Microsoft has improved functionality, performance, and diagnostics in the MVVM toolkit portion of the .NET Community Toolkit. The upgrade was released this week.
Unveiled January 18, .NET Community Toolkit 8.1 adds dedicated analyzers to the MVVM (model-view-viewmodel) toolkit. Previously, the MVVM toolkit emitted diagnostics for features used incorrectly. Now, it can offer recommendations for improving code. Another analyzer has also been added to help reduce binary size in applications.
