CSharp tutorial will not build using the *.sln

1. tutorial/csharp folder does not contain a tutorial.thrift.
2. The tutorial.thrift in the root does not contain a csharp namespace.
3. The client and server source expect a namespace of CSharpTutorial.
4. The project references constant.cs, which the compiler does not generate.

Also, it's not at all clear where the generated source should go.

Also, the NuGet download for 0.9.2 does not contain a compiler (0.9.1 does).
