ASP.NET (C#) Question

Cannot implicitly convert type 'System.Data.EntityState' to 'System.Data.Entity.EntityState'. An explicit conversion exists (are you missing a cast?)

I am getting this error in asp.net when using Entity Framework :
"Cannot implicitly convert type

. 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.


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?.
