Cannot use 'this' in member initializer?

Question

Is this legal? Does it contain a hidden bug or flaw? Visual studio does not give any errors or warnings but ReSharper does:

/// 

/// immutable         


        

Answer 1

I'm pretty sure I've heard that this is a compiler bug, fixed in the next release. I'm just firing up my 4.0 VM, with a simpler test-case:

class Foo {
    public Foo() : this(delegate { this.Bar(); }) { }
    public Foo(Action foo) {}
    public void Bar() {}
}

works in VS2008, but in VS2010:

Error 1 Keyword 'this' is not available in the current context
