I have just had the same problem. In my case cause was one or more projects not having a Property element with a condition for one of the build configurations defined in the .sln file. NUnit tries to find a property matching each and every build configuration for each and every project that it wants to include, even if the sln file points at another configuration for the given build type.
It also seems that sometimes, if the default build configuration doesn't have any customised values it is not included in the proj file. -- You received this bug notification because you are a member of NUnit Developers, which is subscribed to NUnit V2. https://bugs.launchpad.net/bugs/1084471 Title: NullReferenceException in VisualStudioConverter.ConvertVSSolution Status in NUnit V2 Test Framework: New Bug description: When invoking the console runner.
