t is illegal to call out while inside message filter. (Exception from HRESULT: 0x80010005 (RPC_E_CANTCALLOUT_INEXTERNALCALL)) (Microsoft Visual Studio)

Is this an error thrown by BIDS while you were working on an SSIS package? Will need steps to reproduce please + some basic technical info as versions, etc.Arthur

I have also been seeing this error, randomly, since I upgraded my client tools to SQL Server (including BIDS) to SQL Server 2008 R2, but only in one very large package that contains several web references to MS CRM 4.0 web services. Cumulative hotfixes have not helped. It occurs perhaps one in ten times in BIDS when I edit a data flow script component (source, transformation, or destination, doesn't matter), edit the script, close the VSTA window, and then click OK on the script component dialog. After clicking OK apparently the script component is "built" and it is during (or just before or after) that build that the exception is thrown. If I do a build while using VSTA, I do not see this error. It only occurs when completing the script component editing dialog.

Oh yes, this occurs using BIDS to edit SSIS packages. Here is a link to an MSDN blog from 5 years ago describing a possible cause but offering no solution: http://blogs.msdn.com/b/ashvinis/archive/2005/09/27/474560.aspx My workaround is to copy my C# code to the clipboard before exiting VSTA, so that I can at least put it back when the exception occurs. Any changes I make in the script component editor dialog are lost and must be redone.

One other note -- the size of the script component being edited doesn't seem to matter. I have one source component and two destination components containing web references to CRM, and two small transformation components containing no web references. The exception can occur when I complete editing of any of these script components, but I don't see it under any other circumstances.

I started getting this error again. After reading,"If I do a build while using VSTA, I do not see this error" - I tried that - and it worked. While in the script edit window, after coding, before saving and closing window, click build, then close window. The error didn't appear. Thanks!
