我必须怎么做才能修复我的项目的 "mismatch between processor architecture"?

What must I do to fix the "mismatch between processor architecture" of my projects?

我构建了一个 Winforms .NET Core 应用程序,我想将其提交到 Windows 商店。

根据该目标,我能够根据答案 创建应用程序包。

现在我想把我的应用程序放到 App Store 上。按照步骤 here,它告诉我,如果我“使用 Visual Studio 创建包”,我应该“将打包项目设置为启动项目,然后按 F5 启动您的应用程序。”

所以我这样做了,但收到了这条错误消息:

Error MSB3270 There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "C:\Users\bclay\source\repos\F4F_Core\F4F_Core\bin\Release\netcoreapp3.1\F4F_Core.dll", "x86". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project. WapProjTemplate1 C:\Program Files (x86)\Microsoft Visual Studio19\Community\MSBuild\Current\Bin\Microsoft.Common.CurrentVersion.targets 2123

因为我按照前面提到的答案(该答案的“更新”部分)中的具体说明进行操作,所以我现在不知道我应该更改什么,或者如何更改。

根据对上一个问题的回答,以下是我为 Winforms 应用程序选择的选项:

...对于 Windows 打包应用程序:

问题是您没有指定解决方案平台为X86,请在按F5之前将其编辑为x86。
