Cannot find the Dependencies Projects in VS2017

1 year ago
Hi,

I am using VS 2017, IIS 7.0, windows 10 and nop-commenerce version 4.1 to do my development. During development, one day, I started the project and rebuild solution and it had many similar error messages as followings and cannot find all dependencies, showed in Solution Explorer (Solution > Presentation > Nop.Web > Dependencies) but all dependencies files are physically in my computer. And it could be found/loaded sucessfully before. The Rubuild of the solution was no problem before.

I remove the dependencies, add them and rebuild it but the errors are the same.
Please kindly help me.

I restored my backup file to continuous my development. No idea about the crash of the Dependencies.
