This article mainly shows you "what are the improvements of .NET Core 3.1", which is easy to understand and well organized. I hope it can help you solve your doubts. Let me lead you to study and learn this article "what are the improvements of .NET Core 3.1?"

The .NET Core 3.1 has been released, which is a small part of the fix and improvement of the .NET Core 3.0 released more than two months ago, the most important of which is that the .NET Core 3.1 is a long-term supported (LTS) version and will officially support it for three years.

The changes in .NET Core 3.1 focus on Blazor and Windows Desktop, two new features in .NET Core 3.0, including support for C++/CLI, which is already a regular requirement for developing Windows.

Windows Forms Controls Removal

The following Windows Forms controls have been removed in this release:

DataGrid

ToolBar

ContextMenu

Menu

MainMenu

MenuItem

Back in 2005, these controls were replaced by more powerful controls in the .NET Framework 2.0, which are not available in the Visual Studio Designer toolbox by default, and now officials have decided to remove them and focus only on the new ones.

The proposed alternatives are as follows:

Microsoft believes that as the Windows Forms designer project is further refined, these controls do not match the creation of modern applications and should never be part of the Windows Forms .NET Core version. The goal of such a major change is to continue to improve Windows Forms to achieve higher DPI, accessibility, and reliability, and to facilitate later updates.

C++/CLI

A new feature has been added in Visual Studio 2019 to create C++/CLI components that can be used with .NET Core 3.0 +.

This component adds several templates that you can use:

CLR Class Library (.NET Core)

CLR Empty Project (.NET Core)

C++/CLI only supports the Windows platform, developers need to install the "Desktop development with C++" workload and "C++/CLI support" components to use C++/CLI.

At the same time, Visual Studio 2019 has been released, which includes the .NET Core 3.1 update, which is necessary to use .NET Core 3.1 with Visual Studio. For Visual Studio 2019 users, it is officially recommended to update directly to 16.4 instead of downloading .NET Core 3.1 separately.
