The visual effect doesn’t have to affect the code itself.

For example, ErrorTag will make the text Red and Bold. We can set Tags to apply some visual representation or effect on the code span it’s attached to. To change text formatting and color we will use Tags.Ī Tag instance usually doesn’t hold functionality by itself, but attached to a span of code. This will create a new instance of “DocumentedCodeHighlighterTaggerProvider” and other exported classes (We can also configure to always have the same instance returned). It’s somewhat similar to a Dependency Injection container like Unity. In our case, it allows us to add functionality to Visual Studio. Managed Extensibility Framework, MEF in short, is a framework by Microsoft to extend applications.

To be able to change code format, we’ll use two new technologies: Managed Extensibility Framework (MEF) and Taggers. In this part, we will show how to highlight all the text spans that have had documentation added to them. The documentation was then serialized to a file. If you followed the rest of the series, in the previous tutorial we allowed the user to select text and add documentation for the selection. This includes highlighting text by changing Background color, changing Foreground color and adding border. In this tutorial we’re going to learn how to highlight code in Visual Studio’s code editor. CodyDocs will save code documentation in a separate file and the extension will allow to view and edit the documentation in the editor itself. Each tutorial part is a standalone tutorial on a specific topic and can be viewed individually. Part 8: Add UI in the indicator margin with Glyphs During the tutorial we are going to build a VS extensions called CodyDocs and place it on GitHub.

Part 3: Add command to context menu and get selected code Part 4: Show a popup Window part 6: Follow a span of code with TrackingSpan Part 7: Insert buttons between text characters with Adornments Visual Studio 2017 Extension development tutorial part 5: Highlight code in Editor VSIX
