Toolbox wisej 4.0.5 is missing where second open vsproject

Dear All

I had try to using new visual studio 2026 with wisej 4.0.5.

Create new project with .net core 8.

when project is first create, there wisej toolbox is show up.

But when i opening same project, the wisej toolbox is gone.

I had follow the forum instruction to find file wisej.core.dll and wisej.web.dll, i don’t find it in .nuget folder.

Any idea how to solve this problem, because i planning to using vs 2026.

(i was attach 3 file, project capture in choose .net core 8, picture the first time project was created has toolbox, and picture that toolbox is gone)

Thanks

Nicky
