[Bug]: Issue Mocking EF Core EntityEntry

[Connor-Immix]

Description

First let me say I absolutely love this library, when I switched to it from xUnit I thought it was broken at first because it was so fast.

Unfortunately I have an error with the mocking library. Mocking the Microsoft.EntityFrameworkCore.ChangeTracking.EntityEntry type in EFCore 10 results in a build error.

Expected Behavior

To be able to mock the type without any errors. I want to use it to unit test a dbContext interceptor.

Actual Behavior

The generated source code has the following error preventing build:

'EntityEntryMockImpl.Instance': no suitable method found to override

Drilling down into the generated code the issue appears to be with this block:

 public override global::Microsoft.EntityFrameworkCore.ChangeTracking.Internal.InternalEntityEntry Instance
 {
 get => _engine.HandleCallWithReturn<global::Microsoft.EntityFrameworkCore.ChangeTracking.Internal.InternalEntityEntry>(39, "get_Instance", global::System.Array.Empty<object?>(), default!);
 }

Steps to Reproduce

using TUnit.Mocks;
using Microsoft.EntityFrameworkCore.ChangeTracking;

public class ReproduceError
{
    private void MockEntityEntry()
    {
        var mocked = EntityEntry.Mock();
    }
}

TUnit Version

TUnit.Mocks 1.37.36-beta

.NET Version

.NET 10.0

Operating System

Windows

IDE / Test Runner

Visual Studio

Error Output / Stack Trace

'EntityEntryMockImpl.Instance': no suitable method found to override

Additional Context

No response

IDE-Specific Issue?

• I've confirmed this issue occurs when running via dotnet test or dotnet run, not just in my IDE
