Ok, so I've checked out the kit from GitHub and made the changes and are trying to recompile the dll. Tried opening the solution in Visual Studio but it won't build, and also tried xbuild in the mono command prompt.
Building it in mono generates an error about UNC paths, which is solved if i changed ToolsVersion to 3.5 in System.Threading.csproj. (Don't know if this is proper way to solve that =)
Building again after that generates a lot of errors of the same kind:
CS0305: Using the generic type 'System.Action<T> requires 1 argument
CS0305: Using the generic type 'System.Func<T1, T2...> requires n arguments
Am I missing something in order to build the concurrency kit?
