Just as Microsoft forked .NET Framework to make CoreCLR, they forked Mono. Both live in the http://github.com/dotnet/runtime http://github.com/dotnet/runtime repository. Both share most of the same C# code base for their runtime libraries. Mono is used for Blazor (WASM), iOS, and Android. This merging was announced as part of .NET 5 but I recall that it was not complete till .NET 6. https://devblogs.microsoft.com/dotnet/introducing-net-5/ https://devblogs.microsoft.com/dotnet/introducing-net-5/
