Cannot implicitly convert type 'System.Data.EntityState' to 'System.Data.Entity.EntityState'. An explicit conversion exists (are you missing a cast?)
asp.net, c#, entity-framework
Solution
When you are using EF 6 or moving from EF 5 to EF 6, you should use `System.Data.Entity.EntityState` instead of `System.Data.EntityState`. This error happens when your project has reference to EF6 but you have code for EF5.
Also, check this link: When upgrading from EF5 to EF6 should I replace System.Data.Objects?.
Problem
I am getting this error in asp.net when using Entity Framework : "Cannot implicitly convert type `System.Data.EntityState` to `System.Data.Entity.EntityState`. An explicit conversion exists (are you missing a cast?)" Here is the snippet: ``` foreach (OrderLine line in order.OrderLines) { context.Entry(line.Product).State = System.Data.EntityState.Modified; } ``` Please suggest what should I do to resolve the error.
