In this article I am explaining the step by step procedure to create a sandbox solution with full trust proxy.Before starting I am assuming you are aware of the sandbox limitations. Full trust solution is providing sandbox solution to work in a full environment. In short this is the way to achieve farm based solution functionality in a Sandbox.Namespace Required:using Microsoft.SharePoint.UserCode;using Microsoft.SharePoint.Security;using System.Security.Permissions;using Microsoft.SharePoint;using Microsoft.SharePoint.Publishing;Step 1: Create a simple sharepoint solution with Sandbox; choose create webpart:Step 2: In the webpart, add the logic for creating the web part:Step 3: Deploy the webpart and see the UI:Step 4: Create a new project under the same solution; give it a name and Click Ok:Step 5: Create two classes under full trust class library. One for ProxyArg and the other for ProxyOperation.Step 6: Add the reference to the Fulltrust code in webpart like below:string st= SPUtility.ExecuteRegisteredProxyOperation(assemblyName,typeName, new ProxyArg(URL, txtEnter.Text)).ToString();Step 7: Add the code logic and deploy the solution. Put the solution GAC and take the reference in Webpart solution.Step 8: Use the attached powershell script for registering the full trust code in sandbox solution. Deploy the webpart.It will look like below:And you can check the page library also:That's it. We are done with our solution. Hope you like this article.
