Catch up with what’s latest in the Fiddler family of products on .NET Rocks.
Carl Franklin and Richard Campbell host .NET Rocks—1800+ podcast episodes later, .NET Rocks continues to educate and entertain developers on latest technology trends. The most recent .NET Rocks show dived into all things Fiddler—the history, evolution and what lies ahead for the popular network debugging tool.
To say .NET Rocks has been one of the most popular podcasts would be an understatement—so many developers grew up with .NET Rocks. The late night drives from a customer site/user group meeting, the early morning walks/jogs, the working lunches—so many of us have had .NET Rocks playing in our ears over the years. With production always being top notch, .NET Rocks has informed, educated and entertained developers for the past two decades. Cheers, Carl and Richard, for years of knowledge bites and chuckles.
A recent .NET Rocks episode had Rosen Vladimirov and yours truly on to talk about Fiddler—another thing that so many developers have grown up with. From humble beginnings, Fiddler has evolved into a big family of products serving various users/teams with differing needs. While the popularity of Fiddler has meant developers have had Fiddler as a default part of their development toolset, recent Fiddler updates embrace latest network technologies and open up the tooling to QA/Support/end users. The .NET Rocks show was a great discussion on Fiddler basics to the current reality and what the future holds for a beloved tool—give it a listen, people.
