Deployment to several databases using SQL Server Data Tools and TFS using a Custom Workflow file

Continuous integration with SQL Server Data Tools and Team Foundation Server

I have been mostly writing about the interaction between SQL Server Data Tools and Team Foundation Server. Microsoft provides a hosted version of Team Foundation Build Service called Visual Studio Online. The configuration and functionality is mostly the same than what I have previously been writing about but there are some specifics things that we need to be aware when using Visual Studio Online Build Service.

In the previous blog post : Deployment to several databases using SQL Server Data Tools and Team foundation Server I illustrated how it is possible to use TFS and a batch file to deploy a database to several SQL Server instances or to deploy several SQL Server databases to several instances. The main way to achieve that in the previous post was using a batch file. For more information about this technique please have a look at that blog post.

In this post on the other hand I will demonstrate how the same functionality can be achieved using a Windows Workflow Foundation file (xaml) deployment file and Team Foundation Server.

In the previous post : Continuous Integration with SSDT and TFS I have described some techniques to allow continuous integration / deployment using SQL Server Data Tools and Team Foundation Server. The solution described works great for deploying to a single instance of a database.
