2. About Me http://about.me/talbott Solutions Architect at ThirdM A Founder of SharePoint Saturday Boston Microsoft MVP Blogger and Author 3. About this Talk For Developers Who want to build Apps For SharePoint For Architects Who want to understand options and architecture considerations ofa Provider Hosted App For Anyone Who wants to learn more about SharePoint 2013 and the future ofExtending and Customizing SharePoint 4. What is a Provider Hosted App SharePoint 2013 Compatible Application Hosted outside of SharePoint Azure Amazon Web Services (AWS) Rackspace Your Datacenter An on-premise server in your customers Datacenter (you providethe Application, Hardware, and/or VM) Written in any language on any platform Java, F#, Ruby, Linux, Unix 5. App Development History SharePoint 2003 Web Parts SharePoint 2007 Farm Solutions & SPD WSP (A CAB file with deployment assets and instructions) which may include: Server Code (.NET Assemblies for GAC or BIN) Client Code (JavaScript Files, CSS, HTML) ASP.NET (ASPX, ASCX, Master Pages), Images, Site templates, List definitions, Content Types (CAML), Layouts, various other types of content SPD (SharePoint Designer) Create custom solutions with Workflows, JavaScript, HTML, jQuery, Master Pages, Layouts stored in Content Database SharePoint 2010 Sandbox Solutions SharePoint 2013 Apps for SharePoint 6. Apps for SharePoint Hosting Options Provider Hosted Apps SharePoint 2013 on-premise or Office 365 Unlimited scaling Autohosted Apps Typically Azure Web Sites written in .NET Runs only in Office 365 (no on-premise option) Uses the consumers Office 365 Azure resources SharePoint Hosted Apps Client side only (JavaScript, jQuery, HTML, CS S) Uses CSOM to manipulate SharePoint object http://bit.ly/spapphosting 7. Provider Hosted Apps Office 365 Data Center Application Runtime and Backendor On-Premise SharePoint 2013 Farm (Can be anywhere: On-Premise or Cloud) ProviderSharePoint Provider2013 Hosted Service app Provider Data CustomerProvider 8. Alternative Using AutohostedOffice 365 Data CenterApplication Runtime and Backend (including Azure)(Cloud Service you Host) Office 365Autohosted appProvider(SharePointWindows AzureOnline) Service Azure DatabaseCustomer Data Provider DataCustomer Provider 9. Provider Hosted Architecture Store or App Catalog Deployment Manifest .APP file App Manifest Declare App Permission Requests Trust Settings User must allow or trust your app Provider receives Request with Trust Token Provider uses CSOM to call back to SharePoint using theTrust Token SharePoint persists changes made by the Provider in theContent Database (just like SharePoint Designer) 10. Costs of Being a Provider Need to maintain and cover hosting cost But you can extend your app to other ecosystems outside ofSharePoint iPad, Facebook, Kindle, Salesforce Changes will affect ALL customers May need a versioning strategy for customers in Life Sciences(long validation lifecycle) 11. Benefits of Provider Hosted Does not tax the SharePoint Farms resources as muchas Farm Solution might Update 1000s of SharePoint Farms with one releaseupdate to the Provider Centrally managed at the Providers location Develop on any platform using any language leveragingyour existing developer and infrastructure knowledge Same App works on Office 365 and SharePoint 2013 on-premise 12. Development Model Get Started using Azure and Office 365 Preview Many Blog posts on getting started Deploy your Provider Hosted app to your Provider(Azure, AWS, Rackspace, local server) Deploy your .APP file to SharePoint 13. Development System Requirements Visual Studio 2012 On Premise Development Environment http://bit.ly/spappdevenv Office Developer Tools for Visual Studio 2012 http://bit.ly/spapptools 14. Decisions Office 365 or On-Premise? If Office 365, Visual Studio 2012 If On-Premise then build your SharePoint 2013 Dev Server Windows Server 2012 or Windows Server 2008 R2 SP1 http://msdn.microsoft.com/en-us/library/fp161179.aspx http://msdn.microsoft.com/en-us/library/fp179923.aspx 15. App Packaging Start with Visual Studio 2012 Project Template .APP Contains AppManifest.xml Set Permission Requests for your App Start Page Client ID App Icon Image File You can unpack the .APP by renaming .ZIP 16. Demo Using Visual Studio to create the App Manifest Explore Contents 17. Security Client Secret vs Certificate Client Secret requires SharePoint is farm connected to ACS Azure ACS (Access Control Service) Office 365 is already connected to ACS AppManifest.xml (.APP) Contains permissions OAuth TokenHelper.cs (runs on the Provider) Helps you manage requests for app tokens If you are developing in another language you will need to implementthis yourself 18. OAuth ExampleTokenHelper.TrustAllCertificates();string contextTokenString =TokenHelper.GetContextTokenFromRequest(Request);if (contextTokenString != null) {contextToken =TokenHelper.ReadAndValidateContextToken( contextTokenString, Request.Url.Authority);sharepointUrl =new Uri(Request.QueryString["SPHostUrl"]);accessToken = TokenHelper.GetAccessToken(contextToken,sharepointUrl.Authority).AccessToken;CSOM.CommandArgument = accessToken;} 19. CSOM Client Side Object Model Rich improvements over 2012 .NET version JavaScript version http://bit.ly/csom2013 20. CSOM Exampleprotected void CSOM_Click(object sender,EventArgs e) {string commandAccessToken =((LinkButton)sender).CommandArgument;RetrieveWithCSOM(commandAccessToken);WebTitleLabel.Text = siteName;CurrentUserLabel.Text = currentUser;UserList.DataSource = listOfUsers;UserList.DataBind();ListList.DataSource = listOfLists;ListList.DataBind();}http://bit.ly/spappbasic 21. CSOM ExampleClientContext clientContext =TokenHelper.GetClientContextWithAccessToken(sharepointUrl.ToString(), accessToken);//Load the properties for the web object.Web web = clientContext.Web;clientContext.Load(web);clientContext.ExecuteQuery();//Get the site name.siteName = web.Title;//Get the current user.clientContext.Load(web.CurrentUser);clientContext.ExecuteQuery();currentUser = clientContext.Web.CurrentUser.LoginName;//Load the lists from the Web object.ListCollection lists = web.Lists;clientContext.Load(lists);clientContext.ExecuteQuery(); 22. Scope of Access What can you get to from CSOM? 23. Putting it all together Generate Client ID and Client Secret Generated by form on SharePoint Online https:///_layouts/15/appregnew.aspx APP Manifest and Icon packaged in .APP file Includes Permission Requests Includes Client ID Deployed to SharePoint Your app is deployed to Azure, etc ClientID and ClientSecret Your app receives Token from SharePoint user request Your app uses Token to call CSOM 24. Review SharePoint has completely new Development Model Leverage existing understanding with CSOM Leverage existing other technology knowledge Update many customers (or Farms) at once Costs and Benefits of being a Provider Security with OAuth Package and Deploy to Store 25.
