当前.Net SDK不支持目标.Net Core 2.2目标.Net Core 2.1或更低版本 [英] The Current .Net SDK does not support targeting .Net Core 2.2 Target .Net Core 2.1 or Lower

问题描述

我在.net core 2.2预览版3的预览版中有一些项目。
在我将VS Studio社区版更新为15.9.2版之前，它运行良好。
之后，将无法再定位.net core 2.2预览。
当我执行 dotnet --list-sdks 时，会获得安装的SDK列表，包括2.2.100-preview3。

I have some projects in the preview version of .net core 2.2 preview 3. It was working fine until i updated my VS Studio Community Edition to Version 15.9.2. After that targeting .net core 2.2 preview is no longer possible. When i do dotnet --list-sdks I get a list of the SDKs installed including 2.2.100-preview3.

更新VS Studio之后，列表现在仅显示

After updating VS Studio, the list now only shows

我遵循了类似的问题，但无法解决该问题。
是否有任何指针？

I have followed similar questions but could not resolve the issue. Any pointers?

似乎最新版本关闭了预览功能，
使用.NET Core SDK的预览功能菜单->工具->选项->项目和解决方案-> .NET Core

seems that the latest release turns off the use of preview, "Use previews of the .NET Core SDK" option under menu -> Tools -> Options -> Projects and Solutions -> .NET Core

转到此处将其重新打开。

go here to turn it back on.
