MappingGenerator is a Roslyn-based code fix provider for C# that generates object-to-object mapping code at design time, serving as a compile-time alternative to AutoMapper. It ships as a Visual Studio VSIX extension or NuGet package and also works with JetBrains Rider.

Use cases

• generate mapping method implementations automatically in C#
• design-time alternative to AutoMapper
• generate full mapper classes from method signatures
• generate mapping lambdas for LINQ Select calls
• scaffold object initializers and method invocations
• implement object cloning code in Visual Studio

When to choose

• you want explicit, compile-time-checked mapping code instead of reflection-based AutoMapper
• you work in Visual Studio or Rider with C# and want one-keystroke mapping generation
• you need scaffolding for object initializers and method invocations

When to avoid

• you need actively maintained open-source software - the FOSS version is archived and development moved to a commercial product
• you don't use Visual Studio, Rider, or other Roslyn-based tooling
• you want runtime mapping configuration like AutoMapper's profiles
