Constructor taking LPCSTR (i.e const char*) no imported correctly

[IIFE]

Brief Description

Please refer to this repo for a reproducible example. If you build and run the app you'll get the issue faced.

I have a simple class with one constructor that takes a LPCSTR (typedef for const char*) param, and has a member of the same type.

The member generation is fine, however the constructor generation is incorrect. The constructor is imported as:
internal static extern global::System.IntPtr ctor(global::System.IntPtr __instance, global::System.IntPtr lpsz);

With the generated C# equivalent looking like:

        public Consumer(string lpsz)
        {
            __Instance = Marshal.AllocHGlobal(sizeof(global::CppSharpTestNative.dll.Consumer.__Internal));
            __ownsNativeInstance = true;
            NativeToManagedMap[__Instance] = this;
            __Internal.ctor((__Instance + __PointerAdjustment), lpsz);
        }

The last line is failing because the imported signature is expecting an IntPtr, but the generated class is using a System.String.

Is there a way to generate the import signature with the correct type, or modify the generated code to correctly convert to and from LPCSTR.

The LPCSTR member is generated fine with the correct marshaling:

        public string MLpsz
        {
            get
            {
                return Marshal.PtrToStringAnsi(((global::CppSharpTestNative.dll.Consumer.__Internal*) __Instance)->m_lpsz);
            }

            set
            {
                ((global::CppSharpTestNative.dll.Consumer.__Internal*)__Instance)->m_lpsz = (global::System.IntPtr) Marshal.StringToHGlobalAnsi(value);
            }
        }

The constructor however is not.

Thanks.

Thanks for the sample, it needs to be fixed.
