I believe named parameters are for version 4. In addition, the args are not between ( and ), so it cannot be a method/constructor call
( see http://blogs.windowsclient.net/alesrosina/archive/2008/12/02/new-stuff-in-c-4-0.aspx under optional parameters)

Looks like an object/collection initializer (http://msdn.microsoft.com/en-us/library/bb308966.aspx#csharp3.0overview_topic13 - see 26.4 Object and Collection Initializers)


I'd say it is the shorthand for

var xx = new ComparisonContract<Foo>() ;
xx.ImplementsOperatorOverloads = true ;
xx. EquivalenceClasses =  {
     { new Foo(1) },    // What is this?
      { new Foo(2) },
      { new Foo(3) }
   }

>>>  { // What is this?

>>>    EquivalenceClasses =

>>>      { new Foo(1) },    // What is this?
