Should().Be<T> breaks AssertionScope

[ip-crezco]

The following code fragment describes the problem:
try { using (var scope = new AssertionScope()) { foreach (var b in _Banks) { var redir = await client.CreateBankRedirectAsync(b, client.LocalRedirectAIS, GuidHelpers.GuidEncode(Guid.NewGuid())); redir.IsT0.Should().BeTrue(because: b.ProviderId); // below form is much nicer, but it seems to break the AssertionScope //redir.Should().Be<Uri>(because: b.ProviderId); } } } catch (Exception ex) { Logger.LogError(ex, "Test failed"); throw; }
