We have a custom assembly that works fine in SSRS 2008 R2.
We recently upgraded to SSRS 2012. Now the custom dll no longer works.
We are using this custom Dll in a report expression and it fails.
This Dll works fine when i use it Inside the BIDS and reports run fine under BIDS.
Is there some security change that were implemented on this report expression in SSRS 2012 , preventing our existing dll to stop working.
