I got following error while using application with concurrent users...
System.ArgumentException: An item with the same key has already been added.
Server stack trace:
at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
..........................
How to fix this exception..? I have checked property name and data types. there is no same name properties/variables.. And also cross checked base entity and derived entities..
If any one faced this kind of exception earlier, give me the workaround to fix the issue
