Blazor wasm failed to start platform. Reason: TypeError: NetworkError when attempting to fetch resource

Question

我正在尝试发布我的 blazor wasm 项目。当我点击托管它的 url 时，应用程序永远不会加载，并且我在控制台中看到此错误：

Error: Failed to start platform. Reason: TypeError: NetworkError when attempting to fetch resource.

这个错误并没有真正让我继续下去......任何人都知道我什至可以从哪里开始寻找以试图弄清楚发生了什么？

我想通了 - 事实证明，当我安装 .NET 6 时，发布开始到 trim 程序集（即使我使用 VS2019 发布）。我不得不通过将其添加到我的 blazor csproj 来禁用它：

   <PropertyGroup>
      <PublishTrimmed>false</PublishTrimmed>
   </PropertyGroup>
