问题 I have an MVC 6 site that has been deployed as an Azure Web App. I have enabled all tracing / diagnostic options in Visual Studio using Server Explorer. I am trying to do remote debugging, but I am only seeing an Error 500 on my browser, and not finding any information (or triggering an error breakpoint) on where exactly the error occurred. I can't find any error trace on the file logs that I get from Azure. How should I troubleshoot Error 500's in an Azure Web App? Adding "CustomErrors": {

问题 Is it possible to invoke a View Component from controller and render it to a string? I am really looking for some code example for this.

问题 Well, lets get down to it. I'm using Visual Studio 2015 and ASP.NET core tag helpers have completely stopped working, no idea why as I've not changed anything. I was in work one day, they worked fine, then I came in the next day and now no ASP.NET core web project at all shows any tag helpers!?! I've tried creating a fresh new ASP.NET core mvc project and they don't work there either!!! I'm completely stuck, is there some setting somewhere that completely turns them off in Visual Studio? Note

问题 Is it possible for an ASP.NET 5-beta4 console application (built from the ASP.NET Console project template in VS2015) to use the Startup class to handle registering services and setting up configuration details? I've tried to create a typical Startup class, but it never seems to be called when running the console application via dnx . run or inside Visual Studio 2015. Startup.cs is pretty much: public class Startup { public Startup(IHostingEnvironment env) { Configuration configuration = new

问题 I’m using MVC 6 and would like to be able to access a particular namespace globally from all of my Razor views.

问题 I followed the Safe storage of app secrets during development guide over on the asp.net docs during development but it does not describe how to use it when publishing to another machine for QA, Production, etc. What I figured it would do was insert them into the appsettings.json during publish but it does not. I ended up having to place my SendGrid keys and other sensitive information directly into the appsettings.json which really defeats the purpose of the app secrets. Is using app secrets

问题 Here's the skeleton of a standard ASP.NET Core application: var config = new ConfigurationBuilder() .AddCommandLine(args) .AddEnvironmentVariables(prefix: "ASPNETCORE_") .Build(); var host = new WebHostBuilder() .UseConfiguration(config) .UseKestrel() .UseContentRoot(Directory.GetCurrentDirectory()) .UseIISIntegration() .UseStartup<Startup>() .Build(); host.Run(); In this piece the ASP.NET Core apparatus instantiates an instance of Startup.cs class .UseStartup<Startup>() My query is how can I

问题 I am running an ASP.NET 5 project in an Azure Web App. When calling on an API endpoint with a file (form-data) of about 1.5mb or larger, the following exception is thrown.
