所有需要Net6.0的Nuget软件包与Net6.0不兼容。即使完成Windows重置
启动PC后，我尝试继续使用以前从事的项目： ASP.NET MVC Core 6.0。
突然之间，Microsoft.EntityFrameWorkCore未安装在解决方案中。 尝试重新安装Microsoft.entityFrameworkCore Nuget软件包后，我收到了以下错误：
Package restore failed. Rolling back package changes for 'BulkyBook' (my project)
NU1202: Package Microsoft.Extensions.Logging 6.0.0 is not compatible with net6.0 (.NETCoreApp,Version=v6.0). Package Microsoft.Extensions.Logging 6.0.0 does not support any target frameworks.
NU1202: Package Microsoft.Extensions.Options 6.0.0 is not compatible with net6.0 (.NETCoreApp,Version=v6.0). Package Microsoft.Extensions.Options 6.0.0 does not support any target frameworks.
...对于所有依赖关系以及
NU1202: Package Microsoft.EntityFrameworkCore 6.0.5 is not compatible with net6.0 (.NETCoreApp,Version=v6.0). Package Microsoft.EntityFrameworkCore 6.0.0 does not support any target frameworks.
尝试安装任何需要Net6.0的Nuget软件包时，我会遇到相同的问题。
我已经重置了Windows（保留文件，但失去所有程序），并且完全重新安装了Visual Studio 2022.我仍然存在相同的问题。
这杀死了我，我愿意尝试任何事情。 证明图像：
After booting up my PC I tried to continue using a previous project I had been working on:
ASP.NET MVC Core 6.0.
All of a sudden Microsoft.EntityFrameworkCore was not installed in the solution.
After trying to reinstall the Microsoft.EntityFrameworkCore nuget package I received the following errors:
Package restore failed. Rolling back package changes for 'BulkyBook' (my project)
NU1202: Package Microsoft.Extensions.Logging 6.0.0 is not compatible with net6.0 (.NETCoreApp,Version=v6.0). Package Microsoft.Extensions.Logging 6.0.0 does not support any target frameworks.
NU1202: Package Microsoft.Extensions.Options 6.0.0 is not compatible with net6.0 (.NETCoreApp,Version=v6.0). Package Microsoft.Extensions.Options 6.0.0 does not support any target frameworks.
... for all dependencies AND
NU1202: Package Microsoft.EntityFrameworkCore 6.0.5 is not compatible with net6.0 (.NETCoreApp,Version=v6.0). Package Microsoft.EntityFrameworkCore 6.0.0 does not support any target frameworks.
When trying to install ANY nuget packages requiring net6.0 I get the same issue.
I have done a reset of Windows (keeping files but losing all programs) and fully reinstalled Visual Studio 2022.I still have the same issue.
This is killing me, I'm willing to try anything.

您的项目文件很可能指定＆lt; targetFramework＆gt; net6.0＆lt;/targetFramework＆gt;。将其更改为＆lt; targetFramework＆gt; net6.0-windows＆lt;/targetFramework＆gt;然后重试。
您也可能会感兴趣的是，如果＆lt; usewindowsforms＆gt; true＆lt;/usewindowsforms＆gt;已指定并LT; outputType＆gt;不存在，您有一个具有Winforms依赖性的类库。
Quite possibly, your Project file specifies <TargetFramework>net6.0</TargetFramework>. Change this to <TargetFramework>net6.0-windows</TargetFramework> and try again.
It might also interest you to know that if <UseWindowsForms>true</UseWindowsForms> has been specified and <OutputType> is absent, you have a class Library with WinForms dependencies.
