Commandline nunit-console.exe NServiceBus.Config.UnitTests.dll /framework=net-4.0

Any ideas?

Answer 1

Combine Kev's advice ( add /framework=4.0.30319 to the parameter list) and modify nunit-console.exe.config with the following:

under

 <configuration>

add:

<startup>  <requiredRuntime version="v4.0.30319" /></startup>

under <configuration><runtime> add:

 <legacyUnhandledExceptionPolicy enabled="1" />

Answer 2

I was having the same issue with CC.net.

I now run NUnit from NAnt using the arguement /framework=4.0.30319

Hope this helps
