解决方案

您没有提到您的项目的类型.但总的来说，您应该遵循官方文档.例如，对于 winforms 项目，请参阅 How to将 Windows 窗体桌面应用迁移到 .NET 5.

很可能，首先，您需要手动编辑您的项目文件并将其更改为 SDK 样式，如以上文章所述:

<属性组>...</PropertyGroup></项目>

Recently Microsoft has release .NET 5. If we want to upgrade .NET Framework 4.8 to .net 5 then how can we accomplish this task.

Please Note :

1. I had already upgrade Visual Studio 18.2 with all latest component and .net Framework 5. But in project property .net 5 is not displayed.

2. My application is in .net Framework not in .net core.

解决方案

You didn't mention what's the type of your project. But in general, you should follow the official docs. For example, for winforms projects, see How to migrate a Windows Forms desktop app to .NET 5.

Most likely, as the first thing, you will need to edit your project file manually and change it to the SDK style, as described in the article above:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
   ...
  </PropertyGroup>

</Project>
