.NET Core 3.0, Microsoft 
Let's discuss in detail features of the building and future of .NET Core and .NET Framework:
The company states that .NET Core 3.0 addresses three scenarios in the .NET Framework developer community including;
Side-by-side versions of .NET that support WinForms and WPF: This is the one version of .NET Framework on a machine. When a user updates the .NET Framework there will be a risk that a security fix, new API, or bug fix can break applications on the machine. But with the user uses the .NET Core, this problem can be solved by allowing multiple versions of .NET Core on the same machine.
Embed .NET directly into an application: The .NET Core helps in the framework as part of the users' application. This enables the users' to take advantage of its latest version, APIs, and features without having to wait for the framework to be installed.
Take advantage of .NET Core features: The .NET Core is the open source and fast-moving version of .NET. It also has the feature to enables the user to introduce new innovative BCL (Base Class Library) and APIs improvements without the risk of breaking compatibility.
The company also states that the .NET Framework 4.8 addresses three scenarios and its .NET Framework developer community has also asked for, including:
Modern browser and modern media control: The .NET desktop applications use Windows Media Player and Internet Explorer for showing HTML and playing media files. So the user can take advantages of Microsoft Edge and newer media players for supporting the latest standards.
Access to touch and UWP Controls: UWP (Universal Windows Platform) has new controls taken from the latest Windows features and touch displays. The same features are also included in the WinForms and WPF.
High DPI improvements: The resolution of displays is steadily increasing to 4K and 8K resolutions.
Well, the .NET Framework is the implementation of .NET installed on over one billion machines and thus needs to remain as compatible as possible. It helps the .NET Core for fixing security and bug fixes that can cause breaks in applications. The .NET Framework always supports the latest networking protocols, Windows features, and security standards.
We can also define the .NET Core as the open source, fast-moving, and cross-platform version of the .NET. The .NET Core have the new language and APIs features that the .NET Framework cannot.
If the user has existing .NET Framework applications, he/she should not feel pressured to move to .NET Core because both the .NET Framework and .NET Core will move forward.
