-**An important note on language support levels** - while many languages are supported, their level of support differs in important ways, making some languages more suitable than others for certain workloads. The **first class** languages are C#, F# and Javascript/Node.js. Functions written in these languages are run **in process** and are suitable for any workload. The remaining languages are considered **experimental**. Functions written in these languages are scripts that are run **out of process**. While there are many scenarios where this is acceptable, it won't be acceptable for high load scenarios where the overhead of a new process for each invocation won't scale. That said, there are many traditional WebJobs scenenarios where this limitation is acceptable.
