Excel-DNA - CSharpAddIn Sample
==============================

This sample creates a compiled library that will be loaded as an Excel add-in using the Excel-DNA runtime.

Debugging
---------
Easiest debugging is to put the full path to Excel.exe (e.g. C:\Program Files\Microsoft Office\Office14\Excel.exe) into 
   Project Properties -> Debugging tab, Start external program:.
In the Command line arguments: box, enter the full path to SampleCS.xll, 
or jsut File->Open the SampleCS.xll when Excel is running.
Then start debugging with F5.

You can also attach the debugger to a running instance of the Excel process.
Do the following:
1. Build the project.
2. Start Excel externally.
3. Load the SampleCS.xll using File->Open.
4. In Visual Studio select Debug->Attach to Process,
   select Excel.exe
   select the debugger type (Attach to:...) to be "Managed (v4.0) code only"

To make changes in the code without restarting Excel:
1. Detach the debugger (Debug->Detach All).
2. Make changes and rebuild.
3. Reload the add-in in Excel (File->Open ... SamplesCS.xll).
4. Attach debugger again.
