Within this little blog-post you can find the SharePoint Workflow Project Templates that I have used in my Demo Extravaganzza session on Tuesday - they are also available within the ECM Starter Kit as an installer-package. As I have used these templates with a build very close to the final release I expect those templates to work with the final release as well. To install the templates, please follow the following steps:

• Unzip the ZIP Archive I have attached to this blog post.
• Open a Command Prompt and execute install.bat.
• The Install.bat script actually sets up the project templates for Visual Studio 2005, but it does not import the snippets nor does it add the controls to the tool-box. So you have to do that manually.
• To add the Activities to the toolbox, just create a new Tab in Visual Studio's toolbox and call it "SharePoint Workflow". Then right-click the toolbox and select Choose Items. All all Activities that you can find within the Microsoft.sharepoint.WorkflowActions assembly (you can use the "add items" dialog-box to filter based on the Microsoft.SharePoint.Workflow namespace name).
• Next you can import the code snippets using the Visual Studio 2005 Code Snippet Manager (CTRL+K, CTRL+B), which are by default copied to the "%ProgramFiles%\Microsoft Visual Studio 8\Xml\1033\Snippets\SharePoint Workflow" directory. I'd recommend adding the whole folder in the code-snippets manager - then you are going to get exactly the same experience as I got in my session.

If you want to have a more convenient way of installing the templates, they are part of a sample project which has been published on MSDN. Finally these templates are part of the Enterprise Content Management Starter Kit which has been released for Beta 2 of Office SharePoint Server.
