.net-standard

问题 From the last (or maybe the two last) update, I can't update the package NETStandartLibrary in Nuget. I just create a new standard library project. See this message : In project's properties, the version is different : And in the .csproj : <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <TargetFramework>netstandard1.4</TargetFramework> </PropertyGroup> </Project> In Nuget, I add the dependency 'Microsoft.EntityFrameworkCore', then I got the warning : Warning Detected package downgrade:

问题 My current specific situation is that I want to use DataContractSerializer Class in a library supporting .NETStandard1.3. I am unable to reference it in the library.

问题 I've got a cross platform (iOS and Android) Xamarin solution using .NET Standard 2.0. The solution is being built by Visual Studio 2017 (I've tried both the current and preview versions). The Forms and Android projects build fine. However, the iOS fails to build, with the following error: 1>CSC : error CS1703: Multiple assemblies with equivalent identity have been imported: 'C:\Users\newuser.nuget\packages\system.reflection.emit\4.3.0\ref\netstandard1.1\System.Reflection.Emit.dll' and 'C:

问题 There is a framework-level navigation element at Microsoft Docs called ".NET Platform Extensions". It contains docs on recently added APIs like System.IO.Pipelines and System.Threading.Channels for example, as well as a whole bunch of other APIs, including the not-so-recent ones. Some APIs from this collection are available as nuget packages (for both .Net Core and .Net Framework), but others are not seemingly available. Also, as of now, there is no nuget package called ".NET Platform

问题 At the moment I'm porting an asp web api to .Net Core. The api uses a Class library which provides some implementations of the ActionFilterAttribute class. So I have to port this class library as well. When I tried to add the nuget package Microsoft.AspNetCore.All to the class library I recived this error: Package Microsoft.AspNetCore.All 2.0.0 is not compatible with netstandard2.0 When I change the target framework to netcoreapp2.0, I'm able to install the package, but of course I need an

问题 I want to integrate NMVS protocol in my application which is providing wsdl files for testing which is written sample code in .net framework library. I want to test it in .netstandard, .netcore or UWP app but wsdl files only support to "WSHttpBinding" which is not supported in .netstandard, .net core and UWP. <wsdl:binding name="WSHttpBinding_ISinglePackServices" type="ns:ISinglePackServices"> WSHttpBinding binding = new WSHttpBinding(); binding.Security.Mode = SecurityMode.Transport; binding

问题 I have an console application (in dot net core 1.1) which is scheduled in cron scheduler for every 1 min. Inside the application there is call to configuration file. I'm attaching the code below. public static T GetAppConfig<T>(string key, T defaultValue = default(T)) { T value = default(T); logger.Debug($"Reading App Config {key}"); try { var environmentName = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT"); var builder = new ConfigurationBuilder() .AddJsonFile($"appsettings

问题 I am a contributor to a GitHub project, and recently we had some trouble with our .NET Standard 2.0 project installing correctly into a .NET Framework 4.5 project. The cause of this is that (if I am understanding correctly) .NET Standard 2.0 supports a minimum .NET Framework of 4.6.1. OK, fair enough. So we updated the .csproj to create another framework output: <TargetFrameworks>netstandard2.0;net45</TargetFrameworks> In our testing project, the supported frameworks are defined as such:
