@Philip-Wang01 we don’t need it open, I’m going to close it. Thanks for the heads up.

After investigation, the test cases failed for similar reasons as 9322. This test case is a “console application”, not a “winforms application”. It can be fixed when <EnableUnsafeBinaryFormatterSerialization>true</EnableUnsafeBinaryFormatterSerialization> is added in the project file. But the status of this issue is still work in progress, @JeremyKuhne do we still need to keep the issue open?
