How would I add an output and an input value. Basically trying to take a disk size which is provided by an output and add to it an Input value. This isn't possible to do

Size = args.VmTemplate.Apply(x => x.Disks[0].Size ) + args.SrvExtendSize

as well as

Size = args.VmTemplate.Apply(x => x.Disks[0].Size ) + args.SrvExtendSize.ToOutput()

So I must be missing something

I think you can do something similar to this:

Output.Tuple<?, int>(args.VmTemplate, args.SrvExtendSize).Apply(t => {
   var (template, extendedSize) = t;
   return template.Disks[0].Size + args.SrvExtendSize;
});

that will take both inputs and make sure that both are counted in/awaited if needed before converting them into a single output.

Ah that seems to work.

Size = Output.Tuple(args.VmTemplate, args.SrvExtendSize).Apply(t => {
    var (template, extendedSize) = t;
    return template.Disks[0].Size + extendedSize;
}),

It just seems like a lot of work to just add two ints.

Welcome, been there before 😄
