VB.NET
vMix Scripting supports the majority of VB.NET 2.0 code that will work within a single sub or function.
This means that custom classes and structures are not supported, however you can use the vast majority of
the built in base classes in the .NET framework
including the handy System.Net.WebClient for downloading data over the internet.
