Hi,
I was trying to get a define complex enablement expression like below with 2 facet requirements , but seemed only the first requirement was being recognized. It is entirely possible my enablement expression is not correctly formed.
What we actually want though is support for e.g. a Project PropertyTester and associated class in our enablement expression , so the class would get called with a handle to the project to glean information like what runtime is it targeting, does that runtime support our library (having some logic in the class to determine that.
So, can you tell me if the extension point supports more or less an arbitrarily complex enablement expression with property testers etc like we are looking for?
Thanks in advance for your help,
