Hi All,

by looking at our logs we noticed repeating issues with collections being modified in couple of methods inside Casbin.NET library. See please the screenshots from the logs:

Can somebody please take a look at it?

Thank you,

Martin

The model at Casbin.NET v1 is not thread-safe default, please make sure synchronous call model instance.

You can try to use SyncedEnforcer.Create() to create an enforcer instance at Casbin.NET v2.

Thank you for the info. As I can see v2 is still in the preview. When do you plan to release standard version?
