Integrating CRM 2011 Online and SharePoint 2013 Online using BCS oData Proxy

Here we will be creating an ASP.NET Data Service and host it in azure. This ASP.NET Data Service will be used to generate BCS Model in SharePoint 2013 online. The service will allow basic CRUD operation on Contact record in CRM 2011 from SharePoint 2013 online.

• Create a new Windows Azure Cloud Service project in VS 2012

• Select WCF Service Web Role

• Remove the System.Data.Services.Client.dll from the References

• Add a new item ASP.NET Data Service to the WCFServiceWebRole1 project

• Add a new class to the project

• Specify the class name in the ASP.NET Data Service class

• Add references to the following dll’s

1. Microsoft.crm.sdk.proxy
2. Microsoft.xrm.sdk
3. Microsoft.IdentityModel

• Set Copy Local as true for the Micrsoft.IdentityModel

• Source Code for CrmContext.cs, for CRUD Operation (we need to implement IUpdatable Interface for CRUD)

 }
}

• Test the service in browser

• Create a new SharePoint App project in Visual Studio

• Right click the App Project and select the option “Content Types for an External Data Source”

• Specify the URL for the WCF Data Service and give a Data Source Name and select Next

• Select the Contacts data entity

• Deploy the app

• Get the URL where the app is installed

• Append the External List path to the URL

• The Contact records will be displayed in the list in SharePoint.

• The list item also support update and delete operation

Hope it helps.
