Breakpoint does not work within SSIS Script Component

Case
I cannot debug (use breakpoints) in a Script Component. What's wrong?

Solution
The Script Component does not support the use of breakpoints. Therefore, you cannot step through your code and examine values as the package runs. There are a few workarounds to still get some form of debugging.

1) MessageBox
The good old messagebox is a simple quick way of displaying some value. But it could be a little annoying with a lot of records.

// C# Code
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
    System.Windows.Forms.MessageBox.Show("SomeMessage: " + Row.YourColumn);
}

Messagebox.Show

2) Fire events
You can fire events and watch the execution result tab.

// C# Code
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
    bool fireAgain = true;
    this.ComponentMetaData.FireInformation(0, "ScriptComponent", "SomeMessage: " + Row.YourColumn, string.Empty, 0, ref fireAgain);
}

Partial Execution Results

3) Trace log
The .Net framework has it's own trace features which you can use the write messages to a listner. There are a lot of listners (third party, open source or your own custom handmade .net application), but your can also download one from Microsoft.com: DebugView for Windows.

// C# Code
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
    System.Diagnostics.Trace.WriteLine("SomeMessage: " + Row.YourColumn);
}

Let me know if you have an other workaround. And also see/vote for this Feedback request on Microsoft.com.
