I’m using Wisej 4.0,9 with VS2026 latest version to build a Hybrid (.NET 9) project ( Hybridclient+ LocalClient).
Toolbox shows Wisej controls correctly the first time when i create a new Project but disappears after reopening the solution.
Designer shows “Loading designer…” then loads fully, no toolbox controls
Tried: toolbox reset, custom tab, rebuild, NuGet restore, project dependencies, reset ComponentModelCache:
Request guidance to make the toolbox stay permanently. NB it is only the wisej tool go missing other components are ok
i have included two images
Hello,
We have occasionally experienced this as well. It can be tricky to fix. What to try:
1.Keep retrying cleaning / rebuilding / deleting bin obj / restarting etc.
2. close designer, close VS, reopen
It may take 10+ attempts.
Hope this helps,
Julie
