CS_IGNORE on constructors still generates dllimport

[jamesford42]

I have a class which is only allocated in C++ via a different a classes static method. So the constructor needs to be public but it contains parameters which do not exist in C#, hence I marked it with CS_IGNORE. However the dllimport lines in the C# wrapper class for that constructor (containing missing types) is still generated, even though it is never called.

Note: same result if i make the constructor private.
Note: same result if i add another constructor which is public/not-ignored and takes no parameters (the other constructor still appears as an import and breaks the build with its unknown types).

I tried to recreate this issue with:
https://gist.github.com/genuinelucifer/e2d636b1b021fc303f0b
.
What i guess is that there should be no generation of any internal member for a constructor marked with CS_IGNORE. That is entire:

            [SuppressUnmanagedCodeSecurity]
            [DllImport("Basic.Native.dll", CallingConvention = global::System.Runtime.InteropServices.CallingConvention.Cdecl,
                EntryPoint="??0ConstructIgnoreCheck@@QEAA@AEBV0@@Z")]
            internal static extern global::System.IntPtr cctor_1(global::System.IntPtr instance, global::System.IntPtr _0);

should not be generated.
.
Also, i see that the constructor definition is generated. But, I guess that should not be generated too. That is:

       public static implicit operator ConstructIgnoreCheck(int n)
        {
            return new ConstructIgnoreCheck(n);
        }

should not be generated.
Am i thinking correct?
