Unable to reference EWS Managed API

Question

Trying to use the EWS Managed API 2.0 for my MicroSoft .Net 4.0 (C#, WinForms) application.

I have downloaded the EWS Managed API 2.0 and have added a reference to the Microsoft.Exchange.WebServices.dll in my application from Visual Studio 2010 as required. But I am still unable to include this library with the using statement as follows.

using Microsoft.Exchange.WebServices.Data

Error: The type or namespace name 'Exchange' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)

Screenshot of the error enclosed. Note: For referencing the API, I have followed the instructions in the following MSDN article:
https://msdn.microsoft.com/en-us/library/office/dn528373(v=exchg.150).aspx

Take a look at this link: http://stackoverflow.com/questions/5270484/microsoft-exchange-webservices-is-not-working-in-vs2010 — Sairaj, Jan 22 '15 at 14:29

The target framework of the project needs to be changed from ".NET Framework 4 Client Profile" to ".NET Framework 4" and that will fix this error.

i am bound to use .net 4 client profile fx.. does it means none of the EWS API version is compatible with .net 4 client profile ? – Muhammad Adnan Jul 21 '15 at 17:20
@MuhammadAdnan: Yes, looks like the EWS API cannot be accessed from a program using .Net Framework 4 Client Profile. – prgSRR Jul 29 '15 at 12:46
