Cannot access a disposed object. ObjectDisposed_ObjectName_Name

[knox007]

My blazor server program uses csla9.0.0, "Cannot access a disposed object. ObjectDisposed_ObjectName_Name" exception error occurs when I use dataportal on a page to fetch data from the database.When I used this dataportal to fetch data from a re-created console program, it was normal again, and no exceptions appeared, which made me feel strange. Does this happen to everyone?The same exception occurs if I use the csla.blazor.viewmodel method

Can you show your AddCsla code from Program.cs?
