How to use

1. Install package
2. Inherit all necessary classes from EnhancedObject and mark them with EnhanceAttribute

[Enhance]
public class MyViewModel : EnhancedObject
{
    // class members...
}

3. Generate TypeDescriptionProvider and register it.

EnhancedTypeDescriptionProvider.CreateBuilder()
    .RegisterDefaultAssemblyLoadContext()         // register all generated by package containers in builder
    .Build()                                      // build TypeDescriptionProvider
    .Apply();                                     // register provider in application TypeDescriptor.
