The object cannot be deleted because it was not found in the ObjectStateManager

Question

I am getting this error \"The object cannot be deleted because it was not found in the ObjectStateManager.\"

My code is:

    protected MyEntities sql         


        

Answer 1

You should be sure that your object is exist in the list you are trying to remove from , you should put the following condition

if(context.entity.contains(your object))

remove it.

if you have a complicated condition for equality you should override equal method in entity class to put your condition for equality , to get the right way for an extension method "entity.contains"
