VB.NET not seeing some classes

One of my classes seems to be invisible to the rest of my project. I wonder if I somehow have to initialize it before I can use its public s开发者_运维知识库tuff.

The functions and methods of Class1 immediately appear in IntelliSense, but Class2 is treated like a general (unknown) object.

I have some Public Shared functions in Class1 and Class2. I can call functions using

Class1.myPublicSharedFunction()

normally. However when I try this with any function from Class2, I get the error:

Error   1   Option Strict On disallows late binding.

even though their types are of course declared. If I copy and paste a working function from Class1 to Class2 and try to call it, it starts giving the same error. Any test function I declare in Class2 doesn't get its type recognized and is thus accused of trying to do late binding.

Both classes are public, and all the functions mentioned are Public Shared. I don't understand what makes the classes work differently. It's as if I needed to load or compile Class2 before VB knows its function types, but these things are supposedly automatic in VB.

What could be the cause of this?

When I begin typing Class2., IntelliSense lists is as a function, while Class1 is recognized as a class.

EDIT: If I copy the exact contents of Class2 into new class, only changing the line Public Class ... to the new name, everything works as normal. I thought it might be that the name was too long, so I copied the class to AnotherClassWithAReallyLongName, but this one worked too.

However, if I delete class2, and re-add it and paste back its contents, it still won't work.

As per comment you have something else in your code named `Class2’ that is hiding your new class definition. Remove it/rename it and your class will work.
