CSense (Code Sense) is an Emacs extension which provides features similar to IntelliSense or CodeSense in other editors:

• show help for symbol at point
• intelligent completion
• jump to definition

It consists of a frontend and language-specific backends. The frontend and the backends are completely separated. They can either be used together or separately.

The C# backend has been implemented first.

Here are a few screenshots of it in action:

• Symbol help with the multi tooltip showing overloaded functions. (screenshot)
• Function argument help showing the current parameter in bold. (screenshot)
• Intelligent completion. The class was found in the sources, instead of in an assembly, so the tooltip for the selected item shows the relevant code context as help. (screenshot)
