Can't Enable Application Framework even with form as startup object

I have a Windows forms project, with application framework disabled. I want to enable it to allow for visual styles.

Application.EnableVisualStyles() doesn't cover things like trackbars. I've tested this with separate projects - enabling application framework seems to be what I want.

However, in my project, I can't enable the application framework - the option is greyed out. My Startup Object is definitely a form, but I still can't enable it.

Can you help me figure out what I have to do to enable the application framework for this project?

6 years later, I had the same problem. I had to open the app.manifest file and uncomment a dependency node at the bottom which was preceded by the following comment:

Enable themes for Windows common controls and dialogs (Windows XP and later)

If you need to create it the whole section is:

  <dependency>
    <dependentAssembly>
      <assemblyIdentity
          type="win32"
          name="Microsoft.Windows.Common-Controls"
          version="6.0.0.0"
          processorArchitecture="*"
          publicKeyToken="6595b64144ccf1df"
          language="*"
        />
    </dependentAssembly>
  </dependency>

If you are not starting from a MainForm, typically you would use a Sub Main in a Module:

Module Program

    Public Sub Main
        ' normal winforms startup
        Application.EnableVisualStyles()
        Application.Run(New MainForm)
    End Sub

End Module

You must enable visual styles before any UI elements are referenced which is why it wont work from the Form_Load event - it is too late.

Try looking for and deleting the binary file "Application.YourApp" under the "My Project" folder of your VB.NET project.
