C# Code generation failure when using explicitly specified generic parameter that is user defined type. about qsharp-runtime HOT 2 CLOSED

Long story. Looks like:

we don't know the resolved type for DefaultT during compilation (which is odd, since the Type is explicitly set) --> which is causing the code to fallback to the runtime generic implementation --> at runtime the code can't identify the Type from the arguments (there are no arguments) and so it defaults to object --> QArray thinks object it's QVoid --> there is cast exception when a QVoid[] is returned instead of Complex[].

I would start at the beginning: figuring out why the C# code gen thinks DefaultT<Microsoft.Quantum.Math.Complex> still has open Type parameters, and take it from there. Somehwere around the SimulationCode.fs.

@vadym-kl This seems to be the same issue that was fixed with #88.
