Earlier releases of PDK for .NET

Hello,

Where can I find earlier releases of PDK for .NET, as the one

available in [here|https://www.sdn.sap.com/irj/sdn/dotnet?rid=/webcontent/uuid/3ecbe347-0a01-0010-5897-dc8f159ae3de#section2 [original link is broken]] is for EP 7.0, and it produces exception when I try to

run deployed PAR under our portal which is currently 6 Package 21. Below is the exception:

Portal Runtime Error

An exception occurred while processing your request

Exception id: 05:06_22/03/08_0017_208365350

See the details for the exception ID in the log file.

Thanks,

Ali.
