How to make context menu apply dark theme when visual studio theme is changed to dark theme?

[Siyumii]

I have a WPF application which is implemented using MVVM pattern.It can be open,both left and right click actions. But the problem is when I right click it for the very first time, Context menu shows in white color. But When left click, Context menu shows in Dark color. I browse through the internet for a option to solve this but couldn't find anything. I appreciate any guidance or advice on this!
