推荐答案

我在尝试安装 .Net Core 2.0 后遇到了这个错误，似乎把它搞砸了.对于 dotnet restore、dotnet build 或 dotnet msbuild，我会得到同样的错误.本质上，任何涉及 .Net Core 和 msbuild 的内容.

I encountered this error after playing around with .Net Core 2.0 installation and seemingly messing it up. I would get this same error for dotnet restore, dotnet build or dotnet msbuild. Essentially, anything involving .Net Core and msbuild.

发生错误是因为 MSBuildSDKsPath 环境变量仍然指向旧的 .Net Core 1.1 SDK.

The error occurred because the MSBuildSDKsPath environment variable was still pointing to the old .Net Core 1.1 SDK.

为了解决这个问题，我手动将 MSBuildSDKsPath 环境变量设置为指向 2.0.0 的 SDK 路径，对于 x64 的我来说，这是在:C:Program Filesdotnetsdk2.0.0Sdks.

To fix the problem, I manually set the MSBuildSDKsPath environment variable to point to 2.0.0's SDK path, which, for me with x64, this was at: C:Program Filesdotnetsdk2.0.0Sdks.

基本上，如果您的 .csproj 中有 Sdk="Microsoft.NET.Sdk"，那么您的 中应该存在一个同名的文件夹MSBuildSDKsPath 位置.

Basically, if you have Sdk="Microsoft.NET.Sdk" in your .csproj, then a folder with the same name should exist at your MSBuildSDKsPath location.
