C# SDK

Morphir.SDK.CSharp is an independent net10.0 runtime package. It uses the BCL and System.Collections.Immutable, with no FSharp.Core, Morphir compiler, model, CLI or Roslyn dependency. Existing Morphir.SDK consumers remain unchanged.

Install the package version published for your application, then use the Morphir.SDK.CSharp namespace. Both C#14 and C#15 consumers use the same API. The SDK does not require C#15 union syntax or a source generator.

using Morphir.SDK.CSharp;

var optional = Maybe<int>.Just(7).Map(x => Basics.Add(x, 1));
var result = Result<string, int>.Ok(7)
    .AndThen(x => x > 0
        ? Result<string, int>.Ok(x)
        : Result<string, int>.Err("negative"));
var old = Dict<string, int>.Singleton("a", 1, MorphirComparers.String);
var updated = old.Insert("b", 2);
// old still contains only a; updated enumerates a then b.

Use the API guide for constructors, immutable collections and error behavior. The compatibility guide describes the bounded contract, compiler profiles and runtime publication checks.
