Uno 平台：Wasm 的 Debug.Writeline 没有 output 任何东西

Question

I'm trying to figure out how to debug Uno Platform apps for the Wasm target. Breakpoints don't work and I have not figured out how to get debug output to work, either.

For example, I have in App.xaml.cs

public App()
{
  ...
  Debug.WriteLine("OnStart.begin");
}

and

using System.Diagnostics;

But noting appears in the "output" window when I run the app. Is there a different logging technique I should use?

EDIT

I followed the instructions, mentioned by Jerome, and opened the debug panel for my app. However, there were no further instructions displayed at that point and I didn't see any scripts that seemed to resemble my app. See attached screenshot. What should I be looking for?

Answer 1

Debug.WriteLine is not supported on WebAssembly at this point.

You can use Console.WriteLine() instead, or use the logging facilities provided by the default Uno app template (using this.Log().Debug(...) , and the [ConfigureLoggers][1] method)
