Barefoot learning LINQ (019): using the object relationship designer to create an object model

Http://u.115.com/file/f2b38fc3b2 demo

I have basically learned how to manually create the object model of LINQ to SQL. However, I do not think that I have mastered how to manually create this object model. There is still much to learn about. However, this is a question for a moment. At present, we have to stop it at this position first.

If you have used the object relation designer provided by Vs to create an object model, you will certainly agree with me: manually coding to create an object model is really a waste of effort! Correct! However, this statement is only limited to the first learning. In fact, it is not easy to start learning anything. From this perspective, it is no surprise. Even so, I strongly recommend that you master this manual encoding capability, because if you do not know about LINQ to SQL, You can manually encode it, you will definitely stare at. Maybe this is an exaggeration! However, it is better to try it out in project development! I can only say that it feels really nice.

I am so confused. How can I use the object relation designer to create an object model manually? Watch the video demonstration! That's more direct! However, here, I have to release an image to first see what the object model looks like in the object relationship designer? See:
