I created something similar in .NET recently for SSIS 2008 as part of a Masters project. It basically encapsulated and simplified the access to the SSIS object model allowing packages to be quickly built in C# using simple declarations and methods.

Creating a For Each Loop container:

ForEachLoopContainer ForEachFile = new ForEachLoopContainer(SQ,

"For Each File",

"C:\\Data",

"IncomingData.csv",

"FileName");

Inserting a SQL Task into the container:

SQLTask LogFile = new SQLTask(ForEachFile,

"Log File",

OleDBConnectionString,

"insert into Filelog

(InputFileName, DateProcessed)

values(?, getdate())");

I thought that the advantage of this over the BIML model was that it meant developers already fluent in SSIS and C# didn't have to learn another language.
