.Net applications.

I noticed that a few of my own applications were not being skinned properly so I thought I would delve into exactly why. Above is a Windows Form with various controls. Created in the latest patched version of Microsoft Visual Studio Community 2015. Using C# for a Classic Desktop app / Windows Form Application. (I never monkey around with WPF and other stuff.)
The rendering modes and appearance settings for many of them determine how they will be displayed. Most should be set to 'System' if the option is available and sticking to Normal tab pages. Buttons will not display correctly as the font settings do not appear to carry over. The background textures also do not appear to be rendering correctly for Menu bars and Tool Strips.
Other than these findings, everything appears to be displaying correctly.
