VS2010 C# intellisense crash - reproduce and confirm

Mike Nakis

Can anyone please reproduce and confirm this? Create a new project, make it a C# console application, use all default settings. Open the generated "Program.cs" file and replace its contents with the following:

namespace ConsoleApplication1
{
public class ParameterAttribute: System.Attribute
{
}

class Program
{
    \[Parameter( name:"name1" )\]
    int Field1;

    static void Main( string\[\] args )
    {
    }
}

}

I know, there is an error in the code. Please bear with me. Just do the following: move the mouse pointer over the word "name" in the code, and click. In other words, place the caret in "name". Does anything happen? Cause when I do that, Visual Studio 2010 disappears without even saying good bye. It panic-quits. More information: I am on Win7 x64 SP1, and this is what I get from Visual Studio / Help / About / Copy Info:

Ohhhhhhhh hope you are wearing your asbestos pants... this looks suspiciously like a programming question in the lounge!!

No, it is not a programming question, it is an incitement for a technical discussion, which, according to the launge rules, is not only allowed, but encouraged even.

There is a forum for Visual Studio questions, and this is not it.

Use the best guess

Uh-oh, I did not see that. In this case I hope someone will move it there.

Thank you very much. It looks like I should be installing all those updates!

Confirmed. The space before "name" was crucial and I had to edit it back in, so you may get some false negatives.

Harold aptroot wrote further down: "Confirmed. The space before "name" was crucial and I had to edit it back in, so you may get some false negatives." So, did you try it with, or without a space before "name" ?

Mike Nakis

To me it happens regardless of whether I put a space before "name".

OriginalGriff

Copy 'n' paste from your original post, so the space would have been there.

OriginalGriff

Interesting one for you: I just tried it again, with a new project, pasted your code in. The space disappeared (I assume intellisense autoformatted it out when I pasted to fit my settings) Crashed this time.

Update: installing all the hotfixes & stuff from windows update did *not* solve the problem.
