当前的.NET SDK不支持定位.NET Core 3.0.3.1 |5.0 [英] The current .NET SDK does not support targeting .NET Core 3.0 | 3.1 | 5.0

问题描述

我刚刚下载了.NET Core 3.0.100的发行版.
它与我安装的旧版本一起安装:

当我尝试针对.NET Core 3(< TargetFramework> netcoreapp3.0</TargetFramework> )的项目运行 dotnet restore 时，我得到了错误

 <代码> C:\ Program Files \ dotnet \ sdk \ 2.2.202 \ Sdks \ Microsoft.NET.Sdk \ targets \ Microsoft.NET.TargetFrameworkInference.targets(137,5):错误NETSDK1045:当前.NETSDK不支持定位.NET Core 3.0.目标.NET Core 2.2或更低版本，或者使用支持.NET Core 3.0的.NET SDK版本. 

我有一个global.json文件，该文件明确指出我需要 3.0.100 SDK

  {"sdk":{版本":"3.0.100"}} 

我知道我可以编辑 MSBuildSDKsPath env变量以指向 3.0.100 SDK，它可以工作，但我不想这样做，我的机器上还有其他项目，仍需要使用旧版本的.NET Core.

是否有一种方法可以使 dotnet 工具使用 global.json 中声明的SDK而不是 MSBuildSDKsPath 中的SDK?

我使用Visual Studio代码

解决方案

您还必须将 visual studio 更新到支持的最低版本:

.NET Core 3.0

• 最低 Visual Studio v16.3

.NET Core 3.1

• 最低 visual studio v16.5

.NET Core 5.0

• 最低 Visual Studio v16.6最新预览版

I've just downloaded the release version of .NET Core 3.0.100
It was installed alongside older version that I have:

When I try to run dotnet restore for a project that targets .NET Core 3 (<TargetFramework>netcoreapp3.0</TargetFramework>), I get this error

C:\Program Files\dotnet\sdk\2.2.202\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets(137,5): error NETSDK1045: The current .NET SDK does not support targeting .NET Core 3.0.  Either target .NET Core 2.2 or lower, or use a version of the .NET SDK that supports .NET Core 3.0.

I have a global.json file that explicitly states that I need the 3.0.100 SDK

{
  "sdk": {
    "version": "3.0.100"
  }
}

I know that I can edit the MSBuildSDKsPath env variable to point to the 3.0.100 SDK, and it works, but I don't want to do it, I have other projects on my machine that still need to use older versions of .NET Core.

Is there a way to make the dotnet tool use the SDK that's stated in global.json instead of the one in MSBuildSDKsPath?

Edit: I use Visual Studio Code

解决方案

You also have to update your visual studio to the minimum supported version:

.NET Core 3.0

• minimum visual studio v16.3

.NET Core 3.1

• minimum visual studio v16.5

.NET Core 5.0

• minimum visual studio v16.6 latest preview
