Description

When a call to a method uses a parameter whose type is embedded from an interop assembly, ILVerify fails to verify the dll with:

Error [MissingMethod]

Reproduction Steps

• Using Visual Studio 2022 create a .NET Framework (not .NET) Class Library named ClassLibraryInterop
• Add the NuGet package Microsoft.VisualStudio.Imaging (version 14.3.25407)
• Add the NuGet package Microsoft.VisualStudio.Imaging.Interop.14.0.DesignTime (version 14.3.26931). This interop assembly is automatically embedded, which is typical of the Visual Studio SDK used to create VSIX extensions for Visual Studio
• Add this code:

using Microsoft.VisualStudio.Imaging.Interop;
using System.Runtime.InteropServices;

namespace ClassLibraryInterop
{
   public class Class1
   {
      void f1()
      {
         ImageAttributes imageAttributes = new ImageAttributes
         {
            StructSize = Marshal.SizeOf(typeof(ImageAttributes))
         };

         Microsoft.VisualStudio.Imaging.ImagingUtilities.ValidateAttributes(imageAttributes);
      }
   }
}

• Build the DLL
• Open a command prompt and change to the output folder (ClassLibraryInterop\bin\Debug)
• Run:

ilverify ClassLibraryInterop.dll -r "C:\Windows\Microsoft.NET\Framework64\v4.0.30319\*.dll" -r ".\*.dll"

Expected behavior

No error (PEVerify from .NET Framework works fine in this case, but ILVerify doesn't)

Actual behavior

[IL]: Error [MissingMethod]
ClassLibraryInterop.Class1::f1()] Missing method 'Void Microsoft.VisualStudio.Imaging.ImagingUtilities.ValidateAttributes(Microsoft.VisualStudio.Imaging.Interop.ImageAttributes)'

This is likely because the signature of the method doesn't match due to the type of the parameter, which has been embedded:
