Alternative solution to HostingEnvironment.QueueBackgroundWorkItem in .NET Core

阅读更多关于 Alternative solution to HostingEnvironment.QueueBackgroundWorkItem in .NET Core

问题 We are working with .NET Core Web Api, and looking for a lightweight solution to log requests with variable intensity into database, but don't want client's to wait for the saving process. Unfortunately there's no HostingEnvironment.QueueBackgroundWorkItem(..) implemented in dnx , and Task.Run(..) is not safe. Is there any elegant solution? 回答1: QueueBackgroundWorkItem is gone, but we've got IApplicationLifetime instead of IRegisteredObject , which is being used by the former one. And it

Can't compile Environment.Exit in .NET Core

阅读更多关于 Can't compile Environment.Exit in .NET Core

Related: System.Environment in .NET Core I'm trying to compile a program which uses Environment.Exit in .NET Core. I've used yo aspnet to create the default console application, installed System.Runtime.Extensions and then added a call to Environment.Exit(1) (full sample on github ). When running dnu build I get this error: C:\git\environmentexit\ConsoleApplication\Program.cs(13,25): DNXCore,Version=v5.0 error CS0117: 'Environment' does not contain a definition for 'Exit' As far as I can tell, this corefx pull request should mean that Environment.Exit is exposed, so I can't figure out what

HttpClient in ASP.NET 5.0 not found?

阅读更多关于 HttpClient in ASP.NET 5.0 not found?

Using VS2015 and asp.net 5, when I try to compile my site using an instance of System.Net.HttpClient, it tells me: The type or namespace name 'HttpClient' could not be found (are you missing a using directive or an assembly reference?) Hovering over the offending code, I see: "WebApplication1.ASP.NET 5.0 - Available" "WebApplication1.ASP.NET Core 5.0 - Not Available" I have 2 frameworks listed in my project.json file: "frameworks": { "aspnet50": { }, "aspnetcore50": { } }, I'm assuming that one of these is responsible by not having the assembly, but I don't really know how to fix it or how

How to reference Windows.winmd from a .NET Core library?

阅读更多关于 How to reference Windows.winmd from a .NET Core library?

问题 I'm looking to use Windows Runtime types, like Frame or Button , from a .NET Core library. It seemed to be working fine when I was using a traditional PCL, targeted for Windows/Windows Phone 8.1. For some reason, however, it's not compiling after I switched my project to DNX. Here's my project.json : { "frameworks": { // Profile32 == Windows + Windows Phone 8.1 ".NETPortable,Version=v4.6,Profile=Profile32": { } } } And here is my sample code: using System.Linq; using Windows.UI.Xaml.Controls;

How can I diagnose missing dependencies (or other loader failures) in dnx?

I'm trying to run a modified version of the HelloWeb sample for ASP.NET vNext on DNX using Kestrel. I understand that this is very much on the bleeding edge, but I would hope that the ASP.NET team would at least keep the simplest possible web app working :) Environment: Linux (Ubuntu, pretty much) Mono 3.12.1 DNX 1.0.0-beta4-11257 (I have 11249 available too) "Web app" code, in Startup.cs : using Microsoft.AspNet.Builder; public class Startup { public void Configure(IApplicationBuilder app) { app.UseWelcomePage(); } } Project config, in project.json : { "dependencies": { "Kestrel": "1.0.0

Self-Registering Libraries with Autofac 4 and vNext

阅读更多关于 Self-Registering Libraries with Autofac 4 and vNext

问题 i'd like to create a Plugin Enviroment for my ASP.Net 5.0 / MVC 6 Application. I'm using Autofac as IOC Container and i like to load the Plugins (Class Libraries) from the build in DNX LibraryManager. The goal of using the Library Manager is, that i don't have to care about NuGet Packages and Frameworks. The Problem i have is the LifeCycle, i have to build the IOC Container before the instance of the LibraryManager is available. Because the Autofac Container provides his own IServiceProvider

Is it possible to run ASP.NET 5 site directly on Kestrel in Azure WebApps?

阅读更多关于 Is it possible to run ASP.NET 5 site directly on Kestrel in Azure WebApps?

问题 I have checked that in the web response the server is IIS when I deploy ASP.NET5 to azure web app, so I guess the IIS platform handler is used to redirect it to Kestrel. So I am wondering if it is possible to run directly on Kestrel, and what benefits/drawbacks will that have (probably regardless if it's in Azure or not). I suppose it will be a bit faster since IIS will be excluded from the pipline, but it should not be too much overhead I suppose... 回答1: On Azure Web App, you cannot bypass

Is .NET Execution Environment (DNX) similar to mono?

阅读更多关于 Is .NET Execution Environment (DNX) similar to mono?

Here is the description of DNX: The .NET Execution Environment (DNX) is a software development kit (SDK) and runtime environment that has everything you need to build and run .NET applications for Windows, Mac and Linux. It provide a host process, CLR hosting logic and managed entry point discovery. DNX was built for running cross-platform ASP.NET Web applications, but it can run other types of .NET applications, too, such as cross-platform console apps. Is DNX alternative of mono? If not, then what will be the difference? Is DNX alternative of mono? If not, then what will be the difference?

阅读更多关于 Building a .NET Core app via command line, so that it works on a machine without .NET Core installed

问题 My end goal is to create a cross-platform (non-web) console application, so I'm exploring .NET Core right now. In my previous .NET projects, I did all the development inside Visual Studio, but I also created a batch/MSBuild file so I could build the whole project (including setups, NuGet packages, zip files with binaries etc.) with one single click. Here's an example from a previous project. In the end, I want to do something similar with my .NET Core test project. But right now I'm failing
