'EntityState' is an ambiguous reference between 'System.Data.EntityState' and 'System.Data.Entity.EntityState'

I'm getting the error

'EntityState' is an ambiguous reference between 'System.Data.EntityState' and 'System.Data.Entity.EntityState'

I'm getting this error on my 4 controllers using mvc5 entity framework.

The line in question is db.Entry(director).State = EntityState.Modified;

Same on each controller just different models.

no need to provide the fully-qualified. if there is two using on top of the page:

using System.Data; using System.Data.Entity;

just should delete (using System.Data;)

Note: delete another using like (using EntityState = System.Data.EntityState;)

You should use System.Data.Entity.EntityState instead of System.Data.EntityState.

There is two namespace added in your controller named System.Data and System.Data.Entity and both has EntityState property. Compiler is confusing here and gives you the ambiguous reference error. You need to specify the property with the namespace like

db.Entry(director).State = System.Data.Entity.EntityState.Modified;

Simply provide the fully-qualified EntityState depending on whichone you want: 

db.Entry(director).State = System.Data.EntityState.Modified;

or

db.Entry(director).State = System.Data.Entity.EntityState.Modified;
