Question

I had to have my primary HD replaced. Yesterday my HD was replaced by our IT tech staff. So today, after installing VS 2015, I started working on a WPF app we\'ve been working o

Answer 1

why we even need System.Web. Secondly, it isn't in the references of any project in the solution. I know, I've looked, but in VS 2015 AND opening the .csproj files directly. So, what is trying to use it? What needs it?

System.Web.Dll is old library responsible for whole http-protocol working. requests sending and creation. And you can find the system.web is member of system:

Besides, we can find the detail build log in the Visual studio Output, the system should be loaded, so if that assembly is missing or it is with a different version compared with the other referenced binaries, the assembly could not be loaded.

To resolve this issue, you could add it or create a new project with Visual Studio 2015 and copy the source files into this project. Then rebuild it, check if it works.

Hope those can help you.
