Configuration variables are created on a specific configuration and they can only be accessed by builds that belong to that configuration. Configuration variables are read-only at run time and they Configuration Variables can be created, modified and deleted through the Configuration Wizard.
Configuration variables are server variables and can only be updated during the build by the Set Variable action set to update server variables or the Persist Build Variable build event handler. A write lock is required to update server variables during the build. The initial value of a configuration variable at the start of the build is copied to an agent variable and can be accessed with the the %Configuration.MyVariableName% syntax.Configuration Variables can be created, modified and deleted through the Configuration Wizard syntax. Agent variables can only be updated using the options to synchronise agent variables in the Set Variable and Load Variable actions.
Project Variables
Project variables are created on a specific project and they can only be accessed by configurations and builds that belong to that project. Project variables are read-only at run time and they Variables can be created, modified and deleted through the Project Wizard.

Agent variables can only be updated using the options to synchronise agent variables in the Set Variable and Load Variable actions.
Application Variables
Application variables are system wide variables that every build, configuration and project can access. This means that any variable defined variable defined in the application namespace can be used anywhere in Continua CI. These These are the highest variables that the user can define. Application Variables can be created, modified and deleted through the Variables page in the administration section.

Environment Variables
