We are using ABP framework with EF and Blazor Web Assembly for implementation. I am not able to create Roles and Users to implement permissions on URL, Page ,Menu items and API. I verified in the logs and it is saying like "Savepoints are disabled because Multiple Active Result Sets (MARS) is enabled". We tried to modify connection string with MultipleActiveResultSets=false , even not able to create Roles and Users. Can you pls. help me in resolving the issue.
Ours is a tiered application with Blazor Web Assembly as a UI framework with Entity Framework and SQL Server.
• ABP Framework version: v5.3
• UI type: / Blazor Web Assembly
• DB provider: EF Core
• Tiered (MVC) : Yes
• Identity Server Separated : yes
• Exception in log file:
Savepoints are disabled because Multiple Active Result Sets (MARS) is enabled. If 'SaveChanges' fails, then the transaction cannot be automatically rolled back to a known clean state. Instead, the transaction should be rolled back by the application before retrying 'SaveChanges'. See https://go.microsoft.com/fwlink/?linkid=2149338 for more information. To identify the code which triggers this warning, call 'ConfigureWarnings(w => w.Throw(SqlServerEventId.SavepointsDisabledBecauseOfMARS))'
