Currently, on the first build of a "Hello World" Xamarin.Forms app,
you will see this in the build log:

_ConvertedDebuggingFiles

C:\Users\myuser\.nuget\packages\xamarin.forms\3.1.0.697729\lib\MonoAndroid10\Xamarin.Forms.Platform.Android.dll
The logging is a little weird here, but this `ConvertDebuggingFiles`
MSBuild task takes about 100ms on my machine.
What is it doing?
The Mono debugger can support two types of debugging files:
- `mdb` files
- "portable" `pdb` files
If Xamarin.Android's build finds a "non-portable" `pdb` file, we have
to run it through this task to convert to an `mdb` file... This gives
us proper stacktraces for `FormsViewGroup.dll` and
`Xamarin.Forms.Platform.Android.dll`.
You can change the type of debugging symbols in your project with the
`DebugType` setting, which has these options:
- Blank or `None`: don't generate symbols. (Although Xamarin.Android
has funny behavior here, see:
https://github.com/xamarin/xamarin-android/issues/2282)
- `Full` generates an `mdb` file, this is a Windows-proprietary format
for debug builds
- `PdbOnly` generates a "non-portable" `pdb` file, a
Windows-proprietary format for release builds
- `Portable` generates a "portable" pdb file, which is the new
standard that works for debug and release builds. New SDK-style
MSBuild projects use this option by default.
These values are not case sensitive, I have mostly seen them lower
case in newer projects.
So what does Xamarin.Forms need to do?
Use `<DebugType>portable</DebugType>` in any Android class library or
app project. Other platforms, this is optional, not as much benefit. I
have heard that `DebugType=portable` might cause a problem on UWP.
* Xamarin.Forms will ship "portable" `pdbs` in its NuGet package for
`FormsViewGroup.dll` and `Xamarin.Forms.*.Android.dll`. Developers
won't pay the 100ms on initial build.
* Initial build times for `Xamarin.Forms.sln` will be slightly better
for development, although I didn't measure the difference here.
