VS 2022 Webforms Slow Build

Doing some work with a Webforms project Using VS 2022. The builds (even with no edit changes) are taking around 25 seconds.

When comparing this using VS 2019, a build (with no changes) is almost instantaneous. A build with slight changes takes about 3 seconds.

I've looked high and low searching for a solution - most recommendations are to update to the latest version (which I have done). I have also tried resetting "settings" to the default.

Yes, I know - a difference of 20 seconds doesn't seem that much - but mounts up for 50 or 60 builds in a day.

Any help would be appreciated.

    Hi @Geoff Campbell ,
    Press Windows+R or open run from Start. Now type %temp% and delete everything from there... And then open Run again and type prefetch and delete everything from there also.
    Finally,open VS and see the performance.

    Best regards,

    Thanks for the suggestion, but that made no difference whatsoever. I deleted many "temp" files - while the prefetch command didn't seemingly do anything.

    The VS 2022 build procedure still took over 20 seconds.

    Hi @Tianyu Sun-MSFT

    OK, build output below - for some reason it wouldn't let me attach a text file. Both build and rebuild are almost exactly the same and take about 20 seconds to build.
