Piotr, I think you are fine referring to the full path above in GAC. It is a legit location.SSIS Tasks Components Scripts Services | http://www.cozyroc.com/

Topic is similar to http://social.msdn.microsoft.com/Forums/en-US/sqlintegrationservices/thread/e86260da-587d-4361-bee5-8976d683f77a. I have a problem with referencing assembilies Microsoft.SqlServer.DTSPipelineWrap, Microsoft.SqlServer.DTSRuntimeWrap, Microsoft.Sqlserver.ManagedDts, Microsoft.SqlServer.PipelineHost. My configuration: Windows XP with VS 2010 and BIDS 2008 (only VS 2008 shell, not a full version). I dont have these assemblies in C:\Program Files\Microsoft SQL Server\100\SDK\Assemblies. When I run GACUTIL, they are registered: C:\Program Files\Microsoft Visual Studio 10.0\VC>gacutil -l Microsoft.SqlServer. DTSPipelineWrap Microsoft (R) .NET Global Assembly Cache Utility. Version 4.0.30319.1 Copyright (c) Microsoft Corporation. All rights reserved. The Global Assembly Cache contains the following assemblies: Microsoft.SqlServer.DTSPipelineWrap, Version=10.0.0.0, Culture=neutral, Public KeyToken=89845dcd8080cc91, processorArchitecture=MSIL Number of items = 1 SSIS works fine on my PC. When I open SSIS component editor, I can see them on the reference list. Following path is displayed: C:\WINDOWS\assembly\GAC_MSIL\Microsoft.SqlServer.DTSPipelineWrap\10.0.0.0__89845dcd8080cc91\Microsoft.SqlServer.DTSPipelineWrap.dll The only way I found to add these assembles to VS 2010 project is to use this path. It just doesnt sound right to me, any thoughts?

Another option is to add following to the project file: <Reference Include="Microsoft.SqlServer.DTSPipelineWrap" /> <Reference Include="Microsoft.SQLServer.DTSRuntimeWrap" /> <Reference Include="Microsoft.SqlServer.PipelineHost" />
