[ryalanms]

This should be fixed with #3637. Thanks.

[jiangzeng01]

Thanks @ryalanms
According the conversation in #3637, the fix will come in .NET 5 servicing release, so is it will not be in .NET 5 RTM release?

[ryalanms]

This bug is fixed in .NET 5.0 RTM. The 'fix' that was reverted to fix this bug will be updated and reapplied in a servicing release (5.0.2xx).

[jiangzeng01]

@ryalanms Thanks for update, we will verify the bug with new RTM builds then.

[ryalanms]

Thanks.

[jiangzeng01]

Verified with 5.0.100-rtm.20515.8, the issue was fixed, so close.
