How to profile CPU and memory usage from Android C# app while debugging?

I need to make a performance profile of a C # Android application to optimize some processes.
After doing some research on Google, I know that Microsoft Visual Studio has performance profiling features in the Enterprise Edition, and unfortunately, I only have Professional and Community Edition available.

I'd like to know where my code is less performative to optimize.

There's Benchmark.net package but it can be rather difficult to get into at the beginning.
You can also create an extention method that acts on Actions(T) and returns stopwatch.elapsed value
