As the owner of the VB.Net portion of the overall debugging experience, I frequently hear the request from customers to add LINQ support into the Watch / Immediate and Locals window. Virtually every other type of expression is available in the debugger windows so why leave one of the most popular ones...

Script blocks are a concise way of representing an expression or statement group in Powershell.  It’s the C#/F#/VB lambda equivalent for PowerShell.  One difference between C#/F#/VB lambda expressions and a scriptblock is the lack of lexical closures (otherwise known as variable capturing)...

For previous articles in this series please see ... Part 1: Introduction Part 2: Method Calls Part 3: Scope Part 4: Variable Lifetime Part 5: Looping As powerful as closures are in the language they do have a few limitations. We worked hard in Orcas to put as few limitations in Orcas as possible. Below...

For previous articles in the series please see Part 1: Introduction Part 2: Method Calls Part 3: Scope Part 4: Variable Lifetime Once again sorry for the long delay between posts. Looping structures can cause unintended consequences when used with Lambda expressions. The problem occurs because lambda...

For previous articles in this series please see Part 1: Introduction Part 2: Method Calls Part 3: Scope Sorry for the long delay between posts here. We're getting Orcas out the door and getting this series completed takes a back door to shipping. Originally I wanted to talk about looping structures next...

For previous articles in this series please see Part 1: Introduction Part 2: Method Calls Thus far in the series we've only lifted variables that are declared in the same block/scope. What happens if we lift variables in different scope? The answer is that one closure class will be created for every...

For previous articles in this series, please see Part 1 - The basics This part of the series will focus on how method calls are handled in closures. As stated in the previous article, the purpose of closures is to allow all operations inside a lambda or query expression that would normally be available...

One of the features I implemented for VB 9.0 is lexical closure support. This a great addition to the VB language and I wanted to do a series of blog posts to describe this feature and how it will impact your code. Lexical Closures (more often referred to as simply Closures) are the underpinnings...
