.NET Core 3.0 在 VS2019 中未列为 TargetFramework

Question

我安装了 NetCore 3.0 RTM SDK (x64)，但无法在 VisualStudio 2019 (16.2.5) 中定位它。

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 Visual Studio 中得到的。

我的 PATH 变量包括 C:\Program Files\dotnet\ 和 C:\Users\pauls\.dotnet\tools。我还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。

更新您的 VS 2019 并重试。
