odd VS bug Application properties

[JohnH]

Found an odd bug in VS today, for a .Net 6 VB project the Application tab of project properties wouldn't open, I got "an error occured trying to load the page":

Same for Package tab.
Wondered if it was the VS 17.2.6, but another new .Net 6 VB project worked fine. Started dissecting the one that didn't and finally found that Nuget package WebView2 1.0.1264.42 was to blame, downgraded to 1.0.1245.22 and Application tabs shows again.
I have latest WebView2 runtime 103.0.1264.62 that was released just three days ago.
Checked with a .Net fw 4.8 VB project and that works with latest WebView2 nuget, also checked with C# projects .Net fw 4.8 and .Net 6 and they also work fine.
I think it will probably resolve in some way or another by updates later to VS or WebView2/runtime, but in the mean time if someone is troubleshooting the same they may find this post.

There's another bug that has lasted at least 17.2.5 + 17.2.6 though, for VB .Net fw 4.8 project you can't select startup form in Application tab... annoying for my test projects and some ad hoc tools where I frequently change startup forms. Would think I'm not the only one still using VB and .Net fw 4.8 and need set startup form.

I've seen a number of people complaining about that for a while. For the record, you can manually change the startup form if you click the Show All Files button in the Solution Explorer, open My Project -> Application.myapp -> Application.Designer.vb and then edit the code in the OnCreateMainForm method.

Good to know! The VB .Net 6 project is a bit cranky too for selecting startup form, but all you have to do is to unload and reload the project for Application tab to update - which can be done with the Project menu or context menu.

Consider using .net framework 4.8 instead of .net core; the winforms design experience is somewhat lacking in core+ (bit don't work, so MS just turned them off)

The startup form bug was fixed in 17.3.0.

You can also open Application.myapp and change <MainForm> node, the code change in Application.Designer.vb is then generated automatically.
