Can't find external dll reference in SSIS 2012 script task

Hi,

I need to use an external dll (Newtonsoft.Json.dll) in my script task,

so i can parse the JSON strings efficiently.

I'm using VS2012 over SQL Server 2012 (SSIS) and the target framework of the internal script generated project is 4.0/4.5 (tried both)

i've read this article from microsoft-ssis.blogspot.be on referencing-custom-assembly-inside

, and using the gacutil.exe i've managed to add the dll to the .net 4 assembly location ...\windows\Microsoft.Net\assembly\GAC_MSIL.

inside the SSIS script i can't find the reference in the add reference dialog.

I even tried using older GAC to enter the dll to the ...\windows\assembly GAC but with no success as it says the assembly was created in a higher .Net version.

For my understanding i can't reference the file locally in the project because it will not work when deploying the package to the server

Any ideas?

Thanks!
