[UWP] Visual Studio development experience: high CPU usage and Intellisense unresponsive

[toburger]

When I add a UWP reference to a .NET 6.0 project Visual Studio gets very slow and uses all my CPUs.

Repro steps

I've started a hobby project to control my standing desk via Bluetooth. The source can be found here: https://github.com/toburger/IdasenDesk In order to work with Bluetooth I need to access the Windows.Devices.Bluetooth namespace, which is part of the Universal Windows Platform (UWP).

When I open the project in Visual Studio and start to edit the code Visual Studio eats all of my CPU and Intellisense gets unresponsive.

Expected behavior

"Normal" Visual Studio development experience.

Actual behavior

Intellisense gets unresponsive after editing code unless I rest for a while and let Visual Studio catch up.

Known workarounds

Just be patient. 😉

Will check it tomorrow on latest 2022 + do some profiling.

@vzarytovskii Did you do a check on this?

[vzarytovskii]

I think I did, and couldn't reproduce it on the main. Will re-check on latest 17.4.

Checked on today's build, it seems that all works fine. @toburger have you tested it on the 17.4 preview by any chance?

@toburger I can't reproduce it on the 2022, is it still a problem?
