How do I ignore Build_info for git?

I'm using the standard Unity .gitignore file, but I have two problems: everytime I run the game Unity generates/updates a build_info file and a .csproj file.

I see csproj even is already in the ignore, but yet Visual Studio wants me to push this every time. What am I doing wrong?

 /Assets/StreamingAssets/build_info.meta

For the last two lines which contain the build_info file, I tried both with and without .txt. The info I found on Google was to include .txt (which doesn't work) so I also tried without because Windows Explorer doesn't show the extension. (also without luck)

I was suggested to right click -> ignore the file in Visual Studio in the Team Explorer tab before pushing. But this ignore option is not available for this file. (it is if I try it on a .png)

Any suggestions?
