Sure, but I am the opinion it does compose, if one embraces it isn't the same as writing C++ in C#, not trying to downplay your experience on the matter.

For example, here are the Roslyn analysers for a more RAII like experience with IDisposable,

https://github.com/DotNetAnalyzers/IDisposableAnalyzers

Turn "DISP004-Don't ignore created IDisposable." into a compiler error and you have your region allocated RAII like experience.

And moving a bit the goal posts, for those scenarios where C# fails completly to provide a usefull solution, we can rewrite just that module into C++ (preferably C++/CLI when only Windows matters), and have the best of both languages.
