I have a perfectly working C# page in a VS 2017 VB website built with .net 4.
But it won't load in the corresponding web application. Does this mean I can't mix C# and VB in a web application?

What I have tried:

I generated the requisite designer file. The page works fine in a C# web application project.

You cannot mix different languages in the same project.

There's nothing stopping you from converting the C# page into VB.NET.

Thank you, Dave. I have started the process.

You could mix languages in a web site project. :)

What a horrifying idea.

Maybe you are right. I got the VB page running in the web application, but it behaves strangely. Maybe there is a leak somewhere. I'll work on it for a while. If I can't fix it, you may hear from me again.

I started with a web site project 15 years old, but updated to .NET 4. It works fine. It uses MS Sql Server for a data store. My objective in moving to an application is to use a MySql store.
