CoreRT compile failed

[ryancheung]

I just made a library with SharpGenTools and tried to test corert compiling. It raised the error:

ImeSharp.Demo.obj : error LNK2001: unresolved external symbol WindowsCreateString [D:\TeamIG\ImeSharp\ImeSharp.Demo\ImeSharp.Demo.csproj]
bin\Release\netcoreapp3.1\win-x64\native\ImeSharp.Demo.exe : fatal error LNK1120: 1 unresolved externals [D:\TeamIG\ImeSharp\ImeSharp.Demo\ImeSharp.Demo.csproj]

The SharpGen.Runtime.COM package has this file:

using System;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;

namespace SharpGen.Runtime.Win32
{
	// Token: 0x0200003D RID: 61
	internal static class WinRTStrings
	{
		// Token: 0x060000D8 RID: 216 RVA: 0x00003F98 File Offset: 0x00002198
		public unsafe static void WindowsCreateString(string sourceString, uint length, out IntPtr text)
		{
			Result result;
			fixed (IntPtr* ptr = &text)
			{
				void* param = (void*)ptr;
				fixed (string text2 = sourceString)
				{
					char* ptr2 = text2;
					if (ptr2 != null)
					{
						ptr2 += RuntimeHelpers.OffsetToStringData / 2;
					}
					result = WinRTStrings.WindowsCreateString_((void*)ptr2, length, param);
				}
			}
			result.CheckError();
		}

		// Token: 0x060000D9 RID: 217
		[DllImport("api-ms-win-core-winrt-string-l1", CallingConvention = 3, EntryPoint = "WindowsCreateString")]
		private unsafe static extern int WindowsCreateString_(void* param0, uint param1, void* param2);
	}
}

It seems the DllImport of WindowsCreateString is wrong?

Has anyone tried compiling with CoreRT?

After upgraded to SharpGenTools v2, this is fixed in Native AOT.
