Microsoft announces the release of .NET 7 Preview 3

Recently, Microsoft announced that the third preview of .NET 7 is now available. This release brings users enhancements to observability, startup times, codegen, GC regions, Native AOT compilation, and more. 

Interested users can download .NET 7 Preview 3 for Windows, macOS, and Linux. It has also been tested with Visual Studio 17.2 Preview 3. Microsoft recommends using the preview channel builds to try .NET 7 with Visual Studio family products.

With Native AOT, pre-compilation is brought to .NET desktop client and server scenarios. According to Microsoft, this addition does not serve to replace existing technology, but rather to offer a new set of capabilities that allows users access to new form factors. 

This preview release also adds support for new cloud native OpenTelemetry specifications. This includes specification updates #988 and #1708 that make the trace state mutable for samplers. 

With this, the latest Managed Extensibility Framework also received a slight update in order to align with the previous version APIs. With the new APIs, a single object instance can be added to the System.Composition.Hosting container. 

Startup times are also improved with Write-Xor-Execute enabled. This change also resulted in state performance improvements in some microbenchmarks and a few ASP.Net Benchmarks even when Write-Xor-Execute was not enabled.

In large part, Microsoft credits community contributors for the multitude of optimizations and bug fixes that are included in .NET 7 Preview 3. These include fixes made to code generation and just-in time compilation.

Difference between Web Designer and Web Developer Neeraj Mishra The Crazy Programmer

Have you ever wondered about the distinctions between web developers’ and web designers’ duties and obligations? You’re not alone! Many people have trouble distinguishing between these two. Although they collaborate to publish new websites on the internet, web developers and web designers play very different roles. To put these job possibilities into perspective, consider the construction of a house. To create a vision for the house, including the visual components, the space planning and layout, the materials, and the overall appearance and sense of the space, you need an architect. That said, to translate an idea into a building, you need construction professionals to take those architectural drawings and put them into practice. Image Source In a similar vein, web development and design work together to create websites. Let’s examine the major responsibilities and distinctions between web developers and web designers. Let’s get going, shall we? What Does a Web Designer Do?

2022: The year of hybrid work

Remote work was once considered a luxury to many, but in 2020, it became a necessity for a large portion of the workforce, as the scary and unknown COVID-19 virus sickened and even took the lives of so many people around the world.  Some workers were able to thrive in a remote setting, while others felt isolated and struggled to keep up a balance between their work and home lives. Last year saw the availability of life-saving vaccines, so companies were able to start having the conversation about what to do next. Should they keep everyone remote? Should they go back to working in the office full time? Or should they do something in between? Enter hybrid work, which offers a mix of the two. A Fall 2021 study conducted by Google revealed that over 75% of survey respondents expect hybrid work to become a standard practice within their organization within the next three years.  Thus, two years after the world abruptly shifted to widespread adoption of remote work, we are declaring 20
