DataFlows.NET is a replacement for SQL Server Integration Services (SSIS) designed to have a fluent programming model with proper intellisense, testability and extensibility. Much of what SSIS does is already built into .NET but leveraging the SSIS features often requires much more code that isn't easy to read.
The goal of this library is to design code that is easy to read, easy to maintain and easy to test.
The library was built with a full suite of tests first to guide the overall design. You must have a local SQL Server instance running for the tests to work though.
