I was checking 2nd edition of Professional ASP.NET MVC and realized EF replaced LINQ to SQL. I am familiar to LINQ to SQL from the first book but I know nothing about EF. Anyway while reading the code, it seems like nothing has changed except the name. Same old repository, same old functions. I did a little research. I know LINQ is not...

Everything works beautifully if I'm debugging under web.dev (ie. in Visual Studio [2010]) but as soon as I try and run this under IIS7[.5] the debugger fails to attach.

But with VB, the only way I've found to use these features is with the old Option Strict Off trick that's been in...
