his is the last preview for .NET 7 and the next version will be our first release candidate (RC). 

Unreal Engine 4 is now available to everyone for free, and all future updates will be free!  

In this article, I will share seven generative AI prompts that I have created and use as a .NET developer. These prompts can help us work more efficiently, tackle common problems, and improve our projects.

My guess is that this could be part of a long-term strategy to retire the full .NET Framework , rather than bringing any real value to .NET Core or desktop applications. 

Did you know that DotVVM can be used to incrementally modernize old ASP.NET Web Forms applications and lift them to .NET Core? It is much easier than doing a full rewrite, and the application can be deployed at any time during the entire process.

• Install DotVVM NuGet package in your Web Forms site
• Create a DotVVM master page using the same CSS
• Start converting ASPX pages to DotHTML syntax, one at a time
• When all the Web Forms pages are gone, change your CSPROJ to use .NET Core 

.NET Framework 4.5.2, 4.6, and 4.6.1 will reach End of Support on Apr 26, 2022 - .NET Blog 

Lambda expressions (or lambda functions) are essentially blocks of code that can be assigned to variables, passed as an argument, or returned from a function call, in languages that support high-order (first-class) functions.

Today, we’re excited to introduce GitHub Package Registry, a package management service that makes it easy to publish public or private packages next to your source code.

GitHub Package Registry is fully integrated with GitHub, so you can use the same search, browsing, and management tools to find and publish packages as you do for your repositories. You can also use the same user and team permissions to manage code and packages together. GitHub Package Registry provides fast, reliable downloads backed by GitHub’s global CDN. And it supports familiar package management tools: JavaScript (npm), Java (Maven), Ruby (RubyGems), .NET (NuGet), and Docker images, with more to come.
