In Unity 2017 it's now possible to use interpolated strings in Unity if you change the .NET version that Unity uses. Interpolated strings is a feature from C# 6 which is released in .NET 4.6.

To change to .NET 4.6 go to: Edit > Project Settings > Player, expand "Other settings" and change the "Scripting Runtime Version" to .NET 4.6

For more info look at: https://docs.unity3d.com/Manual/ScriptingRuntimeUpgrade.html

In Unity 2018, Unity should use .NET 4.x by default so you should have access to interpolated strings without having to change anything.
