Questions about ICorDebugEval2::NewParameterizedObjectNoConstructor

[viewizard]

Hello,

I am refactor netcoredbg debugger code and would like ask your help in clarification of ICorDebugEval2::NewParameterizedObjectNoConstructor work.

I found https://docs.microsoft.com/en-us/dotnet/framework/unmanaged-api/debugging/icordebugeval2-newparameterizedobjectnoconstructor-method with description provided Instantiates a new parameterized type object of the specified class without attempting to call a constructor method.. My test shows, that this method call static constructor, is not this mean that "NoConstructor" really call constructor? I am just confused by this method name, could you please confirm that static constructor are called?

I would like use it at static fields evaluation by ICorDebugType::GetStaticFieldValue and I found, that ICorDebugType::GetStaticFieldValue return S_OK even if static constructor was not previously called for type. Is the any way I could detect this? If no, is it safe call ICorDebugEval2::NewParameterizedObjectNoConstructor (that I believe call static constructor only once for type) unlimited times?

Just to be sure, I am right that ICorDebugEval2::NewParameterizedObjectNoConstructor don't execute normal constructor or finalizer by some reason in some case (I see we have ICorDebugEval2::NewParameterizedObject for this, but I better ask), and will not change debuggee process state in any way except user code execution in static constructor?
