Why doesn't C# have a synchronized keyword?

Posted at 17:40 on 27 February 2006

In Java you can mark a class method as a critical section, i.e. it will only be executed by one thread at a time, by using the synchronized keyword:

synchronized void myMethod()
{
  doSomething();
}

In C# you have to type in this ghastly (and rather obscure) mouthful:

using System.Runtime.CompilerServices;

[MethodImpl(MethodImplOptions.Synchronized)]
void MyMethod()
{
    DoSomething();
}

Why can't we have a synchronized keyword in C# for this like in Java?
