Looks like NCrunch doesn't know about ExtensionSDKs and doesn't copy those to its workspace.

Here is some info:
http://msdn.microsoft.co...8146.aspx#ExtensionSDKs

I ran into this because I used this for my project:

http://visualstudiogalle...-46c1-bc2d-2ffbde159c2b

Which installs an ExtensionSDK. In my project file, it looks like this:

<SDKReferenceDirectoryRoot>$(ProjectDir)\libs;$(SDKReferenceDirectoryRoot)</SDKReferenceDirectoryRoot>
</PropertyGroup>

...

<SDKReference Include="XUnit, Version=2.0">
<Name>XUnit for Managed Projects</Name>
</SDKReference>

I can workaround by using "Additional Files to Include", of course, but I think NCrunch should copy these automatically.
