RecSharp

RecSharp is an immutable record generator for .NET Immutable records are similiar to F#'s records or Scala's case classes, but can be used from C# safely.

Here is the sample record definition (You can found it in sample.rcs)

namespace Records {
    using System;

    record Test {
        Int32 Id;
        String Name;
		Nullable<Decimal> Amount;
    }
}

Generater class Test will have:

• getter-only properties
• constructor with parameters for properties initialization
• Copy() method with optional parameters
• IEquatable implementation
• overrides os Equals() and GetHashCode()
• == and != operators

External libraries can be referenced by command-line parameter or by the following syntax (which if useful for VS extension):

#ref System.Linq.dll;

Compile it with RecSharpC -i sample.rcs -o Records.dll and reference Records.dll to Your project. That's it!
