Dotnet simple archetype does not include unit tests

Building a project created from the dotnet-simple archetype produces:

[INFO] [compile:testCompile]
[INFO] NMAVEN-066-013: Found Vendor = Vendor = MICROSOFT, Vendor Version = 2.0.5
0727, Framework Version = 2.0.50727, Executable Paths = [C:\WINDOWS\Microsoft.NE
T\Framework\v2.0.50727]
[INFO] NMAVEN-068-002: No source files to compile.
[INFO] Mojo Execution Time = 0
[INFO] [test:test]
[INFO] NMAVEN-1100-001: No Unit Tests

The dotnet-simple archetype should include an NUnit test case.
