A question about `Input&lt;T&gt;` and `Output&lt;T&gt;` as they pertain to a C# program.
If resource A takes an `Input&lt;string&gt;` and I want to construct that string using a pattern including one or more `Output&lt;string&gt;` from resource B, how should I do that?
I assume the following is too naïve:
```resourceA.SomeInput = $"{resourceB.FirstOutput}...{resourceB.SecondOutput}";```
Is there some string formatter implementation of `Output&lt;T&gt;` perhaps?

Hm, I think maybe I found something by looking around in Object Browser a bit.

Looks like I could do:
```resourceA.SomeInput = Output.Format($"{resourceB.FirstOutput}...{resourceB.SecondOutput}");```
Because the string interpolation will be cast automatically by the compiler to a `System.FormattableString` .
Very elegant! :thumbsup:

That’s right. See this section of the docs for more details: <https://www.pulumi.com/docs/intro/concepts/programming-model/#outputs-and-strings|https://www.pulumi.com/docs/intro/concepts/programming-model/#outputs-and-strings>
