问题 The NLog documentation explains how to configure NLog for .NET Core applications by using an nlog.config XML file. However, I'd prefer to have just one configuration file for my application - appsettings.json . For .NET Framework apps, it's possible to put the NLog configuration in app.config or web.config . Is it possible to put the NLog config in appsettings.json in the same way? For example, how could I put this configuration example from the NLog documentation for ASP.NET Core 2 into

问题 I am running an inherited project written in C# inside Visual Studio Code. In order for this application to run, it needs to take command line input (-t, -h, etc). How do I test this from inside Visual Studio? Currently (I've been learning dotnet, C#, VS, etc as I go) I have a hello world program I can run from vsc's terminal. For a reason I haven't been able to pinpoint, probably how I installed it, dotnet run isn't recognized - I have to feed it an explicit path to dotnet.exe: C:\Program

问题 I have an ASP.NET Core web app, with WebAPI controllers. All I am trying to do is, in some of the controllers, be able to kick off a process that would run in the background, but the controller should go ahead and return before that process is done. I don't want the consumers of the service to have to wait for this job to finish. I have seen all of the posts about IHostedService and BackgroundService, but none of them seem to be what I want. Also, all these examples show you how to set things

问题 I have been following Logging in ASP.NET Core Which is working just fine. I have a question about this line _logger.LogWarning(LoggingEvents.GetItemNotFound, "GetById({ID}) NOT FOUND", id); I am wondering why they are not using $ - string interpolation? _logger.LogWarning(LoggingEvents.GetItemNotFound, $"GetById({ID}) NOT FOUND"); Why would the LogWarning extension have a params object[] args paramater? Whats the point when you can just send everything in string message. I assume there is a

问题 What's the best option to use in a Web API that will return both HTTP status codes and JSON results? I've always used IActionResult but it was always a Web App with a Web API. This time it's only Web API .
