ASP.NET Add class and namespace missing

Question

Normally I can add classes to my ASP.NET project, but it is very weird and now I am getting this error when adding a class:

Also my project doesn't use any namespaces anymore. I created another clean ASP.NET project, but the same issue appears there too...

When I click "Yes" (Ja) then the class will be added to the project in a folder names App_Code, without namespaces, and when I click "No" (Nee) then the class will be added to the normal project folder, also without namespaces.

Anyone who can help me with this problem? I can't create new instances of my classes.

Answer 1

You are wanting to create a WAP: File → New → Web Application Project .

Websites use special folders. By putting code inside App_Code folder, it avoids JIT compilation issues. Namespaces are still there, but taken care of by the framework. Check properties, you will find the global namespace there.

Answer 2

You have created new project as "ASP.NET Web Site"

options:

1. re create a new Project.. "ASP.NET Web Application"

2. create a new Project.. "Class Library" in same solution then add reference form your website (right click on your web site project > "Add References.." > projects tab )

3. add any classes into App_Code directory
