DotNetMapper

NuGet CI

A zero-config object mapper for .NET with one method. It copies public properties that have the same name and the same type into a new object. A bundled source generator turns each call into the code you would write by hand, so it runs at hand-written speed and is NativeAOT safe.

dotnet add package DotNetMapper

Requires .NET 10.

Usage

using DotNetMapper;

UserDto dto = Mapper.Map<UserEntity, UserDto>(entity);

No attributes, profiles or configuration. Properties without a match are ignored, values are assigned rather than cloned, and types must be identical: int is not copied to long.

Performance

Mapping a 10-property class on .NET 10. Lower is better.

Library Mean vs hand-written Allocated
Hand-written 13.5 ns 1.00 136 B
DotNetMapper 2.0 12.7 ns 0.94 136 B
Mapperly 4.3 13.8 ns 1.03 136 B
Mapster 10.0 33.9 ns 2.52 208 B
AutoMapper 16.2 61.5 ns 4.57 224 B
TinyMapper 3.0 62.0 ns 4.61 272 B
AgileMapper 1.8 242.4 ns 18.01 456 B

DotNetMapper and Mapperly both emit the hand-written code, so they are equal within noise. The benchmarks have the full tables, setup and how to run them.

The wiki has every rule with examples:

When to use something else

If you need renaming, type conversion, flattening or configuration, use Mapperly. DotNetMapper is deliberately the one-method case.
