This is a screenshot of the VS2010 Object Browser. My first question is: Why are three namespaces used! Is this normal? If normally a number 1 is added after the second WebLogEntities, when you see such a naming, you usually know that there is a problem. What’s the explanation?
I encountered such a problem later when writing the Controller, as shown below
This prompt message appears in this picture. Not sure what to do? This is the second question.
According to the prompts given by the development environment, click the prompts in the picture to eliminate the red wavy lines, but I don’t know why, and there may be problems later!

This is the second day of learning ASP.NET MVC, so I forgot to give you some guidance!
