System.MemberAccessException due to AssemblyCompany not set in AssemblyInfo.cs

[jaderfeijo]

While trying to check whether or not a folder exists from a PCL library through a Unit Test target via SpecialFolder.Current.Cache.CheckExistsAsync("MyFolder") I get the following exception being thrown, which cases my unit test to fail:

System.MemberAccessException : There is a need to set a valid value to AssemblyCompany of AssemblyInfo.cs.

I just ran into this as well while NUnit testing. Error happens at PCLStorage.FolderPathImplementation.get_CompanyName(). Since all my AssemblyInfo's have a company name, it must be the NUnit object that somehow needs to get the label. ;P Any tips much appreciated.
