Why Visual Studio IntelliSense is not working here?

Question

Is it not working only for me or for everyone? It's not working everytime I write 'foreach' block inside lambda (dot after Enumerable):

Action t = ()=>
{
    foreach (var item in Enumerable.)
    {

    }
};

Any idea why it's not working in such cases?

I have VS 2010 SP1

update: It's not about Enumerable, it's about any object. I can try to write new object(). and have the same problem.

Answer 1

I can reproduce the bug with VS2010 SP1 and a brand new project:

class Program
{
    static void Main(string[] args)
    {
        Action t = () =>
        {
            foreach (var item in Enumerable.Range(1, 10))
            {
            }
        };
    }
}

Delete ".Range(1, 10)" and type "." and you should see Intellisense choices but there are none. But if you assign the expression to a temporary variable it works as expected. Follow Hans advice and file a bug report.

Answer 2

Even if you type the open and close parantheses for foreach, you can get intellisense. For intellisense to work, you need to be typing in front of a white space.

For example: foreach then () and then go back into () and start typing var x in ... no intellisense! But, foreach then ( ) with a space and then go back into ( ) and start typing right after the (... now you get intellisense.

This is the behavior with C# settings. Not sure about settings for other languages.
