I am creating a SSIS project via Biml (Using the current version of BimlExpress per the Varigence BimlExpress page) that uses a script component within a Data Flow Task. The project is created without issue however errors when it gets to the Script Component:
Could not load file or assembly 'Microsoft.SqlServer.DTSPipelineWrap, Version=14.100.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.
at ScriptMain.PreExecute() at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.PreExecute()
I can see this dll within the GAC and when I try to add the reference manually, SSIS states that I can't add it as it is already included in the project.
However, if I open the Script Component and manually Build it - but change nothing else - the Data Flow Task will run through without issue.
To clarify, I know I have changed nothing else as I am recreating this project from the Biml each time I want to test a new approach, which provides a consistent baseline.
Does anyone know why a Script Component that includes a reference to a GAC dll, will only work when manually Built but not beforehand?
I have used this exact Biml before without issue, though on a different environment. Worked using Visual Studio 2012 against a SQL Server 2016 instance yet doesn't here within Visual Studio 2015 (targeting 2012) against a SQL Server 2016 instance.
For further context I have also tested this outputting the SSIS Project targeted at SQL Server 2012, 2014 and 2016 with the exact same error message.
Update
This appears to definitely be a dll version problem in the project as output from BimlExpress, in that if I manually create the v4.0_14.100.0.0__89845dcd8080cc91 folder with the version 13 dll inside at C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.SqlServer.DTSPipelineWrap the script component now errors out with the following:
System.InvalidCastException: Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSComponentMetaData100'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{ID removed just in case}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
