Greetings fellow .NET enthusiasts and tech aficionados! With the highly-anticipated .NET Conf 2024 just around the corner, I find myself reflecting on how far we’ve come in the world of .NET development and what thrilling innovations are yet to come.

A Journey Through .NET

Let’s take a quick stroll down memory lane. My experience with .NET technologies dates back to 2002, when I first dipped my toes into the vast sea of possibilities offered by .NET. Over the years, I’ve seen it transform from a promising framework into a powerhouse that underpins countless applications worldwide. Every upgrade has brought something new and exciting, fueling my passion for staying on the cutting edge of technology.

Effortless integration and enhanced visibility with OpenTelemetry in Blazor WebAssembly

Challenges in observing WebAssembly applications

Observing WebAssembly applications presents unique challenges that stem from its design and execution environment. Unlike traditional web applications, where monitoring tools can hook directly into JavaScript and the Document Object Model (DOM), WebAssembly runs as binary code executed within the browser’s sandbox. This layer of abstraction complicates direct introspection, as traditional monitoring tools are not designed to interact with the lower-level operations of WebAssembly. The Bytecode Alliance plays a crucial role here, promoting standards and tools that aim to enhance the security and usability of WebAssembly, including better support for observability. Moreover, the performance characteristics of WebAssembly, which can closely approach native speeds, demand monitoring solutions that are both highly efficient and minimally invasive to avoid impacting the user experience. This creates a complex scenario for developers who need detailed visibility into their applications’ behavior without sacrificing performance.

Learn how to collect all the telemetry from the .NET Aspire eShop application and send it to an OpenTelemetry backend such as New Relic

.NET Aspire is the new kid on the block when it comes to an opinionated, cloud-ready stack for building observable, production-ready, distributed applications. Having a built-in dashboard for the monitoring data is nice during development. But how do you configure OpenTelemetry correctly to send it to an observability backend? This is what this blog post is all about. And you’ll also learn how to send custom attributes by leveraging OpenTelemetry SDKs.
