Visual Studio突然报错
Visual Studio suddenly bombing with errors
我正在使用 ASP.Net Core 5 和 EF Core 5 创建网站。
我突然删除了迁移文件夹中的所有迁移后 Visual Studio 开始用错误轰炸我，如下所示：
在顶部我收到这条消息：
在错误列表中我得到：
而且我无法再选择目标框架：
更新：
这是 .targets 文件的内容：

<!--
In VS 2010 SP1 and VS 2012, both supported for asset compatibility, the MSBuild installed
as part of them did not enforce using the local ToolsVersion (4.0) in all cases, but instead
just used whatever ToolsVersion was in the project file if it existed on the machine, and
only forced 4.0 if that ToolsVersion did not exist.
Moving forward, we do want to enforce a single acting ToolsVersion per version of Visual Studio,
but in order to approximate this behavior on VS 2010 SP1 and VS 2012 as well, we've redirected
the targets: If we're building using 4.X MSBuild (which doesn't define the new reserved
property, MSBuildAssemblyVersion), we'll point right back at the 4.0 targets, which still exist
as part of the .NET Framework. Only if we're using the new MSBuild will we point to the current
targets.
