Compiling a .NET 3.5 project and running on a .NET 2.0 machine
For those that are still curious after my previous post about using C# 3.0 features in .NET 2.0. You can compile any .NET Framework 3.5 project and run it in a .NET Framework 2.0 environment (read, no .NET Framework 3.5 installed) without any problems… as long as there are no dependencies to the .NET 3.5 assemblies!
Create a new Console Application under .NET Framework 3.5. Check your references, System.Core will be automatically added to the project. This is a .NET Framework 3.5 assembly. Remove it.
Now add a single Console.WriteLine as follows:
using System;
using System.Collections.Generic;
using System.Text;
namespace FrameWork35ConsoleApp
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine(“Hello world from a .NET 3.5 application.”);
}
}
}
Compile it and copy the executable to a .NET Framework 2.0 machine. Again, one without .NET Framework 3.5 installed.
Run the executable and watch the result.

3.5 is based on 3.0 which is based on 2.0… try to use WCF in the console application and run it on framework 2.0… outch!
