I suggest joining Blazor. Blazor includes C# and .Net, but the handling of html5 and css is extremely time-consuming in comparison with xaml. C/XAML for HTML5 can cover that deficiency and create a formidable set.

Hi,

I suggest to have this feature added like in WPF.
HorizontalContentAlignment and VerticalContentAlignment in TextBox (and other text entry controls)

to share the size of rows and columns across multiple Grids controls (ColumnDefinition and RowDefinition) (WPF-only)

Need Devexpress 3rd party controls support asap

Support HierarchicalDataTemplate to go with the TreeView element

Reflection.Emit and dynamic type

without having to use a DataGridTemplateColumn every time. DataGridTextColumn is virtually useless because it cannot be styled

MultiBinding is a must-have feature. It is used extensively by virtually ALL moderate-to-large size WPF application. I wonder that not only it has not been added yet, there's no mention of the feature even in the upcoming roadmap.

Please add support for MultiBinding if you want serious WPF developers to consider this tool.

Supporting manifest generation, service worker development, and access to the extended api set to allow development of PWA apps

I'd like to use:
- Microsoft.Azure.Mobile.Server
- Microsoft.Azure.Mobile.Client
These are libraries that help connect and implement Azure App Services, which are crucial to making Azure Mobile Applications.

Please provide CRUD (insert,change,delete) support for Microsoft Azure SQL

The silverlight SDK contained many of the features missing from silverlight: A menu control, a validation summary control,etc. Our silverlight projects made heavy use of them.

A way to preserve changes made to generated javascript files. You might want to look at some of the older code generation systems to see how this can be done, but typically with markup code to define sections of the file that should not be overwritten. If users want to move the code to pure javascript, this enables the intermediate step of having some code ported while other code is not.

I tried it today an there was almost nothing I could do! even BeginAnimation is not supported!!! I tried to make a Border Brush with Gradient but nothing happend! do something about it please. I think you should mostly focus on xaml!

Many of the request here relates to this, but in general I feel there's currently insufficient .NET Types and Framework Classes support. Ideally should be 90%+ coverage
