Can this tool create .h & .lib files correspond to the C# function signature?

Question:
Can this tool create a .h file with the C++ function's signature?
Can it create a .lib file, so I can statically link to this DLL and won't need to do all this dynamic loading LoadLibraryEx\GetProcAdddress boilerplate error-prone code?

Can this tool create a .h file with the C++ function's signature?

You can get and format the list of exported functions as you need through -pe-exp-list (v1.6-RC)

#55 (comment)

DllExport -pe-exp-list bin\Debug\regXwild.dll

But without full signatures. It easy to implement for .net environment via Cecil etc., but for unmanaged C++ we need to implement translation to equivalents for marshaled types, and so on.

Can it create a .lib file, so I can statically link to this DLL and won't need to do all this dynamic loading

You can generate additional .exp & .lib when $(DllExportGenExpLib = true) (for Wizard see same option "Generate .exp + .lib ...") but of course only to reference exported definitions.

So how should I know what is the unmanaged c++ counterpart to an exported C# function?
My problem is that it seems I need to guess the signature.
Obviously, the DllExport knows what the right signature, as it creates an exported unmanaged function to serve as a proxy to the C# function, IIUC.
For example, if the C# signature is:

[DllExport]
public static void print(string str) {}

I guessed that if I call it as:

void print(const char* str) {}

it will work.
And fortunately, it worked :-)
But when I wish to find the unmanaged signature of:

[DllExport]
public static void printArr(string[] str) {}

I didn't find the right unmanaged signature :-(
Do I miss something on how to use this tool?

@BlueSolei Only primitive types and read more about PInvoke.

That is, use pointer to allocated string etc.

I updated solutions for how to use complex types and strings between unmanaged and managed environments:

But going back to the original question from this issue!

if this was not a misunderstanding and if it really is needed to someone, well, please clarify additional details. Probably I can implement something if this will be justified for some cases.
