Telerik UI for Blazor does not fully support Visual Studio 2022 Professional

Do you have a planned date for Telerik UI for Blazor to fully support Visual Studio 2022 Professional?

Telerik UI for Blazor cannot be used with Visual Studio 2022 Professional in Debug mode and Hot Reload. There are couple issues, see below, that seems to be related, and that Telerik are not willing to fix. Those issues render Telerik UI for Blazor unusable when working with Visual Studio 2022 Professional with Hot Reload.

Hello Stefan,

I confirm that our Dialog and Window are the only components with built-in modality.

I also investigated where the latest problem with the dataset error actually comes from. It looks like after hot reload, the component state is no longer the same, but it's not easy for the component to detect this.

This can probably be fixed, but requires refactoring and dev effort, which should be justified by higher customer demand. Currently, I see only two developers who have hit this problem, including you.

The issue manifests only during development and not in production with real users, and only in WebAssembly apps, not server apps. That's why the resulting severity and priority is lower, compared to other tasks.

The Window component has the same issue.

Please, don't try to downplay this.

Any page or component that utilizes Dialog or Window cannot be used with Hot Reload. Those 2 components are used to show errors to the user, so they are used on EVERY page. Do you have another component that can do that in modal way?

Hello Stefan,

I understand your frustration, but "lack of support for Visual Studio" is a very general statement. If you can list specific examples for incompatibilities, apart from the Dialog and hot reload, we are ready to investigate them. Otherwise, this item duplicates other existing items.

This is not a duplicate. The question is "Do you have a planned date for Telerik UI for Blazor to fully support Visual Studio 2022 Professional?"

It's also not an inconvenience. It has quite significant financial impact.

It doesn't matter what the reason is for the lack of support. Do you have the intention of fully supporting VS 2022? If yes, when?

Hello Stefan,

I apologize about the inconvenience that you experience while using hot reload with our Dialog. I believe we have already discussed why the problem is still pending a resolution.
