This problem is very similiar to those: "The binary code for the script is not found" and The binary code for the script is not found” ssis
I have an SSIS project with multiple script files. SSIS claims that one of them has no binary even though there should be. There are no code errors, and I can build it properly. I suspect it's a VS bug because this problem appears and disappears randomly. What I mean by that is that this script is working fine, I open it to see the contents, close and suddenly this error happens! So I open it like 20 times, and it (without me doing anything) repairs itself! Any ideas on how to make it work better? It seems (though I can't confirm with 100% certainty) that this problem happens when you save the SSIS script (as in use ctrl+s) instead of simply exiting from the VS.
Things that I have tried that sometimes work:
Restarting Visual studio, opening the script without doing anything, closing it
Adding a small change to the code, exiting
Removing and adding breakpoints
Going on my knees in the direction of Redmond, Washington, and chanting the names of M$ presidents while opening and closing windows in the building to the rhythm of the windows starting sound
Randomly closing and opening the project, as well as going through items in the script component menu
Things that don't seem to work: rebuilding project, cleaning project, you know the standard stuff
I've found a solution that OFTEN works. Notice the usage of often.
1) Try restarting your computer.
2) If it doesn't work 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. DON'T SAVE THE SCRIPT PROJECT BEFORE CLOSING! JUST CLOSE!
Note that for the second step, you can also try using a cleaning tool, like CCleaner of similar.
