The files that appear in the solution explorer automatically when you create a new Sequential Workflow Library are:

· Feature xml (DeploymentFiles\FeatureFiles) :
o This xml file is used to put together a workflow as a feature, in order for it to be deployed into SharePoint. When creating the project, this file is almost blank.
· Workflow.xml (DeploymentFiles\FeatureFiles) :
o This workflow xml file is the final piece the developer needs to deploy workflow to SharePoint. At the beginning, this file is almost blank too.
· Manifest.xml (DeploymentFiles\ProductionDeployment) :
o This is used in the process of packaging the workflow into a solution file.
· wsp_Structure.ddf (DeploymentFiles\ProductionDeployment) :
o Only used for the production deployment.
· PostBuildActions.bat (DeploymentFiles) :
o The batch file needed for the deployment of the workflow produced.
· Workflow1.cs :
o This is the file needed by the developer, to construct his/her workflow. This file comes by the name Workflow1.cs by default, but the developer is encouraged to change its name into a significant one.
