 20 projects. In one of them I have my business entities. On compiling any project, visual studio waits and hangs about one and a half minutes on this BusinessEntities project.
I tried our solution in SharpDevelop and it compiles our complete solution, in 18 seconds. Similar timing with MSBuild.
My guess is that VS is trying to find out if the project needs a compile, but this process is about 15 times slower than actually performing the compile!!
I can't switch to the great sharpdevelop, it lacks some small, but essential requirements for our debugging scenarios.
Can I prevent VS from checking this project, And have it compile the projects without such a check, just like sharpdevelop?
I already know about unchecking projects in configuration management to prevent building some projects, but my developers will forget they need to compile this project after updating to latest sources and they face problems that seem strange to them.
Edit: Interesting results of an investigation: The delay happens to one of the projects only. In configuration manager I unchecked all projects, then compiled each of them individually. All projects compile in a few seconds!! The point is this: if that special project is built directly, compiles in a few seconds, if it is being built (or skipped, because it is up-to-date) as a result of building another project that depends on it, VS hangs for about a minute and half, and then decides to compile it (or skip it). My conclusion: Visual studio is checking to know if any files are changed, but for some reasons, for this special project it is extremely inefficient!!
I'd go to Tools -> Options -> Projects and Solutions -> Build and Run and then change the "MSBuild project build [output|build log] verbosity" to Diagnostic. At that level it will include timings which should help you track down the issue.
We had the same problem with an ASP.NET MVC web project running in Visual Studio 2013. We build the project and nothing happens for about a minute or so and then the output window shows that we are compiling.
Here's what fixed it... open the .csproj file in a text editor and set MvcBuildViews to false:
<MvcBuildViews>false</MvcBuildViews>
I had to use sysinternals process monitor to figure this out but it's clearly the cause for my situation. The site compiles in less than 5 seconds now and previously took over a minute. During that minute the Asp.net compilation process was putting files and directories into the Temporary Asp.net Files folder.
Warning: If you set this, you'll no longer precompile your views so you will lose the ability to see syntax errors in your views at build time.
There is the possibility that you are suffering from VS inspecting other freshly built assemblies for the benefit of the currently compiling project.
When an assembly is built, VS will inspect the references of the target assembly, which if they are feshly built or new versions, may include actually loading them in a .Net domain, which bears all the burdens of loading an assembly as though you were going to run it. The build can get progressively slower as it rebuilds more and more projects. When one assembly becomes newer the others do a lot more work. This is one possible explanation for why building by itself, versus already built, versus building clean, all have seemingly relevantly differing results. Its really tht the others changed and not about the one being compiled.
VS will 'mark down' the last 'internal' build number of the referenced assembly and look to see if the referenced assembly actually changed as it rolls through its build process. If its not differnt, a ton of work gets skipped. And yes, there are internal assembly build numbers that you dont control. This is probalby not in any way due to the actual c# compiler or its work or anything post-compile, but pre-compile steps necessary for the most general cases.
There are several reference oriented settings you can play with, and depending on your dev, test, or deployments needs, the functional differences may be irrelevant, however may profoundly impact how VS behaves and how long it takes during build.
Go to the references of one of the projects in Solution Explorer:
1) click on a reference
2) open the properties pane if its not (not the Property Pages or the Property Manager)
3) look at 'Copy Local', 'Embed Interop Types', 'Reference Output Assembly'; those may be very applicable and probably something good to know about regardless. I strongly suggest looking up what they do on MSDN. 'Reference Output Assembly' may or may not show in the list.
4) unload the project, and edit the .proj file in VS as text. look for the assembly reference in the XML and look for 'Private'. This means whether the assembly referenced is to be treated as though its going to be a private assembly from the referencing assemblies perspective, vs a shared one. Which is sort of a wordy way of saying, will that assembly be deployed as a unit with the other assemblies together. This is very important toward unburdening things. Background: http://msdn.microsoft.com/en-us/magazine/cc164080.aspx
So the basic idea here is that you want to configure all of these to be the least expensive, both during build and after deployment. If you are building them together, then for example you probably really don't need 'Copy Local'. Id hate to say more about how you should configure them without knowing more about your needs, but its a very fine thing to go read a few good paragraphs about each. This gets very tricky however, because you also influence whether VS will use the the stale old one when resolving before the referenced one is rebuilt. As a further example explaiing that its good to go read about these, Copy Local can use the local copy, even though its stale, so having this set can be double bad. Just remember the goal at the moment is to lower the burden of VS loading newly built assemblies jsut to compile the others.
Lastly, for now, I can easily say that hanging for only 1.5 mins is getting off very lucky. There are people with much much worse build times due to things like this ;)
Some troubleshooting idea's that have not been mentioned:
Clean solution?
Delete Obj and Bin folders plus the .suo file? FYI, neither Clean nor Rebuild will delete non-build files, eg files copied during a pre-build command.
Turn off VS scanning outside files. Options > tools > environment > document > detect when file is changed outside the environment?
Rollback SVN history to confirm when it started to occur? What changed? If the project file on day 1 takes the same time, recreate the project, add all the files and build.
Otherwise could you please run Process Monitor and let us know what Visual Studio is doing in the prep-build stage?
Sounds silly, but remove all breakpoints first. It sped up my pre-build checks massively - still don't know why though.
Based on the (limited) information provided one possibility is that there could be a pre-build action specified in the project file that is slow to compile.
Try disabling platform verification task as described here.
If your individual projects are compiling correctly then all you can do is change order of compilation by setting dependent projects explicitly in configuration.
Try to visualize your project dependency hierarchy and set dependent projects. For example, if your business entities project is referenced in each project, then in configuration of each project, this project must be selected as dependent.
When an explicit build order is not set, visual studio is analyzing projects to create an order of building project. Setting explicit dependent projects wiki make visual studio skip this step and use the order provided by you.
With such an extreme delay on a single project and no other avenue seeming to provide a reason I would attempt to build that specific project while running procmon from sysinternals and filter out all the success messages. You could probably also narrow it down to just the file system actions as well. From your description I might guess that the files are being locked by an external source like the event collection or workflow management process services.
Other things to consider would be whether or not this is a totally clean build machine or if it has been used to perhaps test the builds as well? If so, is there a chance that someone mapped an IIS application path to the project directly or registered it as a service location?
If you run procmon and see no obvious locks or conflicts I would create a totally new solution and project and copy the files over to see if that project also has the same delay. If it does have the same delay I would create a sample project of the same type but generic data (essentially empty) and see if that too is slow. If the new project with the same files builds fine you can then diff the directories to see what the variance is that causes the problem (perhaps a config or project setting).
For me, thoroughly disabling code analyzers helped per instructions here:
https://learn.microsoft.com/en-us/visualstudio/code-quality/disable-code-analysis?view=vs-2019#net-framework-projects.
I thought my code analyzers were already off, but adding the extra xml helped.
Thanks Kaleb's for the suggestion to set "MSBuild project build [output|build log] verbosity" to Diagnostic. The first message took more than 10 seconds to display:
Property reassignment: $(Features)=";flow-analysis;flow-analysis" (previous value: ";flow-analysis") at C:\myProjectDirectory\packages\Microsoft.NetFramework.Analyzers.2.9.3\build\Microsoft.NetFramework.Analyzers.props (32,5)
Which led me to the code analyzers.
Just in case someone else trips into this issue:
In my case the delay was being caused by an invalid path entry in "additional include directories" that referred to a non accessible UNC location.
Once this was corrected, the delay disappeared.
In C++ projects there is the possibility to set a custom build step for files. Is there a similar functionality in C# projects? I couldn't really find anything.
One idea would be to create a second project (makefile or c++) and move the files there.
MsBuild should work for you although it might take some time to figure out how it works. It appears that you can setup a step that runs prior to building each .cs file by separating each .cs file into its own build group.
In MSBuild script for compiling each .cs file into an EXE, Dino Chiesa comments:
By using the %(CSFile.identity)
scalar, we run this task once for each
file. The converse would be
#(CSFile.identity). That would run
the compile once, for all files,
compiling them all together into a
single assembly.
Also, these links might help:
Custom build step for C# files
Master Complex Builds with MSBuild
No custom build step for individual files with C# projects. You could probably hack something together with MSBuild...
Look at the BeforeBuild and AfterBuild targets in your csproj file.
I think you are on the right track with your comment about multiple projects. Combine this with the fact that you can include multiple projects within a single Solution and you may have your answer. I use this functionality to build several components at a time and it works quite well.
