Thanks You can inject IHttpContextAccessor implementation to your view and use it to get the Session object @using Microsoft.AspNetCore.Http @inject IHttpContextAccessor

In my project I want to log all the errors happen in the application in a database table. I catch almost all errors using try catch blocks, but I cannot catch the global errors like 4xx and 5xx. There are cases that the application does not redirect to the Exception Handler defined in the Configure method of the Startup.cs like when I type a url which does not exist. app.UseExceptionHandler("/Error"); Is there a way to catch all the unhandled errors occurred in my application? You could create your own Exception filter, which implements IExceptionFilter e.g.: public class GlobalExceptionFilter

I am having a simple middleware which fetches the body of the request and store it in a string. It is reading fine the stream, but the issue is it wont call my controller which called just after I read the stream and throw the error A non-empty request body is required . Below is my code. public async Task Invoke(HttpContext httpContext) { var timer = Stopwatch.StartNew(); ReadBodyFromHttpContext(httpContext); await _next(httpContext); timer.Stop(); } private string ReadBodyFromHttpContext(HttpContext httpContext) { return await new StreamReader(httpContext.Request.Body).ReadToEndAsync(); }

How do I define default value for property in swagger generated from following API? public class SearchQuery { public string OrderBy { get; set; } [DefaultValue(OrderDirection.Descending)] public OrderDirection OrderDirection { get; set; } = OrderDirection.Descending; } public IActionResult SearchPendingCases(SearchQuery queryInput); Swashbuckle generates OrderDirection as required parameter. I would like to be it optional and indicate to client the default value (not sure if swagger supports this). I don't like making the property type nullable. Is there any other option? Ideally using built

I'm writing a simple ASP.NET Core service using ASP.NET Core empty ( web ) template. By default, it binds to port 5000 but I would like it to bind to a random available port on the system. I can do so by modifying BuildWebHost to: public static IWebHost BuildWebHost(string[] args) => WebHost.CreateDefaultBuilder(args) .UseStartup<Startup>() .UseUrls("http://*:0") // This enables binding to random port .Build(); It binds to a random port but how do I determine from within the application which port I'm listening to? Hosting addresses of ASP.NET Core application could be accessed via

I am trying to enable application logs in azure. I have a dummy Net Core 2 App running in an appService in azure. and basically my goal is to see the trace messages in the log stream and in the application log files but I have not found the right way to do this. One of the challenge I have found reading other posts is that they assume a web config in place. The documentation for ASP.NET Core 2.2 is here . Firstly, enable Application Logging and choose the appropriate level: This may be all you need to do to diagnose any problems. But if you want log messages and see them, install the Microsoft

I'm trying to use in my ASP.NET Core 2.0 web app this sample RazorViewEngineEmailTemplates to create an html email body from View. But when I run it and my controller gets an ajax request, I get this error: Cannot resolve scoped service Microsoft.AspNetCore.Mvc.ViewFeatures.Internal.IViewBufferScope from root provider It's probably coming from resolving dependencies in the RazorViewToStringRenderer class but I have no idea how to fix this. ok, the problem was I used renderer from a Singleton service (EmailerService). I changed its registration to Scoped and it all works now: services.AddScoped

I just migrated an ASP.Net Core 1.1 application to the new 2.0 version that was just released. Now I get the following exception: System.BadImageFormatException: 'Could not load file or assembly 'dotnet-aspnet-codegenerator-design' or one of its dependencies. An attempt was made to load a program with an incorrect format.'
