Reporting services - custom library is not working after installing report on production Server

I created a report which uses custom libra开发者_C百科ry created by me. I've copied these libraries to the following folders:

c:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer\bin\

c:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies\

Everything works fine when I run the report using on development environment using Visual Studio. When I install it on Production Server (where these dlls were also copied) the following error is returned:

Failed to load expression host assembly. Details: The type initializer for 'MyParserForReportingServices.MyParser' threw an exception. (rsErrorLoadingExprHostAssembly) Can someone please help me?

add your dll to this folder too

C:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportManager\Bin

I had the same issue, and copied the DLL to the ReportServer folder and worked!!

Weird because in the doc. the ReportManager is mentioned but ReportServer not.

Thanks Masoud!
