Difference between PCL and ClassLibrary

PCL

  1. Portable class libraries are platform independent
  2. They do not use conditional compilation and unmanaged code, they have no UI inside (UI is platform dependent)
  3. This is because PCL should work on all specified platforms which was chosen as a target. Also, availability of features depends on selected targets. PCL can be referenced by any project which target is specified in the PCL settings.


Class Library
  1. Class Libraries are not platform independent.
  2. No conditional compilation, they too have no UI inside.
  3. Class Libraries of other types can be referenced only by projects which have the same target or by upper subsets of .Net

Generic Interface and Factory Pattern in C#

There could be several ways to achieve it. I'll be highlighting three different ways to achieve it First: using strongly type public static class GenericFactory { public static IGeneric < T > CreateGeneric < T >( ) { if ( typeof (T) == typeof ( string )) { return (IGeneric<T>) new GenericString(); } if ( typeof (T) == typeof ( int )) { return (IGeneric<T>) new GenericInt(); } throw new InvalidOperationException(); } } You would use it like this: var a = GenericFactory.CreateGeneric< string >(); var b = GenericFactory.CreateGeneric< int >();  Note that this uses a strongly-typed call rather than passing in the type name as a string (which may or may not be what you actually want). Second: using object If instead you want to pass a string for the type name, you will have to return an  object  because there is no way to return th...

How to get device info IMEI programmatically in xamarin android

You'll need the following permission in your  AndroidManifest.xml : <uses-permission android:name="android.permission.READ_PHONE_STATE" /> in order to do this.
