Opensource Visual Studio extension for compiler instrinsics in C/C++
Improved support for compiler intrinsics in Visual Studio. This extension can be found in the visual studio extensions gallery or download latest installer IntrinsicsDude.vsix (v1.2.2.0). If intrinsics are not low level enough, consider Asm-Dude.
QuickInfo is an IntelliSense feature that displays method signatures and descriptions when a user moves the pointer over a method name. The minimal default tooltips are replaced by more informative ones.
Statement completion is the process by which the language service helps users finish a language keyword or element that they have started typing in the editor. The minimal default tooltips are replaced by more informative ones. If the current keyword starts with _m the code completion key combination (typically CTRL+SPACE) will populate a separate completion list called Intrinsics. (Note: this feature is switched off by default.)
Signature Help (also known as Parameter Info) displays the signature of a method in a tooltip when a user types the parameter list start character (typically an opening parenthesis). As a parameter and parameter separator (typically a comma) are typed, the tooltip is updated to show the next parameter in bold.
If you are reading this you are most likely a C/C++ programmer, if you are still interested in some dirty C# you can run the extension from source code. To do that, Visual Studio 2015 SDK needs to be installed. To run the extension, hit F5 or choose the Debug > Start Debugging menu command. A new instance of Visual Studio will launch under the experimental hive.
