VS2015 .NET 4.0 assemblies: No PDB could be loaded

[Sam13]

When compiling my .NET 4.0 solution with VS2015 RC1 (still under .NET 4.0) I'm not able to run OpenCover anymore. For all assemblies the following message is shown in the output:
Cannot instrument C:\Users\TestUserName\AppData\Local\Temp\nunit20\ShadowCop
yCache\9732_635712476997605454\Tests_5181666\assembly\dl3\a5254cd4\1cd770a8_f3b2
d001\SomeAssembly.dll as no PDB/MDB could be loaded

PDB does not exist on the shadow copy location only in the original location which is supplied as working copy path to OpenCover and NUnit.
When compiling under VS2010 the same procedure works...

Any ideas how to analyze this error?

What is your actual command line? Have you tried the -targetdir: option?

[Sam13]

Here is an anonymized version of my command line:

D:\Test\vendor\opencover\bin\OpenCover.Console.exe -register:user -target:"D:\Test\vendor\NUnit\bin\nunit-x86.exe" -targetdir:"D:\Test\bin\x86\Debug" -targetargs:"" -output:"C:\Users\Test\AppData\Local\Temp\output.xml" -filter:"+[*]* -[log4net*]* -[*nunit*]* -[msvcm*]* -[Rhino.Mocks*]* -[NLog*]* -[*UnitTest]*" -log:Error -returntargetcode -threshold:100)

The process OpenCover.Console.exe has also the same working directory than specified in -targetdir.

For some assemblies it works for some it doesn't. By changing nothing just using the VS2010 compiler it works for all assemblies...

Does the PDB exist in the targetdir folder? Was it built at the same time as the DLL? Have you tried the /noshadow option with nunit?

[Sam13]

1. PDBs exist in targetdir, verfied them by debugging, debugger was able to load them
2. Yes

but still no success

Sorry then I don't know, new one to me, I'll have to spend some time replicating it. Which version of OpenCover are you using? The latest one is in nuget.

[Sam13]

I was using the latest binaries from GitHub: 4.5.3522.
But with the new version from NuGet 4.5.3723 it works.

[molnargab]

Since the upgrade worked, the issue must have been the same as #248.

[sawilde]

@Sam13 - sorry my bad I forgot to upload the latest images to github - most people use nuget nowadays.

[Sam13]

I'm planning to do so ;-)

Is it intended that the newest version (4.5.3723) does not longer run on Windows XP? There is a registration failure reported.
Version 4.5.3522 works perfectly

[sawilde]

@Sam13 nothing I have done intentionally - I don't have an XP image and support from MS expired April 2014.

What is the error? And is anything in the Event logs?

[Sam13]

Yes I'm aware of that but that's out of my control...

Nothing in the event logs but a callstack (sorry for being lazy and not posting it toghether with the question):
An exception occured: Failed to register(user:True,register:True,is64:False):3 the profiler assembly; you may want to look into permissions or using the -register:user option instead.

With 4.5.3522 this works without any changes...

[molnargab]

Try running the command manually without /s, e.g. C:\WINDOWS\system32\regsvr32.exe /n /i:user.
It will open up a message box with the exact error message.
