Hi there,

I have recently upgraded to the latest build of NCrunch having had the my previous version working quite happily for months and all of a sudden my test projects will not load and show the tests. I have been through several phases of fully uninstalling, reinstalling, manual installation, checking settings etc but to no avail. The error I get in full is bellow, not sure what else you would need from me, let me know if there is anything i can give you to make tracking this problem down easier.

Thanks
Henry

An error occurred while analysing this project after it was built: System.IO.FileNotFoundException: Could not load file or assembly 'nunit.core.interfaces, Version=2.6.3.13283, Culture=neutral, PublicKeyToken=96d09a1eb7f44a77' or one of its dependencies. The system cannot find the file specified.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Hi Remco,

I have just retried the installation as you described, fully uninstalling using programs and features, removing the 'Remco Software' folder entirely from the extensions directory before reinstalling with the MSI and I'm afraid I still get the same error reported.

With regard to the NUnit ncrunchmodule file, I have both the 'nCrunch.Module.NUnit.crunchmodule' and 'nCrunch.Module.NUnit.dll' in the root folder 'C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Remco Software\NCrunch for Visual Studio 2015' i assume these are the files you are referring to?

Sorry for the bad news, anything else I can try or send you to make things clearer?

Hi Remco,

Sorry for taking so long to get back to me, it turns out this might actually be something that is not an installation issue. I found that some projects would work perfectly on my visual studio instance with NCrucnh doing all the cool things I have come to expect it to do. Every time I went back into my main work project however I would start getting these issues. I figured I would go back to basics and start a solution from scratch which would exhibit this strange behavior and I seem to have been able to do just that.

It turns out that we use FSCheck in our project and as part of it's nugget install it creates an addin file containing the following:
/// <summary>
/// Required to make NUnit play nicely with FsCheck
/// </summary>
[NUnitAddin(Description = "FsCheck addin")]
public class FsCheckNunitAddin : IAddin
{
public bool Install(IExtensionHost host)
{
var tcBuilder = new FsCheckTestCaseBuilder();
host.GetExtensionPoint("TestCaseBuilders").Install(tcBuilder);
return true;
}
}

This is the file that seems to break the analysis. If I comment out the contents of the file it seem to run all our FSCheck tests correctly and as such I think I can probably get around this for now. Just wanted to post back in case anyone else was having the same pains and also to inform you that something seems to be a little screwy with the way these tests are now working. Looking at the history of the FSCheck files in our source control this must be caused a change that was introduced within NCrunch itself since the test has been running well on previous versions of NCrunch for a while (I'm afraid I'm not sure which build broke it).

If you would like a really simple sample app that displays the issue let me know I have one now :)

Thanks for your help
Henry
