C# CSC.exe
If we give it a C# file, a .CS , is it able to compile it and say for example a ";" is missing at line 12 of your code? In a form that later in my program - which is Java RCP app, I can show those compile errors in a Spreadsheet
How about MSBuild? Is that able to show compile errors same as my previous example?
Think of MSBuild as a glorified make or something more like ANT - it is a language for describing compilation/build tasks. When you use MSBuild for building your c# program, you are actually using csc.exe for the compilation part.
Say this is your code (program.cs):
namespace MyCustomBuild
{
class Program
{
static void Main(string[] args)
{
System.Console.WriteLine("Hello World")
}
}
}
You can call csc program.cs and receive the following output
Microsoft (R) Visual C# 2010 Compiler version 4.0.30319.1
Copyright (C) Microsoft Corporation. All rights reserved.
program.cs(7,52): error CS1002: ; expected
Alternatively you can use msbuild to achieve the exact same result! Here is the content of build.msbuild
<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<Target Name="Default">
<Csc Sources="program.cs"/>
</Target>
</Project>
You can then call your msbuild file with varying levels of verbosity, as shown.
msbuild build.msbuild /verbosity:quiet and msbuild build.msbuild /verbosity:minimal

The remaining two verbosity levels are detailed and diagnostic and they present even more information if you want it. I'm not sure how much information you want for your spreadsheet, but hopefully one of these works for you.

Do all developers need to have the same local file structure?
For example if Sheldon uses C:\dev\foo are Raj and Howard not allowed to use d:\mycode\bar\foo?
How do i specify the TargetPath?
Or in other words What do i have to do to remove the cause for the warning?
I have an automation test suite, attempting to use SpecRun to run tests in parallel. It appears that rather than being able to run tests in Test Explorer, I need to instead run them using the provided "runtests.cmd" file...

I've set the system environment variable PATH to look for MSBuild.exe in C:\Windows\Microsoft.NET\Framework\v4.0.30319 (this is the latest version I have).
I tried to do as the error suggested, and found that both OurAutomation.csproj and OurAutomation.csproj.user files already have:
<Project ToolsVersion="15.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
So that's the simple fix out of the way - no fix at all, because the Project tag already has the required attribute and value!
I've been on several websites looking for an alternative solution. Others are saying that they had this problem when upgrading from VS2015 to 2017 (they changed from using project.json to *.csproj). However I have not upgraded. I created my project in VS2017. Target framework: .NET Framework 4.7.2, Output type: Class Library.
Not sure if SpecFlow.Tools.MsBuild.Generation is introducing a conflict here, but I do need it.
Please do you know how I would go about fixing this? Running out of ideas.
Thank you.
Pavel Anikhouski's answer was the solution, thank you!
"Starting from VisualStudio 2015 MSBuild is provided as part of IDE (or build tools), you should use this version, e.g. c:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\".

The underlying problem is fairly obvious to me after some searching (missing .NET Compact Framework) but I'm not sure how to solve it, as I installed mono-complete. But I don't know how to solve it. Help appreciated!
You may have a problem with case sensitivity. I had a similar problem with a program not finding Microsoft.CSHARP.Targets
It turns out that MSBuild provides a file called Microsoft.CSharp.targets
I created a symlink from Microsoft.CSHARP.Targets to Microsoft.CSharp.targets and that worked around the problem.
I am using dotnet to build a .NET Core C# project from the command line. The project has multiple classes with a main method. Thus I get the error:
$ dotnet build
Microsoft (R) Build Engine version 15.1.548.43366
Copyright (C) Microsoft Corporation. All rights reserved.
Test.cs(18,28): error CS0017: Program has more than one entry point defined. Compile with /main to specify the type that contains the entry point.
Build FAILED.
Passing the /main switch results in the error:
$ dotnet build /main:Test
Microsoft (R) Build Engine version 15.1.548.43366
Copyright (C) Microsoft Corporation. All rights reserved.
MSBUILD : error MSB1001: Unknown switch.
Switch: /main:Test
How can I pass the /main switch to the dotnet command?
You can edit your csproj to define which class to use (inside a PropertyGroup):
<StartupObject>foo.Program2</StartupObject>
or specify this MSBuild property on the command line via:
$ dotnet build foo.csproj -p:StartupObject=foo.Program2
where
namespace foo
{
class Program2{ public static void Main() {} }
}
Just to add why calling dotnet with /main fails with that error, note that it says "Compile with /main"; /main is a parameter for the compiler (csc.exe), not dotnet build. dotnet build will invoke MSBuild.exe which, in turn, will invoke csc.exe, but you'll need to tell dotnet build what the startup class is so it can tell csc.exe. This is what the accepted answer does.
Alternatively, if you were calling csc.exe directly, you could pass /main to it like so...
csc.exe Program.cs Test.cs /main:TestNamespace.Test
I have a simple HelloWorld application that I'm trying to build using NAnt. However, even with the simplest of build files, I still cannot get it to work. Below is my HelloWorld.build file.

Microsoft .NET Framework 3.5 (net-3.5) is not installed, or not correctly configured.
Object reference not set to an instance of an object.
However, the config file does have an entry for .NET 3.5 .This is with NAnt-0.86-beta and Visual C# 2008 Express Edition. Am I completely off track? If so, does anyone perhaps have a template build file that can be reused?
Thank you.
Well I tried your build file on a very simple console application and aside from tweaking the command line arguments it all works just fine for me.
Have you tried to reinstall the .net framework 3.5 as it definately looks like thats missing (what happens if you try and execute msbuild from the cmd line with the exact path from the 3.5 framework directory ?)
<?xml version="1.0"?>
<project name="HelloWorld" default="build">
<property name="nant.settings.currentframework" value="net-3.5"/>

Some times this error is because the build server does not have the sdk installed.
Try installing the windows sdk. You can download it on the Microsoft Download Center
Additional steps may be needed to get nant to recognize the sdk, please refer to this Page Brook's Blog Post
There is a bug in Nant 0.86, see
http://sourceforge.net/tracker/index.php?func=detail&aid=1986551&group_id=31650&atid=402868
for more info.
You can download Nant nightly build (currently nant-0.86-nightly-2009-05-05) which has this bug fixed.
