One day, many years ago, I ran across THIS TOPIC announcing the Extensible Session Framework. I was intrigued, and my intrigue lead me to try it, and I liked it. The one big caveat was always the lifetime of the DVR. NI employees posted about a version 3.0 that was in the works and would solve this via an asynchronously launched daemon, if memory serves me right. But it's been radio silence for years now. I've DMed a few authors and not received any response (not sure they even work at NI anymore). Can anyone shed light on the status of ESF? I really found it useful in certain circumstances.
"Doc, why don't you just roll your own instead of look to NI to continue the ESF?", you say. Well, I have learned over the years that it is best in 99% of all circumstances to utilize frameworks that are popular, public, and widely adopted as opposed to making bespoke solutions. You and I are unlikely to be the last developers of our applications, it is far better if NI is the author or maintainer of a framework versus little 'ol me.
