Question

I have created an entity and it has a key of type Int. when I run the project and use this entity I get following error:

The ‘Id’ property on ‘Product’ could
not be set to a ‘Int64’ value. You
must set this property to a non-null
value of type ‘Int32’.

How can I fix it ?

Edit:

I am using SQL server and entity framework 4.1. I get error in controller action:

public ActionResult Test(long id) 
{ 
    return View(repository.GetObligor(id)); 
}

You mentioned that you defined entity with int Id but you are passing long Id. Try to convert it first to int or change Id in entity to long.
