Everything You Need to Know About ASP.NET Core 3.0

Microsoft keeps on pushing tons of updates and changes to .NET Core over the years. Each new update brings a plethora of features over from its more mature and feature-rich sibling, .NET Framework. However, if you ask the developer community, the gap between features has remained quite large for a major number of scenarios, leaving them waiting and waiting for more to play and create with.

Now that .NET Core 3.0 has arrived, there is a big chance that Microsoft may have a chance to win hearts and minds once and for all. Companies may now have a chance to hire ASP.NET developers who are happy and excited to work in their forte.

One of the biggest show-stoppers which Microsoft pulled off was to remove from the equation with the launch of .NET Core 3.0 is support for desktop applications, which is finally available in the new framework.

  • The .NET Core 3.0 is has been battle-tested by being hosted for months at dot.net and on Bing.com. Other expert teams from Microsoft will soon start deploying large workloads on .NET Core 3.0 in production.
  • The .NET Core 3.0 now has extended support for Windows Desktop apps that are built with WPF and Windows Forms. Those involved in Windows development can now take advantage of .NET Core platform features, including flexible framework deployments (such as self-contained or side-by-side), better runtime performance for selected classes of APIs (such as I/O and networking), and new updated language features in C# 8.
  • In the latest version, ASP.NET SignalR simplifies the process of adding real-time web functionality to the existing applications. In .NET Core 3.0, Azure SignalR Service backs OnConnected and OnDisconnected event handlers with Event Grid.
  • SignalR clients have AutoReconnect() method enabled to allow automatic reconnection. Microsoft has added improved policy support where users can control the hub method name and individual user access. They have also provided added client-to-server streaming support.
  • Increased support for the import and export of asymmetric public and private keys from standard formats, with no need for X.509 certificates. Additional support for AES-GCM and AES-CCM ciphers.
  • The latest version had hardening for Docker, enabling .Net applications to work efficiently and predictably in containers. For the thread pool and garbage collector, we have updated container which has been been configured for limited memory or CPU. From now the Docker images for .Net Core will be smaller, especially the SDK image.
  • In order to keep up with the rising pace of emerging technologies, Microsoft has added Raspberry Pi and ARM chips support to enable IoT development, including with the remote Visual Studio debugger. You will now be able to deploy apps which listen to sensors, and print messages or images on a display by using the new GPIO APIs.
  • Now that we have Nullable Reference Types, C# takes a big step toward slashing off null reference exceptions as a source of program failures. We also have support for Asynchronous Streams which makes it easy to consume and produce real-time streams of data efficiently.
  • Now, Switch Expressions and Recursive Patterns are able to allow for elegant conditional logic over the structure of objects, and Range Expressions simplify slicing operations on arrays, strings and spans.?

Conclusion

..Net Core 3.1 will follow .NET Core 3.0. The 3.1 version is a long-term support (LTS) release planned for November 2019. Also, moving forward Microsoft will consolidate .Net development around .Net 5 next year which will end separate releases of .Net Framework and .Net Core. The latest version is good news for both, a freelance developer as well an ASP.NET development company, since more and more number of businesses will opt for .NET development in future.
