Question

我正在尝试将网络框架中的一些旧代码移植到网络核心。我已经在Windows 10中成功做到了（它可以完全编译并运行）。我现在正在尝试使其在MacOS Mojave中运行，因为我有一台Mac，并且不想使用虚拟机。

代码可以正确编译，但是当它尝试运行时，系统会说找不到合适的网络核心版本。

我已经尝试过重新安装以前安装了netcore的Visual Studio。

我还尝试过“ hello world”示例，它可以编译并完美运行。

它显示的错误是：

It was not possible to find any compatible framework version
The specified framework 'Microsoft.WindowsDesktop.App', version '3.0.0-preview5-27626-15' was not found.
  - No frameworks were found.

You can resolve the problem by installing the specified framework and/or SDK.

The .NET Core frameworks can be found at:

我不知道问题可能出在哪里；我希望程序能够运行，因为已经安装了正确的运行时。

您似乎正尝试使用Mac OS不支持的Windows Forms / WPF框架。

找不到NetCore 3.0.0 Framework版本，即使它已安装在MacOS中
