Breakpoints don't work while debugging native Android library in Visual Studio 2015

Question

On a fresh installation of Visual Studio 2015 I created an Android application and Android native library. Functions from native library are referenced in the app code through DllImport directives.

When I select "Xamarin debugger" for main app and start debugging, I am able to stop on breakpoints in C# code, but debugger doesn't step into native function calls.

When I select "Microsoft debugger" breakpoints don't work at all. During debugging session all breakpoints are marked as disabled and when I point to them the following message occurs:

The breakpoint will not currently be hit. Module containing this breakpoint has not yet loaded.

What do I need to do to debug native Android libraries in VS2015?

SOLUTION:

And we were right! The issue is related to Hyper-V on Windows 10 when running on the latest Intel (Skylake) processors. (Thanks Mike, from the VS Android Emulator team, who suggested this possible workaround).

Hot to Fix it:

• In the Hyper-V manager, right click on the Android VM you are using.
• Click Settings
• Expand "Processor", select "Compatibility"
• Enable "Migrate to a physical computer with a different processor version"

You can see below the checkbox you have to select.
