|Azure Functions 3.0 Goes Live|

Azure Functions 3.0 has been released with the ability to target .NET Core 3.1 and Node 12, though it won't become the default for new apps until Microsoft has made some tooling improvements to the new release.
Azure Functions is a service that you can use to set up functions that are activated when specific events happen, such as an HTTP request, an event from a queue, timer or SQL trigger - any event from another service can trigger a function. It fulfills a similar role to AWS Lambda on the Amazon cloud.
The only breaking change for .NET is that synchronous server operations are disabled by default.
However, while the new release is production ready, it won't be the default version for developers until January 2020. In a blog post, Microsoft said:
"While the runtime is now ready for production, and most of the tooling and performance optimizations are rolling out soon, there are still some tooling improvements to come before we announce Functions 3.0 as the default for new apps."
Microsoft isn't going to deprecate earlier versions of Azure Functions, and customers running Azure Functions targeting 1.0 or 2.0 will also continue to receive security updates and patches moving forward—to both the Azure Functions runtime and the underlying .NET runtime—for apps running in Azure.
