The development of SharePoint Workflows is not so complicated as you might think.
But you need the right tools:
Visual Studio 2008 and VSTO Power tool: SharePoint Workflow package generator combined enables you to debug realtime on your development server and everytime you build your workflow the SharePoint Workflow package generator creates a wsp file that you can install on the productionserver…fantastic!
The combination between the powertool and VS2008 is not out of the box, you need to add a few XML code lines to your csproj/vbproj file to get a wsp file after every build.
What do you need:
Visual studio 2008
Start Visual Studio on your development server for debug purposes. Create your workflow and hit F5!
If you want to create a wsp (solution) file every time you build at the following code at the end of your csproj/vbproj file,
First of all instal the Powertools from the site above.
Secondly enter these lines of code
Finally hit Ctrl+b
Now you see that there is an [solutionname].wsp in your project directory.
