In September 2019, Microsoft released .Net Core 3. This version of .NET Core added support for Windows desktop application development and also included substantial performance improvements throughout BCL. This version was followed by .NET Core 3.1 in December 2019.

However, past .Net Core 3.1, Microsoft dropped the idea of further upgrades and instead worked towards launching a unified .NET platform that would combine the benefits of .NET Core with the .Net Framework. This unified platform was launched on November 10, 2020, as .NET 5.0. There was no more 'Core' in the brand name for the new platform. According to Microsoft, the shorter name isimplifiesfor ease of use and communicates that .NET 5.0 has uniform capabilities and behaviors across your desktop, laptop, and cloud instances. With .NET 5.0, developers' code and project files will look and feel the same regardless of which type of app they create. Developers will get access to the same run-time, API, and language capabilities with each app. Another of the goals behind the creation of .NET was to broaden the capabilities of .NET by merging the best of .NET Core, .NET Framework, Xamarin, and Mono.

It is estimated .NET 5.0 has approximately 20% performance increase over .NET Core 3.1 and .NET 5.0 server performance is 60% faster than .NET Core 3.1

.NET 5.0 client performance is 230%% faster than .NET Core 3.1

.NET 5.0 supports all Visual Studio versions released after Visual Studio 2017. Visual Studio 2019 supports .NET 5.0 and is also compatible with C# 9.0. Figure 14.7 depicts the architecture of the .NET 5.0 platform.

.NET 5.0 includes library enhancements as well as language improvements. For developers, the biggest advantage of .NET 5.0 is that they are now able to use a single set of APIs, languages, and tools to target a wide range of application types, such as mobile, cloud, desktop, and loT.

Through .NET 5.0, NET apps can run natively on Windows Arm64, which in turn leads to better performance.

When developers create or build applications, in the end, they deploy them for end users to the Deployment target may be a Web server, a cloud service, a command line, or a client machine. .NET 5.0 facilitates easier deployment. One of the ways it does this is by supporting the ClickOnce tool which has been a popular .NET Framework deployment option for many years. This tool can be used for .NET 5.0 Windows apps as well. It helps developers create Windows-based applications that are self-updating and can be installed and executed with minimal user interaction. It is recommended that for all new development henceforth, .NET 5.0 or higher versions should be used.
