The free Fix File Encoding extension prevents Visual Studio 2017/2015/2013/2012 from adding BOM to UTF-8 files.

Normally, when you edit a UTF-8 file in Visual Studio, it adds the byte order mark (BOM) sequence 0xEF, 0xBB, 0xBF to the beginning of the file. Sometimes it confuses other applications further processing the file. You can select an encoding manually (File - Advanced Save Options... or File - Save As... - Save with Encoding...), but you need to do it each time you reopen the file.

The free Text Sharp extension lets you adjust text clarity in Visual Studio 2017, Visual Studio 2015, Visual Studio 2013 and Visual Studio 2012 IDEs (Professional, Premium, Ultimate and LightSwitch). You can select Aliased, Grayscale or ClearType text rendering mode for Visual Studio menu, tabs and editor windows. An easy way to turn off ClearType. (Aliased rendering looks terrible when text scale is changed from default 100% in text views, so Text Sharp doesn't override VS settings when Aliased+Display is selected and zoom level is not 100%.)

It's a new feature of Visual Studio 2015 that works for C# and Visual Basic languages. The same outline is displayed when you change a method, class or namespace name.
