Setting VSTS Release Variable Values At the Time of Creating a Release

VSTS builds have the option to set build variable values at the time of queuing a build. You have to select option for build variable “Settable at queue time” to enable the variable to be set its value at the time of queuing  build. However, this feature was not available for VSTS Release and there was a user voice raised here requesting to allow setting release variables at the time of creating a release. As promised by MSFT, this feature is now available for VSTS Release. Let’s look at how to use it with VSTS web UI and with the VSTS REST API.
