My Visual Studio 2013 applications have blurry fonts when running on Windows 10

Question

After upgrading to Windows 10 my Visual Studio 2013 forms, when running, appear blurry and in a different style than what Visual Studio 2013 pictures it in design mode.

I tried installing Visual Studio 2015 and the blurry effects are still the same.

Also there are many other changes such as the elimination of 3D buttons.

Call external functions to set it across your entire application. It doesn't get any easier than this:

 [STAThread]
    static void Main()
    {
        **SetProcessDPIAware();** //THIS
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());
    }

    //ADD THESE TWO LINES !!
    [System.Runtime.InteropServices.DllImport("user32.dll")]
    private static extern bool SetProcessDPIAware();

Apparently this problem started with Windows 8, which I avoided like the plague.
This is the solution I found:

Add a manifest by going to to Project > Add New Item > Application Manifest File.

For Visual Studio 2015 and above, you can simply uncomment this code:

<application xmlns="urn:schemas-microsoft-com:asm.v3">
    <windowsSettings>
        <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true</dpiAware>
    </windowsSettings>
</application>

In older versions of Visual Studio, you need to add this code yourself as it won't be in the manifest automatically.
