Slow code snippet insert

Question

I use code snippets in Visual Studio for C# and have no problems. CTRL K + X brings up the menu and the snippet is instantly inserted.

However, when I try to insert an HTML snippet onto a webform page, there is a 5 second delay before it appears.

Here is my code. Any ideas on what is causing the delay? I've updated to latest version of VS2022.

Answer 1

This has nothing to do with your snippet and is replicable on any snippet in the webforms designer. You should use the Report a Problem tool in VS to report the issue to MS along with the repo steps. I can replicate it myself.

Note that you should confirm whether you're using the legacy web designer or the new web live preview designer (Tools \ Options -> Web Forms Designer). It could also be related to an extension.
