Perhaps this question has been answered before.
I am looking to upgrade a custom SSIS component that was based on .NET framework 2 and works with SQL Server 2008 R2 to SQLServer 2012.
The problem I am facing is : The component shows up in the Toolbox items in the SQLServer 2008 R2 Business Intelligence Studio,but it does not show up in the SSIS toolbox for SQL Server 2012 Datatools. The components have been copied over to the appropriate SQLServer\110\DTS\PipelineComponents folder and has been added to the Gac.
Based on this link, it should just show up : http://msdn.microsoft.com/en-us/library/ff929137.aspx
