问题描述

我构建并部署了一个 .Net Core 控制台应用程序.

I had a .Net Core console app built and deployed.

项目的平台目标是 x86.

The project's Platform target is x86.

目标框架是 .Net Core 2.2(x86).

Target framework is .Net Core 2.2(x86).

虽然安装了 .Net Core 2.2 (x86) SDK，但在开发人员命令提示符 VS2017 中执行命令 dotnet myapp.dll 后，我收到以下错误.

Although .Net Core 2.2 (x86) SDK is installed, I get following error after executing the command dotnet myapp.dll in Developer Command Prompt VS2017.

It was not possible to find any compatible framework version
The specified framework 'Microsoft.NETCore.App', version '2.2.0' was not found.
- The following versions are installed:
2.0.7 at [C:Program FilesdotnetsharedMicrosoft.NETCore.App]
2.0.9 at [C:Program FilesdotnetsharedMicrosoft.NETCore.App]
2.1.5 at [C:Program FilesdotnetsharedMicrosoft.NETCore.App]

.Net Core 2.2(x86) SDK 安装在C:Program Files (x86)dotnetshared"路径下，系统环境变量包含C:Program Files (x86)dotnet".

The .Net Core 2.2(x86) SDK was installed under path "C:Program Files (x86)dotnetshared", and System Environment Variables contains "C:Program Files (x86)dotnet".

有什么建议吗?谢谢！

推荐答案

这似乎是 .Net Core 安装的一个已知问题，github.com/dotnet/core-setup/issues/4350

It seem to be a known issue for .Net Core installation, github.com/dotnet/core-setup/issues/4350

我必须卸载所有 .Net Core 包，包括 x64 和 x86，然后重新安装 .Net Core x86 包.这解决了问题.

I have to uninstall all .Net Core packages, both x64 and x86, then reinstalled .Net Core x86 package. And that solved the problem.
