.Net Realms Assertion failed: !realm.is_in_transaction() turn on backtrace

Question

I'm using Realms on .Net and I get the error

The active test run was aborted. Reason: Test host process crashed : D:\a\realm-dotnet\realm-dotnet\wrappers\realm-core\src\realm\object-store\impl\realm_coordinator.cpp:1160: [realm-core-13.23.4] Assertion failed: !realm.is_in_transaction() 12:03:26:319 <backtrace not supported on this platform>

I get this error occasionally when running my test suite and I've tried to resolve this issue reviewing all my code with realms ensuring that everything that changes entries is within a realm.Write but this still occurs.

I mostly just want to get the backtrace to show. I'm using .Net 8 and realms version 11.6.1

I had a similiar issue where my unit test failed occasionally with xUnit. I fixed it by using this nuget package: https://www.nuget.org/packages/Nito.AsyncEx.Context I wrapped each test in an asynccontext like this:

 [Fact]
public void FilterTest()
{
    AsyncContext.Run(() =>
    {
        var realmservice = new RealmService();
        DateTimeOffset offset = DateTime.Today;
        var dateTime = DateTime.Today;
        var universalTime = dateTime.ToUniversalTime();
        DateTimeOffset dateTimeOffset = universalTime.Add(offset.Offset);
        var entry = new DiaryEntry() { Partition = "test", Date = DateTime.Today };
        var realm = realmservice.Get();
        realm.Write(() => realm.Add(entry));
        var result = realm.All<DiaryEntry>().FirstOrDefault(t => t.StoredDate == dateTimeOffset);
        result!.Date.Should().Be(dateTimeOffset);
        realmservice.DisposeRealm();
        return Task.CompletedTask;
    });
}

I think had has to do something how xUnit runs its test under the hood. Hopefully this helps.
