How do I debug an ASPNET Core MVC Application Deployed in Azure

阅读更多关于 How do I debug an ASPNET Core MVC Application Deployed in Azure

问题 I've created a simple ASPNET Core 1.0 MVC app, which I am trying to deploy to Azure using Visual Studio. I am able to run this app locally on my machine using IIS Express, and navigate to my default route and display the page. However, in Azure I always get a 500 error every time, and at this point I am at a loss for how to get additional information. I've enabled detailed request logging in my Azure app, but it doesn't really seem to tell me much. ModuleName="AspNetCoreModule", Notification=

ASP.NET mvc View with IEnumerable model and input tag helper

阅读更多关于 ASP.NET mvc View with IEnumerable model and input tag helper

问题 In this official ASP.NET Core tutorial, I can use an Input Tag Helper as shown below. But due to a known model binding issue of form elements in a foreach loop, I want to use for loop instead. Question : If I were to replace @foreach (var item in Model) with @for (int i=0; i < Model.Count(); i++) in the following View . What would be my asp-for in <input asp-for="???" /> ? For some reason, intellisense is not recognizing, e.g, Model[i].BlogId or @Model[i].BlogId @model IEnumerable

阅读更多关于 Convention based binding in ASP.NET 5 / MVC 6

问题 It is possible to register dependencies manually: services.AddTransient<IEmailService, EmailService>(); services.AddTransient<ISmsService, SmsService>(); When there are too much dependencies, it becomes difficult to register all dependencies manually. What is the best way to implement a convention based binding in MVC 6 (beta 7)? P.S. In previous projects I used Ninject with ninject.extensions.conventions . But I can't find a Ninject adapter for MVC 6. 回答1: No, there is no support for batch

ASP.Net Core 2 ServiceProviderOptions.ValidateScopes Property

阅读更多关于 ASP.Net Core 2 ServiceProviderOptions.ValidateScopes Property

问题 What is ServiceProviderOptions.ValidateScopes exactly? I feel I couldn't understand completely what it does under the hood. I've come across this with a tutorial, but no explanation. 回答1: I assume you are speaking about this piece of code: services.BuildServiceProvider(new ServiceProviderOptions { ValidateScopes = true }); // or services.BuildServiceProvider(true); // or false ? The ASP.NET Core Provider has a mechanic which validates if a scoped service is resolved by a singleton container.

I wanna to check if the browser is IE and do something in razor page. I just made a function in razor page to do that.

问题 I added the line .UseUrls("http://*:5000") to enable clients from other hosts accessing the web api. public static void Main(string[] args) { var host = new WebHostBuilder() .UseKestrel() .UseContentRoot(Directory.GetCurrentDirectory()) .UseIISIntegration() .UseStartup<Startup>() .UseUrls("http://*:5000") // Added .Build(); host.Run(); } However, using browser to access localhost:5000/api/Test got the error of HTTP/1.1 400 Bad Request ?

Populating Dropdown in ASP.net Core

阅读更多关于 Populating Dropdown in ASP.net Core

问题 Does anyone know how to deal with Dropdowns in Asp.net core. I think I made myself very complicated to understand the new Asp.net core concept. (I am new to Asp.net Core). I have models called Driver , Vehicle . Basically one can create bunch of vehicles in the master then attach it to the Driver. So that the driver will be associated with a vehicle. My problem is that I am also using viewmodel in some area to combine two different models.(understood little from default template) My problem
