Is there an extension to syntax check embedded TSQL string

I've searched but found not very much. I'm seeking an extension for Visual Studio (ideally 2015) that I can use to syntax analyze embedded strings for valid TSQL syntax.

I looked at this:

https://github.com/DotNetAnalyzers/TSqlAnalyzer

But couldn't get it to work, documentation is close to nil.

Any suggestions much appreciated.
