AutoMapper.FindUsage for Rider and 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 Results window:

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.
