How to debug Silverlight 3 C# Application?

How to debug Silverlight 3 C# Application? Using VS or Blend... or some tool\开发者_开发问答plugin?

I think we can debug SL 4 application if it is opened through IE! I had already spent 1 hour finding out "why debugging is not working". Somehow tried in IE and it worked perfectly :)

Normally this works just by attaching to the Firefox / Browser of choice process.

--Edit In Visual Studio you'd choose the Debug menu option then Attach To Process, then select Firefox.exe or IExplore.exe.

Here's a discussion on the Silverlight Forums of using VS 2008 to debug Silverlight - the bonus is they describe the steps while troubleshooting. You can try the same for Silverlight 3; although the discussion centers around a different version, steps are likely similar.
