How to add downloaded library to C# solution?

Question

WPF

I downloaded a library that is not in nuget, added a link to it but a link to my computer, etc., how to add a library to a feng shui solution so that it gets into git and the link is to the path inside the solution

Answer 1

I usually make the Library folder on the same level as sln. In the project file, after adding the library, it should be

<Reference Include="CustomLibrary">
  <HintPath>..\Library\CustomLibrary.dll</HintPath>
</Reference>

This can be safely uploaded to git

Answer 2

Place the library in bin\Debug or bin\Release, where it should be, and add a link from there.
So Xamarin or WPF?
