An exception of type 'System.InvalidOperationException' occurred in EntityFramework.dll but was not handled in user code
Solution :
This is a very common message appears when you modify existing Table or add a new table. This appears because EF stores entity information in database itself and that is not updated since you modified table structure through your Code. Now, all you need is perform Code First Migration . Do this migration every time you modify or add new entity.
If using Code First then enable code first migrations
1. Add entity class
2. enable migration from package manager consol
3. update databse from package manager consol
If using model first approach then Update edmx file.
Users Please post your solution too.
