@virajasawant06 Does this repro with net8.0? Not sure about it as we have not migrated code to .net8.0

Hey @virajasawant06, we're not able to reproduce your issue. Could you please send us a basic blazorserver setup that does repro it? We will use our own test credentials. Thank you!

Hi, Could you please let us know the exact components/files which are required to repro this issue ? As our code base is pretty much customized we wont be able to provide the existing code. We are using blazor server app with .net 6.0 and following are the package versions

This is the developer app we are using. Can you help us understand what needs to change, perhaps in Startup.cs or elsewhere, to reproduce your issue?

[jennyf19]

@virajasawant06 we cannot move forward without a repro from you, as we cannot repro it ourselves. Thanks.
