How to change a script task version in SSIS? I added a script task to an SSIS project in VS2015. When I deployed to SQL Server 2016 I got an error message that the version 15.0 script is not supported. 

Where does this version 15 come from? Reading other, similar questions on Stack Overflow I see that you can set the target version of the project to SQL Server 2012 - which I did (the eventual deployment target is SQL Server 2012).

I also tried deleting and recreating the script task. And in the information of the script it says it's using V10 of C#.

How can I resolve this?


  Script Task:Error: There was an exception while loading Script Task from XML: System.Exception: The Script Task ""ST_a1ad9dc5972c42b68c12a13155f10b6d"" uses version 15.0 script that is not supported in this release of Integration Services. To run the package, use the Script Task to create a new VSTA script. In most cases, scripts are converted automatically to use a supported version, when you open a SQL Server Integration Services package in %SQL_PRODUCT_SHORT_NAME% Integration Services.

I have also opened the project in SSDT 2012 and rebuilt with a different name. Same error. It seems that there must be a reference that wasn't deleted or something.

None of the solutions on this question (https://stackoverflow.com/questions/34893267/ssis-script-task-vs15-not-work-when-deploy-on-sql-server-2014) worked.

Looking at the XML in the package where the script is, I can easily find that task, and there is no reference to version 15 anywhere.

=========== EDIT

After copying the project to the machine that hosts the database, opening VS2015 and deploying from there, the package executes.

And then when going back to my machine and building there, it doesn't.

Is this a bug? Or am I doing something stupid by expecting the build to produce the same deployment wizard as using the wizard from VS...

I have SQL Server 2016 (13.0.4411.0), ssisdb has the schema version (13.0.1601.5). 

I am using an integration services package created in visual studio 2015. The script component has the path: C:\Program Files (x86)\Microsoft SQL Server\130\DTS\Binn\VSTA14_IS_ST_CS_Template.vstax It won't let me execute the package through the integration services catalog (due to the message experienced by Zach). However it appears that it will let me execute it through the file system (using SQL Agent). Unsure if this is working, will update this once the package has completed.
I believe I have the same issue, and here is the work around that got over my issue. 

Details first: 


I have sql server 2016 (13.0.4411.0)
SSISDB has the schema version (13.0.1601.5)
I am using an integration services package created in visual studio
The script component (Which states it is 2015 C#) has the path:
C:\Program Files (x86)\Microsoft SQL
Server\130\DTS\Binn\VSTA14_IS_ST_CS_Template.vstax


If I deploy to the catalog through SSMS, it won't let me execute the package through the integration services catalog (due to the message experienced by Zach - version 15.0 not supported).

The workaround: 

If I deploy the package through Visual Studio to the 'Integration Services Catalog' on the required instance, this message goes away and the project runs successfully. This is not ideal as we should be able to deploy through SSMS, but meant that the project can progress.
