RazorLight 无法加载文件或程序集 System.Threading.AccessControl

Question

目标是从 .cshtml 文件生成 HTML

使用 RazorLight 时出现以下错误：

    System.IO.FileNotFoundException: Could not load file or assembly 'System.Threading.AccessControl, Version=4.0.5.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

我安装了 NuGet 包 RazorLight 2.0.0-rc.3 这是我从 .cshtml 文件生成 html 的代码：

private async Task<string> RenderRazorTemplate(string key, Type viewModelType, object viewModel)
{
  var engine = new RazorLightEngineBuilder()
    .UseEmbeddedResourcesProject(Assembly.GetExecutingAssembly()) // Use the Executing Assembly as project that embeds the .cshtml templates
    .SetOperatingAssembly(viewModelType.Assembly) // Without this, you'll get a Exception saying that the Assembly can't find the AntiForgery.dll
    .UseMemoryCachingProvider()
    .Build();
            
  return await engine.CompileRenderAsync(key, viewModel);
}

尝试添加 System.Threading.AccessControl NuGet 包，但无法加载另一个文件或程序集（因此添加包的故事永无止境）。一定有其他解决方案。

我正在使用.NET Core 3.1。

Answer 1

对我来说，问题是引擎被用在

IRequestHandler

的

Mediatr

中。

将引擎外包给控制器，而不是将其放在内部

IRequestHandler

解决了问题。

Answer 2

我只需通过 nuget 安装所有卸载程序集...它对我有用。
