.net core .NETCore 3.0未在VS2019中列为TargetFramework

我安装了NetCore 3.0 RTM SDK（x64），但无法在VisualStudio 2019（16.2.5）中将其作为目标

以下是我安装的运行时和SDK的版本：

C:\Users\pauls>dotnet --list-runtimes
Microsoft.AspNetCore.All 2.1.2 [c:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.1.9 [c:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.1.11 [c:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.1.12 [c:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.1.13 [c:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.2.6 [c:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.App 2.1.2 [c:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 2.1.9 [c:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 2.1.11 [c:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 2.1.12 [c:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 2.1.13 [c:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 2.2.6 [c:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 3.0.0 [c:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.NETCore.App 2.0.9 [c:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.1.9 [c:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.1.11 [c:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.1.12 [c:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.1.13 [c:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.2.6 [c:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 3.0.0 [c:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.WindowsDesktop.App 3.0.0 [c:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]

C:\Users\pauls>dotnet --list-sdks
2.1.202 [c:\Program Files\dotnet\sdk]
2.1.505 [c:\Program Files\dotnet\sdk]
2.1.700 [c:\Program Files\dotnet\sdk]
2.1.701 [c:\Program Files\dotnet\sdk]
2.1.801 [c:\Program Files\dotnet\sdk]
2.1.802 [c:\Program Files\dotnet\sdk]
2.2.301 [c:\Program Files\dotnet\sdk]
3.0.100 [c:\Program Files\dotnet\sdk]

这是我在VisualStudio中得到的。

我的路径变量包括

C:\Program Files\dotnet\

和

C:\Users\pauls\.dotnet\tools

。我也修复了安装并重新启动，但没有任何乐趣。目标框架选择不包括新项目和现有项目的核心3.0

有什么建议吗？

只有VisualStudio 2019 16.3.x支持Core 3.0

更新VS 2019并重试。

更新您的VS 2019并重试。

Doh！我通常依靠VS通知栏来告诉我何时有新的更新可用，但它没有显示任何内容。手动检查成功了，谢谢@RichardThank。我在这个问题上挣扎的时间比我想承认的要多。啊！我通常依靠VS通知栏来告诉我何时有新的更新可用，但它没有显示任何内容。手动检查成功了，谢谢@RichardThank。我在这个问题上挣扎了超过我愿意承认的时间。
