SPWebService.ContentService returning System.NullReferenceException

Home | SharePoint Development | SPWebService.ContentService returning System.NullReferenceException

When I tried to access SPWebService.ContentService in the following code-snippet (executed inside a console application), I was getting Null value.

 SPWebService contentService = SPWebService.ContentService;
            contentService.ClientRequestServiceSettings.MaxReceivedMessageSize = -1;

            SPWcfServiceSettings csomWcfSettings = new SPWcfServiceSettings();
            csomWcfSettings.MaxReceivedMessageSize = 104857600; // 100MB
            contentService.WcfServiceSettings["client.svc"] = csomWcfSettings;


The resolution is to change the target CPU type in the Build properties from X86 to X64 or AnyCPu Type. That fixed my issue.
