C# has https://github.com/dotnet/format but because C# is, well, not JS, the importance of linting is far less significant. Instead, there are hundreds of out-of-box analyzers that highlight problematic patterns or likely mistakes in the code and there are even more that you can enable through extensions (like Roslynator) or through packages that are 'dotnet add package' away.

On the package management - it couldn't be more different between Java and C# and it's incorrect to compare the two. .NET has few if any issues of the former.
