Are there any repositories with modules for C#?

Question

C++ / C#

Good afternoon.
I am new to .NET (C#).
Tell me, please, is there one large repository for C # with Open Source solutions?
JavaScript has NPM (Node Package Manager) for the server side, and Bower for the client side. You can go to their website, enter the name of the package, and find the right ready-made solution, immediately start using it in your project.
Are there similar repositories for C# (github not considered)?
