In a project with the Async CTP for VS2010 - http://www.microsoft.com...ad/details.aspx?id=9983 - the NCrunch build fails as follows:

CSC (0)#0: Predefined type 'System.Runtime.CompilerServices.IAsyncStateMachine' is not defined or imported

The required library for the CTP (AsyncCtpLibrary) is copied to a relative "lib" path and referenced from there. I've tried adding the AsyncCtpLibrary.dll to the NCrunch "additional files to include", but it made no difference.

Any ideas?

Thanks,
Dave.

No, compatibility mode makes no difference. I've set all the options on all projects as described, and still get the same error.

If there are any logs I can produce, or anything else that could help just let me know. As the code (will be) open source, I'm happy to provide a link to it, if a sample project would help?

Thanks again for any further hints.

Dave.

I am also experiencing the same issues as Dave. I noticed he hasn't replied.
All you need to do to reproduce the problem is to install the Async CTP version 3 and include AsyncCtpLibrary.dll into your project.
http://www.microsoft.com...ad/details.aspx?id=9983

A simple test case:

using Nunit.Framework;
using System.Threading.Tasks;

[TestFixture]
public class MyFixture
{
[Test]
public async void MyTest()
{
await TaskEx.Run(DoNothing)
}

private void DoNothing()
{
}
}

This will not build in nCrunch, but it builds fine in Visual Studio 2010.

I am running win7 64bit and after installing the async CTP. I also installed. NET 4.5 (other programs I have rewire it).
I didn't check whether it was the installation of. NET 4.5 that caused this, but it could be. Still,, this configuration should work. I can compile the code manually and run the tests with NUnit.

I'll look into it on Tuesday when May long weekend is over.

Thank you for your patience and quick replies!

On a final note. I did get the library to work with .NET 4.5 installed.
Using this library instead of the AsyncCtpLibrary.dll:
https://www.nuget.org/pa...ges/Microsoft.Bcl.Async

Although it says it does not support Visual Studio 2010, it builds just fine as long as you have the async CTP installed in Visual Studio.

There is also another library that works (albeit not as perfectly), and it does not have the Microsoft license restrictions:
