I am trying to use the NUnit.TestUtilities package in my NUnit test project. I have added the NUnit.TestUtilities.dll to the references in my test project. But I am getting the error "The type or namespace name 'NUnit' does not exist in the namespace 'NUnit.TestUtilities.Collections' (are you missing an assembly reference?)". I have added the NUnit.dll to the references as well. Any idea what I am missing?19I am getting the same error as the above user. I have added the NUnit.TestUtilities.dll to my references and I have also added the NUnit.dll to my references. I am still getting the error "The type or namespace name 'NUnit' does not exist in the namespace 'NUnit.TestUtilities.Collections' (are you missing an assembly reference?)". Any ideas?20I have the same problem as the above user. I have added the NUnit.TestUtilities.dll to my references and I have also added the NUnit.dll to my references.
