Unable to run project after installing libraries via NuGet package manager. Metadata not found. How to decide?

Question

Programming

Started writing an application. I use Microsoft Visual Studio 2015. Through the NuGet package manager, I connected the MvvmLight library. And that's it, programming on this got up, since I can't compile the project. I deleted the libraries through the package manager, copied the libraries manually to the project folder, connected them manually, but the studio still writes errors. It's just brainwashing, why doesn't it work?

Severity Code Description Project File Line
Error Metadata file ' tests etc\DocumentationViewer\Libs\Microsoft.Practices.ServiceLocation.dll' could not be found Documentation.ViewModel F:\Programming\C#\Temporary, tests etc\ DocumentationViewer\Documentation.ViewModel\CSC

Here is the Visual Studio output

I do not understand, the libraries are not copied to the folder where all the compiled libraries and executables are placed?

Answer 1

the problem is most likely in which target framework is set in the project properties
when the library has a version of the required framework higher than the application in which it is connected, such an error occurs

Answer 2

1) Remove packages
2) Install them with nuget.
3) Click on solution -> Clean Solution
4) Try to build
