The default color scheme for Sublime Text Monokai is from Wimer Hazenberg, and I'm sure there are several attempts to port it to Visual Studio. I'm not sure if there is a full theme, since Sublime Text has very few user interfaces that can be ported.
Here are a few that I found on the Internet:
You can create Monokai (and others) color schemes for Visual Studio using base16-builder
There is a Monokai port for downloading Studio Styles.
... and several others available on GitHub
