问题 I'm trying to check if a property has an attribute. This used to be done with: Attribute.IsDefined(propertyInfo, typeof(AttributeClass)); However I get a warning that it's not available in DNX Core 5.0 (it still is in DNX 4.5.1). Has it not been implemented yet or has it moved like other type/reflection related stuff? I'm using beta7. 回答1: Edit: There actually seems to be an IsDefined extension method in the System.Reflection.Extensions package. Usage: var defined = propertyInfo.IsDefined

问题 I am getting a 500 Internal Server Error when deploying our ASP.NET 5 web application to an Azure Web App. How do I get the details and stacktrace for this exception? I have done the following but with no luck: Using the diagnostics error page on startup: app.UseErrorPage(); Setting ASPNET_ENV in Azure portal: Using DNX beta 6. 回答1: In case this helps someone, I've found out that if you're using ASP.NET RC1 and you're using Azure WebApps and add an App setting called Hosting:Environment with

问题 I'm working with the namespaces System.Runtime.Remoting.Proxies and System.Runtime.Remoting.Messaging for AOP in C#. I'm trying to port my application from .Net Framework 4.6 to dnxcore/dotnet core. Intellisense says, that these two namespaces are not available with my framework-vesion (netcoreapp1.0 / dnxcore50). Any idea if these two namespaces will appear? or any idea how to get the AOP like with the RealProxy -class? I don't want to use 3rd-party-libraries - I only want to use what .Net

问题 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

问题 Today I installed VS 2015 on Windows 7 x64. Mainly to test new .Net Core features and etc. And for test I created new C# "Console Application (Package)" solution and got this message: DNX SDK version 'dnx-clr-win-x86.1.0.0-beta5' failed to install. The solution will use DNX SDK version ‘dnx-clr-win-x86.1.0.0-beta5’ for this session. I can't compile and debug project. Also, when I have opened debug tab in project properties then VS crashed. DNVM output when I opened solution: Invoke-Command :

问题 I used to be able to inject runtime services like IApplicationEnvironment into the constructor of the Pogram class of a DNX console application. However, using the latest CI build of RC1, the services no longer get injected: public Program(IApplicationEnvironment env) { if (env == null) { // env is null. throw new ArgumentNullException(nameof(env)); } } 回答1: The DNX platform wants to be compatible with regular Program.Main entry points. Therefore they removed dependency injection into the

问题 When restoring packages in the new xproj project types, there are the new package config in the project.json : "dependencies": { "Microsoft.AspNet.Authentication.Cookies": "1.0.0-rc1-final", "Microsoft.AspNet.Authentication.Facebook": "1.0.0-rc1-final", "Microsoft.AspNet.Authentication.Google": "1.0.0-rc1-final", .... } Nuget restores theese with no problem. When the .xproj depends on normal .proj files, you sometimes needs to create wrappers, and write the dependency like this: "frameworks":
