This plugin adds Unity specific functionality to ReSharper and Rider.

Rider is JetBrains' cross platform .NET IDE, which uses ReSharper out of process to provide language support - which is why it can run ReSharper plugins. See below for installation details.

Please see the Unity3dRider plugin to add support to the Unity editor to open C# projects, files and error messages in Rider.

• Event functions and fields implicitly used by Unity are marked with an icon in the gutter.

• When Solution Wide Analysis is enabled, implicitly used fields and event functions are marked as in use. Fields are highlighted if they aren't accessed in your code.

  

• The plugin knows about all Unity based classes (MonoBehaviour, ScriptableObject, EditorWindow, etc.) and their event functions via analysis of the Unity API surface and documentation.

• Support for Unity API versions 5.2 - 5.5.

• Alt+Insert on Unity based classes to generate event functions methods via GUI.

  

• Generate also available from Alt+Enter context menu on Unity based classes.

• Auto complete will suggest event function names when declaring methods in Unity based classes, and expand to include method signature. Simply start typing an event function within a class deriving from a known Unity class, such as MonoBehaviour.

  

• Descriptions for event functions and parameters in Unity based classes are shown in tooltips and QuickDoc. To show the information in tooltips, ReSharper's "Colour identifiers" and "Replace Visual Studio tooltips" setting must be enabled (search for them in settings). Alternatively, use the excellent Enhanced Tooltip plugin.

  

• "Read more" in QuickDoc will navigate to the Unity API documentation, locally if available, or via the Unity website.

• Code completion, find usages and rename support for string literals in MonoBehaviour.Invoke, IsInvoking, InvokeRepeating and CancelInvoke. Also supports StartCoroutine and StopCoroutine.

  

• Inspection and Quick Fix to use CompareTag instead of string comparisons.

  

• Suppress naming consistency warnings for known Unity event functions. E.g. ReSharper no longer suggests that AnimatorIK be renamed to AnimatorIk.

• Disables the Assets and Assets\Scripts folders from being considered as "namespace providers". This means ReSharper will no longer suggest to include Assets or Scripts in the namespace of your code.

• Automatically sets correct C# language version, if not already specified in .csproj - ReSharper will no longer suggest code fixes that won't compile! Supports the default C# 4 compiler, Unity 5.5's optional C# 6 compiler and the C# 6/7.0 compiler in the CSharp60Support plugin.

• Support for UnityEngine.Color and UnityEngine.Color32. The colour is highlighted, and hitting Alt+Enter will open the colour palette editor to modify the colour. Also supports named colours and Color.HSVToRGB.

  

• External annotations to mark items as implicitly used, assertion methods and also provide string formatting assistance for logging methods.

Please feel free to suggest new features in the issues!

To install into ReSharper:

• Use ReSharper's Extension Manager (ReSharper → Extension Manager), search for "Unity" and install. Restart, and it'll just start working.

To install into Rider:

• Install from the "featured plugins" page of the welcome screen.
• Or, go to the Plugins settings page and install from there.

Please watch the repo or follow @citizenmatt and @slavikt on twitter for updates.

There is no roadmap as such. I am not a Unity developer, so do not know what the common pain points are. If you'd like to suggest a feature, please raise an issue.
