SSIS 2012 SP1 "Value of null is not valid for stream" error on designer components

Question

I have just migrated a project from SSIS 2005 to SSIS 2012

Apart from the project, I had a custom pipeline component, which was also migrated to .NET 4.0, and installed in SQL Server DTS directory and the GAC, as usual.

After the migration, when I tried to open and configure the migrated component I got the error: "Value of null is not valid for stream".

The error only happened in "SSDT for BI" of VS 2012. When I tried to open and use the component in SQL Server Data Tools (VS 2010, not 2012, shell) it work without flaws.

So, this is a problem exclusive to SQL Server 2012 SP1 and SSDT for BI for VS2012

Answer 1

This problem affects SQL Server 2012 SSIS, and, in some occasssions, it doesn't even allow to open SSIS packages.

This error is solved with a Microsoft patch which can be downloaded from this page:

Particularly, to solve the problem in VS, as VS is a 32 bit application, you only have to install the x86 download.
