Hello!

There is a problem I need help with your query on the data using LINQ to SQL and Entity Framework (I'm using Visual Studio 2010).

My picure here: http://img.tamtay.vn/files/photo2/2010/5/28/10/962/4bff3a3b_1093f58f_untitled-1.gif

I have three tables:

tbl NewsDetails
tblNewsCategories
tblNewsInCategories

(See screen 1 in my picture)

Now, I want to retrieve records in the tblNewsDetails table, with condition: CategoryId=1, as the following results:

(See screen 2 in my picture)

But NewsID and CategoryId in tblNewsInCategories table is two foreign key, I do not see them and I do not know how to use them in your code.

My code has errors:

(See screen 3 in my picture)

Please help me. Thanks!
