RG.ZeroMapper

RG.ZeroMapper is a Zero boilerplate (kind of) C# object mapper.

Bar b = new { X = 1 }; // Auto implicit cast Foo f = b; // The only boilerplate: Mark destination class as partial partial class Foo { public int X; public string S; } partial class Bar { // same name, but it's a property instead of a field public int X { get; set; } // same name, different name casing public string s; }

RG.ZeroMapper.Structural

RG.ZeroMapper.Structural leverages RG.ZeroMapper to enable structural typing in your C# code:

class A { public int X; public int Y; } class B { public int Y; public int Z; } record C() : Constant(1); partial class D : Intersect<A, B, C> { // D implicitly contains Y } partial class E : Union<A, B, C> { // E implicitly contains X, Y, Z // E can be implicitly cast to int with the value of 1 // E can be implicitly cast from int as long as the value is 1 // E can be implicitly cast to C? // Unions can only contain 1 constant value of each value type } partial class F : OneOf<A, B, C> { // F is a discriminated union // F can be cast into A?, B?, or C? // Discriminated unions don't inherit any property }
