I see that
ContextMenuStripGroupCollection, which is internal, overridesDictionaryBase, which is basically just a wrapper around aHashTablewith extra events we’re not using. As part of this issue, do you agree it would be a good idea for this class to use aDictionary<string, ContextMenuStripGroup>directly instead?ImmutablePropertyDescriptorGridEntry.PropertyValueis something I am not 100% sure on. It creates anHashTableinto anIDictionaryvariable, then passes that toTypeConverter.CreateInstance. I imagine the underlying converter probably relies on it being a hashtable? Anyone have any ideas on where the TypeConverter code is located?https://github.com/dotnet/winforms/blob/4f4829de9a3b4c56496a60ec18d774ca40956b53/src/System.Windows.Forms/src/System/Windows/Forms/PropertyGridInternal/ImmutablePropertyDescriptorGridEntry.cs#L47-L65
