Question

Dot NET CORE 我试图在MVC CORE web API灵魂中添加MVC视图PAGE。我添加了控制器和视图，但是一旦我尝试访问它，它就会产生如下运行时错误。

如果我选择Web应用程序创建项目，一切正常。但是我有一个现有的rest API项目，这使我创建了两个项目。我认为我们可以扩展相同的项目来托管Rest API以及网页（如果需要）。我们不能吗？

Startup.cs

     public void Configure(IApplicationBuilder app, ILoggerFactory loggerFactory)
        {
            loggerFactory.AddConsole(LogLevel.Debug);
            app.UseDeveloperExceptionPage();
            app.UseCors(options => options.AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod());
            app.UseStaticFiles();
            app.UseOAuthValidation();
            app.UseOpenIddict();
            app.UseMvcWithDefaultRoute();
            app.UseStaticFiles();

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }

 public void ConfigureServices(IServiceCollection services)
        {
            services.AddCors();
            services.AddMvc();
            services.AddAutoMapper();
            services.AddDbContext<ApplicationDbContext>(options =>

            services.AddIdentity<ApplicationUser, IdentityRole<Guid>>()
                .AddEntityFrameworkStores<ApplicationDbContext, Guid>()
                .AddDefaultTokenProviders();
            services.AddOpenIddict<ApplicationUser, IdentityRole<Guid>, ApplicationDbContext, Guid>()

                .AllowAuthorizationCodeFlow()
                .AllowPasswordFlow()
                .AllowRefreshTokenFlow()
                .DisableHttpsRequirement()

                .AddEphemeralSigningKey();
            services.AddTransient<IEmailSender, AuthMessageSender>();
        }

似乎我们需要在project.json中将preserveCompilationContext设置为true。这是运行时编译Razor视图所必需的。

  "buildOptions": {
        "emitEntryPoint": true,
        "debugType": "portable",
        "preserveCompilationContext": true
      },
