I tried some basic typing in a simple .cshtml file, but cannot reproduce the freeze. Maybe my testing environment is too simple. A simplified demo project may help.

I think I've managed to reproduce it on the test project. The freeze happens when you save the file first time. To reproduce it afterwards you need to delete hidden .vs folder in the solution directory.

I downloaded your project and tried it several times, yet can't replicate the issue. Utilizing the most recent Visual Studio 2022 Preview, I observed that delays in formatting .cshtml files no longer persist. It appears that Microsoft has at last rectified this complication. Please remove ".razor .cshtml" from Options > Format on save > Extensions cause delayed FormatDocument and see whether the freeze dissipates.

This has not effect, but if I put .cshtml in several denied sections like on the attached pic freezing stops (and obviously formatting).

Edit: putting it only in format deny is enough.

That's a bug: when you remove ".razor .cshtml" filter, the delayed filter is still active. It will be fixed in next release.

Additionally, I was wrong about the delayed formatting. Microsoft hasn't changed anything. It's just because my CPU is faster. I still need to find out what the problem is.

I've used WH_KEYBOARD to implement capturing input characters, and I'm not sure if this is causing compatibility issues. One possibility is that there might be a conflict with some third-party software.
