I'm currently developing more and more sandboxed solutions for SharePoint Online. Upgrading them is an issue. You need to rename the WSP file and upload it that way because you can't just overwrite the WSP already in the solution store. After that, you can
upgrade via the interface (I suppose Powershell does it too) and you need to manually attach the debugger.
For upgrade scenario's, a "Upgrade (sandboxed)" deployment configuration would be awesome. It should take these steps:
- Rename the WSP, append a guid or package timestamp or something like that.
- Upload the renamed WSP to the sandbox solution store of the configured site
- Attach the visual studio debugger to the user code service
- Initialise the upgrade procedure
Any chance of such a thing being added in a new version of the development tools? Would be awesome!
