.net-standard

问题 I am working on couple of projects one of which is an ASP.NET 4.5 application and other one is .Net Core API 1.1 project. The asp.net application is using HttpContext classes to read cookies and page headers. Now, I need to move this to a .net standard library which can be used by both the project. I don't find HttpContext in .net standard SDK. Any suggestions? 回答1: There's a problem to your approach: .NET Standard is the most bare-bones implementation of .NET available, meaning that only

问题 We have been trying to run EF Core Migration in .Net Standard 1.6 class library, but it has been failing. But same passes very well in .Net Core 1.1 class library. Is EF Migration supported in .NET STANDARD? 回答1: The documentation covers this case as know issue/limitation when the DbContext is placed inside an netstandardx.y Class Library. Workaround 1 - Use an app as the startup project If you have an existing .NET Core App or .NET Framework App (including an ASP.NET Core Web Application),

问题 I understand targeting .NET Standard 2 means that the frameworks between .net core, mono and the full .net framework, but I'd like to understand what that means for the binaries created by the different frameworks. So if I create a console program targeting .NET Standard 2 and compile using .NET Framework, can only the full .NET Framework run this file? If they can all run the files, how would I run the .NET Core .dll executable console using the full framework or Mono? So basically are the

问题 I'm writing an MVC website using ASP.NET Core 2.0. In the ASP.NET Core project (let's call it Web ), I reference a .NET Standard 2 project in the same solution (let's call it Service ). The Service project also references a third .NET Standard 2 library in the solution (let's call this one Business ). The Business project declares a type called Model . The problem is that I can use Model in the Web project (i.e. the compiler sees the type Model and I can do var a = new Model(); ) as if the

问题 With the new .csproj format (as well as the old), it is possible to add files as linked outside of the project folder: <EmbeddedResource Include="..\..\..\Demo\Sample.cs" Link="Resources\Sample.cs" /> It is also possible to use a glob pattern to include multiple files: <EmbeddedResource Include="..\..\..\Demo\*.cs" /> But how do you combine the two? What I Tried <EmbeddedResource Include="..\..\..\Demo\*.cs" Link="Resources\*.cs" /> <EmbeddedResource Include="..\..\..\Demo\*.cs" Link=

问题 I have a .Net Standard library, and I'm getting an error when trying to use one of the dependant libraries, which I believe is down to a version conflict. In an old style .Net Class library, I might add something like this: <?xml version="1.0" encoding="utf-8"?> <configuration> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" /> <bindingRedirect oldVersion="0.0

问题 I've some problem when using .net standard in .net framework 4.6.2 consoleapps. I could reduce the problem to this: Given: I create a .net standard 1.5 client library vis vs 2017 with this single class public class Class1 { public List<int> Get() { return new List<int>() { 1, 2, 3, 4, 5, 65, 6 }; } } Now I create a new .net 4.6.2 console application which is just calling the method of this class: static void Main(string[] args) { var foo = new Class1(); Console.WriteLine("Done!"); Console

问题 In Visual Studio, there are at least 3 different types of class library you can create: Class Library (.NET Framework) Class Library (.NET Standard) Class Library (.NET Core) While the first is what we've been using for years, a major point of confusion I've been having is when to use the .NET Standard and .NET Core class library types. I've been bitten by this recently when attempting to multi-target different framework versions, and creating a unit test project. So, what is the difference

问题 In Visual Studio 2019 Advanced Build settings, C# 8 does not appear to be available for a .NET Framework project, only (as in the picture below) for a .NET Core 3.0 project: Does C# 8 support the .NET Framework? 回答1: Yes, C# 8 can be used with the .NET Framework and other targets older than .NET Core 3.0/.NET Standard 2.1 in Visual Studio 2019 (or older versions of Visual Studio if you install a Nuget package). The language version must be set to 8.0 in the csproj file. Most - but not all -
