I'm debugging a UWP in C#. On a certain moment the console stops giving me the write line content.
Does anyone can imagen what the problem could be?

Console.WriteLine or Debug.Writeline are inappropriate for tracing or logging. Use a proper logging library – Panagiotis Kanavos Jan 26 '18 at 12:53

BTW Debug.WriteLine won't work in Release builds. – Panagiotis Kanavos Jan 26 '18 at 12:54

3`Console.WriteLine()` works fine, but for some project it does not. With `WPF + .Net Framework` it works, with `WPF + .Net Core 3` it does not. – Nicke Manarin Sep 17 '20 at 15:34

The Console.WriteLine isn't for IDE output window. It writes to console. So, you could use Debug.WriteLine() which is available in System.Diagnostics

Also remember that you need DEBUG flag to use this. see [HERE](https://stackoverflow.com/questions/1159755/where-does-system-diagnostics-debug-write-output-appear) – Krzysztof Skowronek Jan 26 '18 at 12:55

Oh man, I totally forgot which one to use. Why doesn't Console.WriteLine throw an error when there's no console? – Matt Gregory Jun 11 '20 at 20:36

Console.WriteLine or Debug.Writeline are inappropriate for tracing or logging. The real solution is to use a logging library.
The Output Window of the debugger is not the console. If you want to write to it use Debug.WriteLine. You can do this because the Output Window is registered as a listener for .NET's tracing infrastructure.
This won't work in Release mode though. You'd need to use Trace.WriteLine for this but you'd also need to register your own listeners. You'd also need to specify message levels to separate errors from verbose messages and eg write only erros to log files.
At this point though, it's just as easy to add and configure a logging library like Serilog or NLog that have providers for rolling files, databases, logging servers etc.

If you wanna see some messages in "Output" you should use Debug.WriteLine. For this add using System.Diagnostics.
If you use WindowsForm, for example, you can't just use Console.WriteLine.
