.net-core

问题 Unlike .NET Standard 1, .NET Standard 2 introduces a single netstandard.dll reference assembly. However, when compiling (with .NET Core SDK 2.2.203) with dotnet build we can see that it adds references to many assemblies (113), all under netstandard.library/2.0.3/build/netstandard2.0/ref/*.dll . One of these references is netstandard.dll . $ grep TargetFramework *.csproj <TargetFramework>netstandard2.0</TargetFramework> $ dotnet build --verbosity normal | grep -o netstandard.library/2.0.3

问题 I get why .Net Framework could cause issues in .Net Core, IE because an API specific to the Windows platform doesn't exist. But why wouldn't you be able to directly reference .Net Core as a library in .Net Framework? If .Net Core runs on windows, what is preventing a .Net Framework app from using .Net Core as if it were a library? I'm aware that you can port the .Net Core library to a .Net Standard Library, but my question is why .Net Framework can't just reference anything written in .Net

问题 I have json that looks like this, the key "123" could be any number. { "key1": "", "key2": { "items": { "123": { "pageid": 123, "name": "data" } } } } I want to deserialize or query the json with System.Text.Json so i can get the value of the key "name". How can I do that with System.Text.Json? I'm using .NET Core 3.1. 回答1: Something like: public class Rootobject { public string key1 { get; set; } public InnerObject key2 { get; set; } } public class InnerObject { public Dictionary<string,

问题 I am trying to describe a many-to-many self-referential relationship to Entity Framework Core 2. Essentially what I'm trying to model is a sort of tree structure, in which each element can have an arbitrary number of parent and child elements (so I guess more a graph than a tree). Here's what I have so far: public class OrgLevel { ... public ICollection<OrgLevelOrgLevels> OrgLevelOrgLevelsAsParent { get; set; } public ICollection<OrgLevelOrgLevels> OrgLevelOrgLevelsAsChild { get; set; }

问题 For integration testing Asp.Net Core application we have WebApplicationFactory. But how to test Worker ( HostedService ) that is not web application? I don't want to copy the whole DI configuration in SUT like in this question. Is it possible to use original configuration and override some of dependencies like we do for web application in WebApplicationFactory.WithWebHostBuilder? 回答1: I wasn't able to find any solution for Worker services integration testing hence I made adoption of

问题 I have the following situation. I have simplified the problem into the following example, although my real situation is more complicated. System.Text.Json does not serialise the object fully but Newtonsoft Json.NET does. Suppose I have the following class structure. public class A { public string AProperty { get; set; } = "A"; } public class A<T> : A where T : class, new() { public T TObject { get; set; } = new T(); } public class B { public string BProperty { get; set; } = "B"; } public

问题 I have a piece of code for setting up serilog based on some custom configuration combined with hosting environment. E.g. the application writes to one sink in development and another sink in production. I'm trying to figure out how to write tests for this piece of code. Basically, I want to write a test that checks that a sink only is added if the environment name is set to a given value, and that the sink configuration, like log file path, respects the custom configuration that I provide.
