REQUIRED Visual Studio version?

Which is the oldest supported version of Visual Studio usable to (try to) compile a C/C++ gauge for a target x64 system, using P3DV4 gauges.h?

I've read 2015 is the suggested one, and it seems to be absolutely required to compile programs using SimConnect interface, but what about a simple gauge? Would VS2010 work?

Also I tried, without success, to find the free version of VS2015. Is it still available online from Microsoft?

Thank you very much in advance!
The more I try to understand the less I do actually understand (hope this is correct in english):( .
Looks like the "express" version is gone and now the Community Edition has to be used (license terms, see below, are mostly unknown to me).

@WebSimConnect: Thank you very much! The link you provided points to a VS2015 Community edition ISO.
I downloaded it and installed it, it did not require a key, you have to accept usage conditions which seem to dictate that for single user it is free (but I'm absolutely not sure of this, URL is An example:

Individual license. If you are an individual working on your own applications to sell or for any other purpose, you may use the software to develop and test those applications.

"For free" has to be considered implicit? So that it becomes: "you may use the software to develop and test those applications for free"?
Who knows. I'm not an a lawyer...

@SkippyBing: Thank you too, but the link you specified brings you to a Community Edition of VS2017.

Once again thank you,

Yes, for free.

If you scroll to the bottom of the page that SkippyBing links to (as he tells you to), VB2015 links are present.
