Using .Net framework 4. I am assuming this log4net version that the PayPal library is dependent on
requires an older version or I don’t have the file at all? Do I need to get this file somewhere or
is there another work around ?

Update, after installing latest version of log4net I now get the same error except the file is found
this time and says**:

 The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)]
   com.paypal.sdk.profiles.BaseAPIProfile..cctor() +0




Line 23:        {
Line 24:            NVPCallerServices caller = new NVPCallerServices();
Line 25:            **IAPIProfile profile = ProfileFactory.createSignatureAPIProfile();**

code.
