error in asp.net

Hi Simon,

This error seems to be specifically about a project-level import trying to import 'app.config' as a namespace, which is incorrect.

You should try the following:

1. Check Project-Level Imports

In Visual Studio:

• Right-click your project → Properties
• Go to "References" tab
• Look in the "Imported namespaces" section
• You'll likely see a line with app.config or just app
• Uncheck it or remove it

2. Check .vbproj File Directly

Edit the project file:

• Right-click project → "Unload Project"
• Right-click → "Edit [YourProject].vbproj"
• Look for something like:

<ItemGroup>
  <Import Include="app.config" />
</ItemGroup>

or

<Import Include="app" />

• Delete these lines
• Save and reload the project

3. Auto-Generated Import Issue

Sometimes Visual Studio auto-generates this import incorrectly. Check:

• Solution Explorer → Show All Files
• Look for any hidden .vb files that might have this import
• Check if there's a namespace called 'app' somewhere in your code

4. IntelliSense/Auto-Complete Accident

This often happens when:

• You typed "app" and IntelliSense suggested "app.config"
• You accidentally accepted it as an import instead of a file reference
• It got added to project-level imports

You might also consider creating a blank project with the same configuration to help isolate the issue. This can help determine whether the problem lies within that specific project or if it's a broader issue with Visual Studio itself.

If the issue appears to be system-wide, I’d recommend doing a clean reinstall of Visual Studio to rule out any corrupted settings or components.

If these steps didn't help you, please give me your full error message and a brief look of your project structure.
