这里没有一个答案对我有用!!这里的大多数人都被困在Windows桌面应用程序控制台。如果你是一个使用ASP的web开发人员。NET在Visual Studio中看不到任何控制台或调试文本，下面是如何修复这个问题:

Paste the following two tests into your code so it runs both lines. These are tests for the output window: System.Console.WriteLine($"hello console!"); System.Diagnostics.Debug.WriteLine($"hello debugger!"); In Visual Studio choose VIEW > OUTPUT. You will see the results above in this output window after changing two settings below. When NOT DEBUGGING, in the OUTPUT window at the top under "Show Output From" choose: "YourProjectName - ASP.NET CORE Web Server". Run your code. You should see the "Console" text above. When DEBUGGING, in the OUTPUT window at the top under "Show Output From" choose: "Debugger". Run your code in debug mode. You should see the "Debug" text above.

或者你可以通过CTRL+F5进行调试，这将打开ConsoleWindow等待最后一行执行，直到你按下键。

在解决方案资源管理器中右键单击项目，然后单击“清洁”。

现在运行-按F5。

确保代码如下所示:

Console.WriteLine("TEST");
Console.ReadLine();

也许控制台正在清理。试一试:

Console.WriteLine("Test");
Console.ReadLine();

在你按回车键之前，它会一直在那里。

将执行模式改为“Self - Hosted”。在这种情况下，将出现执行控制台，并显示所有消息。
