The PPM product team is considering rewriting the PPM MS Project plugin. The current code is in MS Visual Basic and needs updating. We are planning to use .Net however this would require users to have the .Net framework installed or install it when they want to use the PPM MSP plugin. Would this be an issue for your organization?
Generally, it's something we can and do install - but it's not currently installed on every system. So, making sure everyone who needed it had the correct version installed would require some lead time.
It would typically only be an issue for us as a company if the version required conflicted with what other applications required.
