Running NUnit 2.5 against Visual Studio 2010 .Net 4 code

 

I discovered that if you add the following to the relevant NUnit config file you can run a test dll built for .NET 4.0 in Visual Studio 2010 beta

Under <configuration> add:

<startup>
  <requiredRuntime version="v4.0.20506" />
</startup>

and under <runtime> add:

<loadFromRemoteSources enabled="true" />
