Can't find xUnit file in MS Visual Web Developer Express

Feb 16, 2012 at 11:43 AM
I have integrated NUnit as an external tool in MS Visual Web Devloper Express. This works fine, with the following parameters:

Arguments:    /run $(ProjectDir)/$(ProjectFileName)

Initial directory:          $(ProjectDir)
When I try to use exactly the same parameters for xUnit, I get two messages:
  -  Error loading assembly. Could not find file c:\run
  -  Could not find file:  c:\Documents and Settings\...........................\myProject.Tests\xunit.dll
I would be grateful for any advice.
