为什么两个 .NET Framework 4.7.2 项目的属性看起来不同？

Question

I have a solution with mostly C# Class Library (.NET Framework) projects. I have added a new project to the solution (called Training ) for same the Target Framework (ie .NET Framework 4.7.2). But as shown in the screenshot below, if I compare the properties of an old project (called Programming ) wrt the new project (called Training ) then, the different structure of the menu appears (maybe the information is same).

Question: Why the Properties information look different for the same project type (class library) and same Target type in Visual Studio 2022?

Answer 1

The different dialogs are due to the project files being different kinds - there's the "old style" one (which is typically huge and lists every source file) and the "SDK-style" one (which is typically much smaller).

To create a new SDK-style project, target .NET Core or .NET 5+ in the wizard - you can always change the TargetFramework property to net472 or similar later.
