Hi, I have Visual Studio, the newest version, how do I edit or create files with the .sf extension (sampfuncs).

I will leave a sampfuncs mode below which I want to open in the visual project but when I open it I only show some digits (a hex code I guess), you can help me with more details about how I can make my plugin Sampfuncs? Tin to mention that I did not install absolutely all visual project but just the part of c ++, if there is something to add to go I do not know for sure, I expect the opinions of the connoisseurs.
