I write this piece of code with C# using ADO.NET Entity Framework.

I found error in here

```
var departmentQuery = from d in schoolContext.Departments.Include("courses")
                              orderby d.Name // here
                              select d;

```

Error message is like the following:

```
Cannot convert lambda expression to type 'string' because it is not a delegate type 

```

I am doing according this articles

Thanks in advance!
