Problems encountered when first contacting ASP.NET MVC

Question

I used Visual Studio to learn ASP.NET MVC and created a simple modal named Albums and the corresponding controller. When debugging and running, I found that the default homepage could be accessed normally, but my own localhost:* /Albums does not work, the error message is as shown in the screenshot. How to solve this?

Answer 1

Post the route and take a look~

Answer 2

Visual inspection indicates that there is a problem with the database link. Let’s debug it.
