Custom objectset extension methods

Question

I have tried Googling strings like "c# ef objectset extension methods" but I suppose I'm using the wrong terms here, because I can't find anything relevant.

What I would like to know is how I add a custom extenstionmethod that I can use on my database context:

context.TABLE.MyMethod(...

I assume that there are a lot of SO threads covering this, but I can't find them.

Answer 1

public static class YourExtensions
{
    public static void MyMethod<T>(this DbSet<T> table)
       where T: class // this constraint is required because DbSet<T> have it
    {
        // code here
    }
}

Here is MSDN article on Extension Methods
