.net-core-2.1

问题 I want to use the HttpClientFactory that is available in .NET Core 2.1 but I also want to use the HttpClientHandler to utilize the AutomaticDecompression property when creating HttpClients .

Thanks, Jim 回答1: Actually I'm not using automatic decompression but the way to achieve this is to properly register http client services.AddHttpClient

问题 Is there any way to get a stack trace or inner exceptions on Swashbuckle/Swagger errors? At some point, it stopped working. I'm not sure if it was when I upgraded from .Net Core 2.0 to 2.1, but I'm pretty sure it was still working after that. When I navigate to myapidomain/swagger/index.html I get this error: Which is not very helpful. It was working 2 or so weeks ago... I didn't change any Swagger configuration. It's the same as it's always been: public void ConfigureServices

问题 My question is similar to this one (How to add copyright to published EXE (.Net Core)) which wasn't really answered. I have a .NET core executable project. I can put assembly information like AssemblyFileVersion into my .NET Core project and compile it, it will produce a DLL and Windows Explorer will show this info in the details tab of the file properties. When I publish as native x64 EXE, I'll get an EXE of the same name and the original DLL. But only the DLL will contain the assembly info

问题 In the latest .NET Core 2.1, an automatic validation for the model state validation is introduced (https://blogs.msdn.microsoft.com/webdev/2018/02/02/asp-net-core-2-1-roadmap/#mvc).

问题 We are using the code below to send the custom message from server side to client side in HTTP request. It is working properly in .NET Core 2.0 Response.HttpContext.Features.Get<IHttpResponseFeature>().ReasonPhrase While using the same code in .NET Core 2.1 it does not work. It doesn't throw any script errors but we couldn't get message in client side success. How to resolve this problem? 回答1: I hope it answers your question: This is not caused by any code changes in the framework, it's

问题 I want to use TextFieldParser in my project. For that I need using Microsoft.VisualBasic.FileIO . However Visual Studio accepts using Microsoft.VisualBasic without the FileIO . but it does not recognize the TextFieldParser class. On other forums, I read I should add Microsoft.VisualBasic reference.
