EDITORIAL A lot of the conversations I have with Melanie about creativity and collaboration center around many non-tech fields. Every creative endeavor shares some a common DNA and by examining other fields not related to your own, you might find newer ways of thinking. At a minimum, you’ll likely learn something you don’t know. That’s a win/win, right? Well, this particular conversation was focused on one creative field: music. We talked about how COVID changed the way musicians were forced to change their collaborative process during the pandemic. Before COVID, I was taking guitar lessons. My teacher came to my house twice a month for an in-person session where he taught me the foundations of guitar playing, including scales, chords, and, what was probably the most difficult aspect for me,…

My day job is writing a database engine named RavenDB. My preferred language to code in is C#. Those two facts tend to cause glitches in some people’s minds. How can you write a database engine, which is all about low-level system programming, in a high-level language such as C#? How much performance are you leaving on the table by not choosing a proper system-level language, such as C++ or Rust? It turns out that there isn’t a conflict between the two. You can write high-performance code in C# that matches or beats the performance of native code. The best part is that you can achieve that while retaining many of the advantages that C# offers in the first place. C# has a lot of expressiveness and high-level concepts, but…

As we continue our celebration of “30 years of CODE Group,” we travel forward five years from last issue’s installment of “the Antique CODE Show” and look at our industry, and the world in general, 25 years ago (or so). The late 90s were an interesting time for our industry. Compared to five years earlier, the internet had rapidly become mainstream. Although hardly anyone outside the software industry had heard of it in 1993, hardly anyone had not heard of it by 1998. Markus, the dynamic founder of CODE Group and CODE Magazine’s publisher, is a celebrated Microsoft RD (Regional Director) and multi-award-winning MVP (Most Valuable Professional). A prolific coder, he’s influenced and advised top Fortune 500 companies and has been a Microsoft contractor, including on the Visual Studio team.…

In my previous article in the July/August 2023 issue of CODE Magazine (https://www.codemag.com/Article/2307041/An-Introduction-to-OpenAI-Services), I gave you an introduction to OpenAI services. One of the topics I discussed was how to use LangChain to build an LLM-based application. LangChain is a framework designed to simplify the creation of applications using Large Language Models. It “chains” together various components to create compelling AI applications that can query vast amounts of up-to-date data. Wei-Meng Lee is a technologist and founder of Developer Learning Solutions (http://www.learn2develop.net), a technology company specializing in hands-on training on the latest technologies. Wei-Meng has many years of training experience and his training courses place special emphasis on the learning-by-doing approach. His hands-on approach to learning programming makes understanding the subject much easier than reading books, tutorials, and documentation. His…

.NET Core has been a great ride for all of us building web- and cloud-driven apps, but managing distributed apps made for cloud native has been a mishmash of different tools. That’s about to change. Seeing a problem in how large microservice architectures are deployed and managed, the ASP.NET team has taken a big swing with a solution that should help most .NET developers think about microservices and distributed applications without the dread many of us have had. Shawn Wildermuth has been tinkering with computers and software since he got a Vic-20 back in the early ’80s. As a Microsoft MVP since 2003, he’s also involved with Microsoft as an ASP. NET Insider and ClientDev Insider. He’s the author of over twenty Pluralsight courses, written eight books, an international conference…

In a previous article in CODE Magazine, https://www.codemag.com/Article/2209021/FIDO2-and-WebAuthn, I talked about FIDO2 and WebAuthn. Look, passwords suck, but finally, as an industry, we’re getting behind getting rid of them for real. The FIDO2 standard bakes in enough capabilities to completely eliminate passwords, and passkeys offer the convenience to be a great password replacement. Yes, password stealing is going to be history and along with it, things such as phishing. This safety will gradually be so completely built across the internet that our grandmothers will feel comfortable using it. Of course, security is a game of cat and mouse. The threats will just move elsewhere, like hacking into back-end systems, social engineering, etc. Sahil Malik is a Microsoft MVP, INETA speaker, a .NET author, consultant, and trainer. Sahil loves interacting with…

Mike is the CEO of EPS’s Houston office and a skilled .NET developer. Mike excels at evaluating business requirements and turning them into results from development teams. He’s been the Project Lead on many projects at EPS and promotes the use of modern best practices, such as the Agile development paradigm, use of design patterns, and test-drive and test-first development. Before coming to EPS, Mike was a business owner developing a high-profile software business in the leisure industry. He grew the business from two employees to over 30 before selling the company and looking for new challenges. Implementation experience includes .NET, SQL Server, Windows Azure, Microsoft Surface, and Visual FoxPro. So I promised a follow-up article that explored the code. Since then, SK went into beta and then Release Candidate,…

In the realm of enterprise applications, a deep understanding of distributed caching intricacies and adherence to best practices are essential to building enterprise applications that are scalable and high performant. You can choose from the popular distributed caching frameworks, such as Memcache, NCache, Redis, and Hazelcast. In this article, I'll discuss distributed caching, its benefits and use cases, and then teach you how to implement it in ASP.NET Core. If you’re to work with the code examples discussed in this article, you need the following installed in your system: • Visual Studio 2022 • .NET 8.0 • ASP.NET 8.0 Runtime Joydip Kanjilal is an MVP (2007-2012), software architect, author, and speaker with more than 20 years of experience. He has more than 16 years of experience in Microsoft .NET…
