阅读更多关于 .Net Core 2.2 Web API 405

问题 I am trying to setup a .net core 2.2 web api to use a post verb. Anything other than a get verb returns a 405 no matter if it is run on my local machine (w10 iis eXPRESS 10.0) or the windows server (2016 R2 IIS 8.0). I've read the other posts about disabling WebDav in your config file, adding a route, and completely removing the WebDav feature. I have done all of those to no avail. I'm just starting to develop in core and find this baffling, on the same server is a non-core web api that runs

To clear up some confusion, the contents of the dictionary will be the response from a call to a webservice. ConcurrentDictionary<string, Response> _cache = new ConcurrentDictionary<string, Response>(); var

问题 How do I create framework-dependent executables (FDE) with .NET Core 2.2? The MSDN documentation mentions them here as a new feature for .NET Core 2.2: Framework-dependent executables (FDE) Starting with .NET Core 2.2, you can deploy your app as an FDE, along with any required third-party dependencies.
