Example Project

**Overview:**

Referencing a netstandard project in VS 2017 (the new .csproj format) causes a build error. 
 
**Steps to Reproduce:** 

1. Build the attached iOS project in VS 2017.


**Actual Results:**

Build Error: 

The "ConvertPdbToMdb" task failed unexpectedly.
Pdb2Mdb.PortablePdbNotSupportedException: Portable PDB 'c:\users\johmil\documents\visual studio 2017\Projects\NetStandardTest\ClassLibrary1\obj\Debug\netstandard1.6\ClassLibrary1.pdb' can't be converted to mdb. Consider setting the project 'DebugType' property to 'Full'.

**Expected Results:**

 No build errors. 
 
**Build Date & Platform:**

 Microsoft Visual Studio Enterprise 2017
Version 15.0.26228.4 D15RTWSVC
Microsoft .NET Framework
Version 4.6.01586

Installed Version: Enterprise

Xamarin   4.3.0.784 (73f58d6)
Visual Studio extension to enable development for Xamarin.iOS and Xamarin.Android.

Xamarin.Android SDK   7.1.0.41 (9578cdc)
Xamarin.Android Reference Assemblies and MSBuild support.

Xamarin.iOS and Xamarin.Mac SDK   10.4.0.123 (35d1ccd)
Xamarin.iOS and Xamarin.Mac Reference Assemblies and MSBuild support.

**Regresion status:**

This does not appear to be a regression. 
 
**Additional Information:**

This seems related to the new portable PDB files being used in these project types.
