        <TargetFramework>net10.0-windows</TargetFramework>
        <ImplicitUsings>enable</ImplicitUsings>
        <Nullable>enable</Nullable>
    </PropertyGroup>
    <ItemGroup>
        <PackageReference Include="Interop.MFilesAPI" Version="26.2.2" />
    </ItemGroup>
</Project>

Expected behavior

Configuration

Which version of .NET is the code running on?
Microsoft.NETCore.App 10.0.2
.NET SDK 10.0.102

What OS and version, and what distro if applicable?
Windows 11

What is the architecture (x64, x86, ARM, ARM64)?
x64

Do you know whether it is specific to that configuration?
The problem also happens with Windows 10 x64, so is likely not specific to the configuration.

If you're using Blazor, which web browser(s) do you see this issue in?
N/A

Other information

Debugging shows that System.Reflection.MetadataImport.GetMarshalAs used to return an empty string in safeArrayUserDefinedSubType under .NET 8, but now (.NET 9 and .NET 10) decodes safeArrayUserDefinedSubTypeRaw into a garbled string in safeArrayUserDefinedTypeName in this instance. The method changed in a3dc133#diff-ca5f2236fd8d5cc746ac054393ca381a074ca52e5d7712a65b5a47cb804cfa46.
