Passing F# With to C#

Program.cs

using System;
using Types;

namespace App {
	class Program {
		static void Main( string[] args ) {
			Tag testTag = new Tag( 1, "Original" );
			Console.WriteLine( "{0}: {1}", testTag.Id, testTag.Text );
			Tag newTag = testTag.With( nameof( testTag.Id ), 2 ).With( nameof( testTag.Text ), "New One" );
			Console.WriteLine( "{0}: {1}", newTag.Id, newTag.Text );
			Console.ReadKey();
		}
	}
}

Types.fs

namespace Types

type Tag =
  {
    Id:int;
    Text:string
  }

  member this.With( field:string, value:int ) = 
    match field with
    | "Id"    -> { this with Id = value }
    | _       -> this

  member this.With( field:string, value:string ) = 
    match field with
    | "Text"  -> { this with Text = value }
    | _       -> this

Slightly safer (usage, not implementation)
