 The IntelliJ Platform provides all the infrastructure that these IDEs need to provide rich language tooling support.

 However, Rider doesn't create a full [PSI](psi.md) (syntactic and semantic) model for C# files.
 Instead, it reuses [ReSharper](https://www.jetbrains.com/resharper/) to provide language functionality.
-All the C# PSI model, inspections, code rewritings, such as quick fixes, and refactorings are run out of the process, in a command-line version of ReSharper.
-This means that creating a plugin for Rider involves two parts - a plugin that lives in the IntelliJ "front end" to show user interface, and a plugin that lives in the ReSharper "back end" to analyze and work with the C# PSI.

 Fortunately, many plugins can simply work with the ReSharper backend.
 Rider takes care of displaying the results of inspections and code completion, and many plugins can be implemented without requiring an IntelliJ UI component.
