Support for the .NET Framework for multi-core hardware

I was commissioned to write a high performance and high availability service that would work in a multi-core box.

Do I need to use the Parellel task library to really use a multi-core server, or will the service work automatically if I type more hardware (cores) on it? Is the .NET platform magic for me under covers?

As a result, will performance be improved by upgrading a server with more cores (keeping the specifications of each individual core the same) for .NET applications that do not use TPL?

According to my understanding (looking through the book of Joe Duffy and his blogs), you really need to program multi-core. Is my conclusion accurate?

It is difficult to answer precisely, since parallel processing is not a common problem. You need to analyze your project to find places where you can use parallel processing.

If your application can be easily broken down into specific independent tasks, parallel processing will definitely improve. If it is mostly serial in nature, several cores / threads will not help at all.

If you have determined that parallel tasks are the core of your process, a parallel library can help you perform basic tasks, as well as simplify getting it.
