[ade-palmer]

Specific to Razor pages in Blazor project

[phil-allen-msft]

@ade-palmer , we're sorry you are running into this. In order to be sure we are investigating the right thing, can you add a screenshot of the 'expected' and the 'color brackets are not working' behaviors?

[ade-palmer]

Thanks for the response. Below are the images from a new Blazor Web App created in vscode. As you can see, the color brackets are fine in the program.cs file but are all white in the weather.razor file. The 'C#', '.NET Install Tool' and 'C# DevKit' extensions are installed.

[program.cs]

[weather.razor]

If I disable the C# extension (disables the C# DevKit extension also), The color brackets are now working as expected in the weather.razor file, but the PageTitle component is not happy due to these extensions being disabled
