Closures and Object Lifetime in C# and Visual Basic
C# 2 and the yet to be released VB 9 allow developers to reference local variables in anonymous functions. When an anonymous function 'closes over' a variable, the local variable is promoted to an instance variable and stored in an object called a closure. This allows the variable to exist long after the method call that created it has been completed, but can cause some unexpected side effects.

Microsoft's GUI toolkits tend to encourage developers to tightly couple business logic with presentation. Comparing the original VB and ASP or WinForms and ASP.Net, one sees very little change in this regard.

New Best Practices for Working with Date/Time Values
A common problem with programming languages, including those of .NET, is the lack of decent time zone support. Too often developers pretend that time zones do not exist at all rather than take the time and effort to get them right. Microsoft seeks to change this for .NET programmers by introducing the TimeZoneInfo and DateTimeOffset classes.

Microsoft and Agile - Divergent Agendas?
Martin Fowler has questioned Microsoft's grip on leading-edge developers. MS has threatened one developer with legal action over his TestDriven.Net extension for VisualStudio Express, and MS development of an incompatible rival to NUnit has alienated many developers.
