Micro library inspired by F# single case discriminated unions. Create primitive domain concepts in C# with one line.

Micro library inspired by F# single case discirminated unions.

Create primitive domain concepts in C# with one line.

class Age : CaseOf<int, Age> {}

Pass around instances worry free, they are immutable and implement value based equality.

var hisAge = Age.New(23);
var herAge = Age.New(23);

Assert.IsTrue(herAge.Equals(hisAge));

Implicit downcasting to wrapped typed.

int integerHisAge = hisAge;
int integerHerAge = herAge.Value;

Assert.IsTrue(integerHisAge.Equals(integerHerAge));

Create Action<> or Func<> delegates that are descriptive.

class Username : CaseOf<string, Username> {}
class Email : CaseOf<string, Email> {}

Action<Username, Email> register = (name, email) => { /* .... */ }

Available on Nuget or direct embedding (just copy CaseOf.cs file to your project)
