Intensive outpatient programs providing structured care and therapy. IOP Programs Los Angeles

I think my programming skills are outdated because I still use frameworks like ASP.NET, but in general they are enough for me. However, my management said it's time for me to develop as a specialist, so I decided to polish the theory, familiarized myself with the SDK from visioforge https://www.visioforge.com/ , and they have been using Xamarin, MAUI and Avalonia for a while now. Who has experience with this software? Which SDK frameworks do you use to write cross-platform .Net programs?
