I am trying to deploy a report to the server with a custom assembly for the first time. I am able to deploy the same report without the assembly. I am using Reporting Servic
It turned out I needed to copy the dll to this folder on the report server:
%ProgramFiles%\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportServer\bin
That is the only place it is needed on the report server if you just want to deploy reports to it.
