New Page (Template Studio) WinUi 3 - tags helper

[MarekPio]

Describe the bug

When I create a new Template Studio Page (WinUi3) the tag helper does not work.

For Example I write "<TextBox" and it shows me "!{CDATA[]"

If I create a Page without Template Studio there is no problem. One of Template Studio Page fixed itself, but I do not remember how to do it. And now I want to fill a new page and have a problem with tag helper.

The "broken" Page has Properties

The working page does not have any properties in this windows. The pages I have created a few days ago and left them alone now are working correctly.

To Reproduce

1. Create new Template Studio Page
2. Open the Page
3. Write e.g. <TextBlock
4. See error: "!{CDATA[]" instead of xaml marks (tags?)

The computer restart fixed the problem. If i restart Visual Studio only there is a problem.

I need to do it each time for a new Page. It would be good to fix this.
