I have created a basic Radzen Blazor application with the .NET 5 framework. I added security to the application with the Default Provider and an MSSQL Express database. I finally added 2 users to the application.
If I try to delete a user right after its creation everything is fine. But if I try to delete a user that was first modified from the edit dialog, I get the following error message.
I have to refresh the browser to be able to delete a user that has been previously modified.
All the user management windows are those that were automatically created when the security was set up.
I also tried with the .NET 6 framework with the same result.
As I have already spent a lot of time looking for the cause of this error, your help will be greatly appreciated.
