SSIS issues with the script task

Question

I am working on some packages. I got some error message: the binary code for the script is not found. please open the script in the designer by clicking......

And I searched online, some information says I just need to delete the existing script task and create a new one. And copy the code to the new task, but I did it, still have some errors. (I am using the visual studio 2012). Anyone please help me find something that caused the issue. By the way, this script task worked find before. Don't know when the issue started. Thank you so much!!

Here is the scripts:

Hi @Ilovemygarden ,

You may try below methods to see if it will be helpful.

1.In the VstaProject Window choose Build -> Build ST_xxx to see if there is any error there.

2.Go to your system temp files directory, and find the location of SSIS temp projects (you can also open the script, right click on C# project, explore in windows explorer). Delete the project. (Make copies before deleting just in case). Start Visual studio, and once again edit script, close, hope it works.

3.Copy the package to other machine which has same environment (SSDT 2012) and check if it works on other computer.

If it works, it means that the issue is related to the tool itself on your machine, you could uninstall the SSDT and reinstall them.

Please also check the Target version of SQL Server and corresponding development environment for SSIS packages:

2016-->>SSDT for VS 2015

2014-->>SSDT for VS 2015 or SSDT for VS 2013

2012-->>SSDT for VS 2015 or SSDT for VS 2012

2008-->>BIDS 2008

Someone mentioned that script task works in VS2015 but have the some issue in VS2012 you may have a try.

Answer 2

@ZoeHui-MSFT
It seems that I need to update the ClosedXML, but I couldn't update in VS. I searched online, and some information says that I need update Nuget package first. But I couldn't do that either. because download is not allowed before it is approved. But we do have different version of ClosedXML in our shared folder. But don't know how to install it to my VS. Any thoughts about this? Thank you!!

Answer 3

Hi @Ilovemygarden ,

Do you mean that you have the ClosedXML.nupkg in shared folder?

If yes, you may have a try with below steps.

In VS--Tools--Opinions--Package Sources--Add new source with local path or shared path.

And then use Manage nuget packages to install the new source.
