KB 831150 - View-state is invalid for this page" error message does not provide sufficient information to troubleshoot the issue

Most asp.net developers have one time or the other ran into messing up their view-state causing asp.net to throw the "View-state is invalid for this page" exception. After scratching their heads for a while and figuring out what is screwing their view-state they'll probably fix it in the end. But wouldn't it be much nicer if the exception contained some info about what actually wrong ? Lo and behold they newly released KB : Microsoft Knowledge Base Article - 831150 , INFO: "View state is invalid for this page" error message does not provide sufficient information to troubleshoot the issue. Unfortunately you have to contact Microsoft to get the hot-fix, but it probably will be included in the next service pack

Microsoft windows 2000 and NT source code leaks !

REDMOND, Wash., Feb. 12, 2004 -- On Thursday, Microsoft became aware that portions of the Microsoft Windows 2000 and Windows NT 4.0 source code were illegally made available on the Internet. It’s illegal for third parties to post Microsoft source code, and we take such activity very seriously.

Oops.

Hiring tips ?

Our small 6 person company is looking to expand and hire another .net developer, and We've been interviewing some candidates. What should we look for in a candidate, overall .net knowledge, strong overall CS skills, experience, knowledge of MS products, enthusiasm ?

Any tips ?

HttpContext.Current

System.Web.HttpContext Context = System.Web.HttpContext.Current; !

For a while every time I created a function that looked something up in cache or Context.Items, I used to pass the Context object as a parameter to do the lookup on.  Then I hadn't discovered the System.Web.HttpContext.Current object, it returns a reference to the currently executing HttpContext. Why hadn't someone told me about this one ! ;)

Oh, the joy of refactoring !
