Whenever I needed SEO friendly urls in asp.net apps, I have been using UnidecodeSharpFork library to do just that. It is a good tool that transliterates Unicode to ASCII.

Unfortunately, published binaries on NuGet are not compatible with .net core and author of the tool was no longer working with .net.

Since the library is good and useful I decided to revitalize it: I republished it to GitHub: https://github.com/thecoderok/Unidecode.NET

In addition I created NuGet module and published it as well: https://www.nuget.org/packages/Unidecode.NET/

Feel free to use it and contribure.
