在另一个程序集中找到 Razor Pages

Question

我想在另一个程序集中找到“我的项目 Razor 页面”。为此，我编写以下代码：

public void ConfigureServices(IServiceCollection services)
{
    var adminAssembly = Assembly.Load(new AssemblyName("App"));
    services.AddMvc().AddApplicationPart(adminAssembly).AddRazorOptions(options =>
    {
        var previous = options.CompilationCallback;
        options.CompilationCallback = context =>
        {
            previous?.Invoke(context);

            context.Compilation = context.Compilation.AddReferences(
                MetadataReference.CreateFromFile(typeof(dodo).Assembly.Location));
        };
    });

    services.Configure<RazorViewEngineOptions>(options =>
    {
        options.FileProviders.Add(new EmbeddedFileProvider(Assembly.Load("App")));
        options.FileProviders.Add(new PhysicalFileProvider(@"C:\Users\soheil\Documents\Visual Studio 2017\Projects\WebApplication5\App"));
    });
}

我的解决方案：

运行时localhost:5000/SameTodo出现以下错误：

缺少一个或多个编译参考。确保您的项目引用“Microsoft.NET.Sdk.Web”并且“PreserveCompilationContext”属性未设置为 false。

堆：

找不到类型或命名空间名称“SameTodoModel”（您是否缺少 using 指令或程序集引用？） + public global::Microsoft.AspNetCore.Mvc.Rendering.IHtmlHelper Html { get; 私人套装；无法找到类型或命名空间名称“SameTodoModel”（是否缺少 using 指令或程序集引用？） + public global::Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary ViewData => (global::Microsoft.AspNetCore .Mvc.ViewFeatures.ViewDataDictionary)PageContext?.ViewData; 找不到类型或命名空间名称“SameTodoModel”（您是否缺少 using 指令或程序集引用？） + public SameTodoModel Model => ViewData.Model; 找不到类型或命名空间名称“SameTodoModel”（是否缺少 using 指令或程序集引用？） + public global::Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary ViewData => (global::Microsoft.AspNetCore. Mvc.ViewFeatures.ViewDataDictionary)PageContext?.ViewData;

并设置PreserveCompilationContext为 false 但现在有效我该如何解决这个问题？

public void ConfigureServices(IServiceCollection services)
{
    var adminAssembly = Assembly.Load(new AssemblyName("App"));
    services.AddMvc().AddApplicationPart(adminAssembly).AddRazorOptions(options =>
    {
        var previous = options.CompilationCallback;
        options.CompilationCallback = context =>
        {
            previous?.Invoke(context);

            var referenceAssemblies = AppDomain.CurrentDomain.GetAssemblies()
                .Where(x => !x.IsDynamic&& !string.IsNullOrEmpty(x.Location))
                .Select(x => MetadataReference.CreateFromFile(x.Location))
                .ToList();

            //add dynamic
            var dynamicAssembly = typeof(DynamicAttribute).Assembly;
                 referenceAssemblies.Add(MetadataReference.CreateFromFile(dynamicAssembly.Location));

            context.Compilation = context.Compilation.AddReferences(referenceAssemblies);
        };
    });

    services.Configure<RazorViewEngineOptions>(options =>
    {
        options.FileProviders.Add(new EmbeddedFileProvider(Assembly.Load("App")));
        options.FileProviders.Add(new PhysicalFileProvider(@"C:\Users\soheil\Documents\Visual Studio 2017\Projects\WebApplication5\App"));
    });
}
