AutoMapper.FindUsage for Rider and ReSharper

Build and Publish Rider ReSharper

AutoMapper.FindUsage is a plugin for JetBrains Rider and ReSharper that provides seamless navigation between DTOs and Models based on your AutoMapper configurations.

Features

  • Find Usages: Deep integration with the standard Find Usages action in Rider and ReSharper.
  • Quick Navigation: Seamlessly jump between source and destination properties.
  • Fluent API Support: Automatically recognizes mappings configured via CreateMap<TSource, TDest>().
  • Bidirectional Mapping: Full support for .ReverseMap(). Navigation from Destination to Source always works, while Source to Destination navigation is available when a reverse mapping is defined.
  • Smart Grouping: Mappings are grouped by type in the Find Results window for properties with multiple sources or destinations.

Usage

  1. Open a C# file containing a class used in AutoMapper mappings.
  2. Place the caret on the set or init accessor of a property.
  3. Run Find Usages action.
  4. View the search result for source properties or jump to the corresponding member.

Find Usages Demo

Supported Configurations

The plugin analyzes your codebase to find various mapping patterns:

// Standard mapping (Destination -> Source navigation)
CreateMap<User, UserDto>();

// Reverse mapping support (Bidirectional navigation)
CreateMap<Order, OrderDto>().ReverseMap();

// Support for init accessors
public class UserDto { public string Name { get; init; } }

Installation

You can install the plugin directly from the JetBrains Marketplace.

Development

To test the plugin in a sandbox environment:

  1. Build the .NET part:

    ./gradlew compileDotNet

    (On Windows, use .\gradlew.bat compileDotNet)

  2. Launch Rider with the plugin:

    ./gradlew runIde

    (On Windows, use .\gradlew.bat runIde) This will start an experimental instance of Rider with the plugin installed.

  3. Verify functionality: Open any solution with AutoMapper configurations and test the Find Usages action.
