Visual Studio 2026 with Qt Visual Studio Tools 3.5.0 extension very very slow
-
Hi,
I have a big solution with multiple Qt 6 projects and it takes a very very long time to open, close and build with the lastest version of Qt Visual Studio Tools 3.5.0 on Visual Studio 2026 (18.4.2). It takes more than 10 minutes to open or close the solution. The build process stucks multiple time for multiple minutes without output. Disabling the plugin seems to improve the situation.
Important thing to consider : If I open the same solution with Visual Studio 2022 (17.14.29) and Qt Visual Studio Tools 3.5.0, everything is working as it should. What's more, everything was working perfectly in Visual Studio 2026 just a few weeks ago. This is likely related to the latest versions of the plugin and/or Visual Studio.
Does anyone have a solution, because it’s unusable under these conditions?
Best regards,
Jonathan -
