Web项目已在Visual Studio 2017中成功构建，没有任何错误，但仍显示为错误

Question

I am Using Visual Studio 2017 as IDE for developing asp.net mvc based web application. In asp.net Project i have referrenced the class library application for three tier architecture. When I build the solution, it builds successfully and could ran also. But when I see my project code it shows like "are you missing directive or an assembly reference error" in many places. Because of that code intelligence is not working. Even I have to do build for single code change to check whether any of the compilation error exists in my code.

I have did the following, but not helped any how,

1. Clean solution --> And rebuild the solution
2. Restart the Visual studio and rebuild the solution
3. Removing the .suo file in solution directory

Thanks in Advance..!

Answer 1

I resolved this issue by reinstalling the EntityFramework library to all the project in the solution. After that it works fine.
