EntityFramework - Cannot Delete Entity using DbSet

Question

I am trying to delete an object from my database using EntityFramework's DbSet. The code is as follows:

var dbObject = FindById(id);
_masterDb.DbTable.Remove(dbObject);
_masterDb.SaveChanges();

I get the following error: "The object cannot be deleted because it was not found in the ObjectStateManager."

Please can someone tell me what I am doing wrong?

Answer 1

Possibly the entity is not attached to the same context.

Does this work:

var dbObject = FindById(id);
_masterDb.DbTable.Attach(dbObject);
_masterDb.DbTable.Remove(dbObject);
_masterDb.SaveChanges();
