Creating the LINQNorthwind solution

The first thing we need to do is to create a test solution. In this chapter we will modify a copy of our last solution, RealNorthwind, to test LINQ to Entities in the data access layer.

Note that you can create the solution from scratch if you like or you can just copy and reuse the RealNorthwind solution without any modification. If you are going to reuse the RealNorthwind solution, wherever you see LINQNorthwind in this chapter, you can just replace it with RealNorthwind and continue.

Here we will make a copy first then rename and change all the words Real to LINQ so that we will have a dedicated solution to test LINQ to Entities.

Now follow these steps to create this solution:

1. Open Windows Explorer and create a new folder, LINQNorthwind, under C:\SOAWithWCFandLINQ\Projects.

2. Copy all files and folders from the RealNorthwind project folder C:\SOAWithWCFandLINQ\Projects\RealNorthwind to the new folder C:\SOAWithWCFandLINQ\Projects\LINQNorthwind.

3. Under the...
