.net-core-3.1

问题 Goal: I am confused by the behavior I am seeing with exceptions in my .Net Core library. The goal of this question is to understand why it is doing what I am seeing. Executive Summary I thought that when an async method is called, the code in it is executed synchronously until it hits the first await. If that is the case, then, if an exception is thrown during that "synchronous code", why is it not propagated up to the calling method? (As a normal synchronous method would do.) Example Code:

问题 For .NET Core 3.1, console application how can I read a complex object from appsetting.json file and cast it into the corresponding object?

问题 I made a WPF and Console application for someone to use on their private server which I can't have access to. I used Visual Studio 2019's built-in "Publishing Wizard" to create Framework Dependant single-file apps. When the person opened the WPF app they were greeted with the standard warning: They clicked yes and to my understanding, they installed .Net Core 3.1 which is what the applications target. After they restarted the computer they got the exact same warning again. I wasn't sure what
