SharePoint’s New App Model To highlight the new app model briefly, Microsoft has: Completely separated custom server-side code from SharePoint in order to protect SharePoint’s core code from extra resource intensive processing. Unlike web parts, no server-side app code runs on SharePoint’s server. In return, Microsoft has made a HUGE investment in providing service- based methods for exposing SharePoint’s object library to code running on other servers.
SharePoint’s New App Model From a GUI perspective, apps appear: Within iFrames inside of SharePoint pages using App Parts OR As full web sites running on a different server using SharePoint’s available client-side libraries and web services to bring in SharePoint’s design theme. In either case, your app’s server-side code does not run in SharePoint Your app’s server-side code can either run in an auto-hosted Azure space, or on your own server infrastructure, via the provider-hosted app model. For the purposes of this presentation, we’ll focus on the latter
Why choose the Provider-Hosted hosting method? Your app might need to run behind a corporate firewall; for whatever reason, hosting it in the cloud is a no-no. Your app’s server-side code is PHP, JSP, etc… SharePoint 2013 is just one of many clients for your web application You just like the control of directly running your own app
Assumptions for this presentation You have a SharePoint 2013 Office 365 Developer Site: Free 30 Day Trial Available, $100 a year afterward http://msdn.microsoft.com/en-us/library/fp179924.aspx http://msdn.microsoft.com/en-us/library/fp179924.aspx Free for MSDN Premium and Ultimate Subscribers Can be provisioned from Office 365 E1 or E3 plans You have Visual Studio 2012 Professional or higher installed, and Microsoft Office Developer Tools for Visual Studio 2012 You have at least Visual Studio 2010 or higher to upgrade the codebase of your existing web application
Assumptions for this presentation Your existing web application: is at least a.NET 4.0 web application Uses some form of internal users database table to manage accounts We’ll be syncing this later with the Office 365 account
SharePoint Site Setup Some initial setup steps to do on your SharePoint site
Create an App Catalog Site Click Admin on the top menu and then click SharePoint in the dropdown Click apps on the right sidebar Click App Catalog under apps. SharePoint will guide you though creating your App Catalog Site if you don’t already have one
Use appregnew.aspx to create a client secret based relationship with your app /_layouts/15/appregnew.aspx /_layouts/15/appregnew.aspx
Use appregnew.aspx to create a client secret based relationship with your app This method does not support multi-tenant uses of your app Use the Microsoft Seller Dashboard if you want to “sell” your app to multiple SharePoint installations Your app Domain will need to include a specific port number if it won’t be running on a standard SSL port. Make sure you write down the information created. It will be necessary when packaging your app.
Building Your App In Visual Studio 2012 How to build your on-premise app
Create your app in VS2012 - I Specify your SharePoint 2013 site Make sure your select “Provider-hosted” for where you want to host your app.
Create your app in VS2012- II Specify Use client secret when setting up authentication
Create your app in VS2012- III Your new solution contains two projects: The SharePoint 2013 App project A matching web application project that Visual Studio assumes will be your provider hosted app. For the purposes of this walkthrough you can ignore it.
In your appManifest.xml file, specify the start page of your app
Then update the code of your AppManifest.xml file to include your client ID.
Add an app part to embed an interface inside a SharePoint page
Now Publish your app to create an.app file. You’ll be asked for your Client ID and Secret. Enter them in the wizard. Also, specify the website your app will be hosted it’s OK to specify an SSL address that doesn’t exist. For our method of deployment, it doesn’t matter
Publish your app to SharePoint Make it available for your site collections
Upload your app file to the SharePoint developer site. Go to your App Catalog Site, and click the Distribute apps for SharePoint tile
Upload your app file Click new app, and upload the.app file the Visual Studio publishing tool created. After the upload, add any additional information for your catalog entry:
We’re half done!!! Now we need to make your web application talk to SharePoint
Install the SharePoint Server 2013 Client Components SDK http://www.microsoft.com/en-us/download/details.aspx?id=35585 http://www.microsoft.com/en-us/download/details.aspx?id=35585 Install it on the web server that will be hosting your provider-hosted app Also, install it on any development workstations that do not have Visual Studio 2012 installed, but will be used to update the web application’s code.
Also install Microsoft Identity Foundation http://www.microsoft.com/en-us/download/details.aspx?id=17331 http://www.microsoft.com/en-us/download/details.aspx?id=17331
In your Visual Studio web project, add.. TokenHelper.vb or TokenHelper.cs Can be cut and pasted from the Visual Studio 2012 app project. Should also be available online Also add the following references Microsoft.IdentityModel – Set Copy Local to true Microsoft.IdentityModel.Extensions – Set Copy Local to true Microsoft.SharePoint.Client – Set Copy Local to true Microsoft.SharePoint.Client.Runtime – Set Copy Local to true System.IdentityModel System.Web.Extensions System.ServiceModel System.Web.Extensions
Add your ClientId and ClientSecret to the web.config file of your application The default TokenHelper code reads these Now that both your SharePoint App and your Web Application have them, there is a basis for them to trust each other!
On the start page of your app, determine the user’s identity Leverage this against your user’s table to determine the user accessing your site
Feel free to alter TokenHelper… For one of our apps, we made a version that can be instantiated, with the client settings then loaded in from a database. This approach allowed for multiple SharePoint apps to work off the same web application. Update reference code is attached to this slide.
You should now have a fully authenticated SharePoint 2013 app! Although, it looks nothing like SharePoint probably…
Use the Chrome Control Bring a bit of SharePoint 2013 into your app http://msdn.microsoft.com/en-us/library/fp179916.aspx
Update your web application’s GUI Code Minimize how your application’s style sheet interferes with SharePoint’s style sheet. Use my ThemeHelper class to bring SharePoint colors into your style sheets http://go.limeleap.com/community/bid/287707/How-to-Easily-Bring-SharePoint-2013- Theme-Colors-Into-Your-Apps http://go.limeleap.com/community/bid/287707/How-to-Easily-Bring-SharePoint-2013- Theme-Colors-Into-Your-Apps This is a HUGE timesaver if it can be assumed your App will have Manage rights for the SharePoint site If Your Have More Time…. Adopt SharePoint styles instead of using your web application’s styles so that your application’s design changes properly when an end-user changes their SharePoint theme. See if the overall layout of your web application fits SharePoint’s Modern UI look and feel.
Let’s dive into some code! A look at how Authentication is working, the Chrome Control, and ThemeHelper!
Summary It doesn’t take long to get a legacy.NET application connected to a SharePoint 2013 Office 365 site, complete with seamless authentication You can enjoy the relative inexpensiveness and availability of a SharePoint 2013 Office 365 site, while pulling in legacy applications hosted elsewhere The price for each Office 365 E1 user is only $8.00 a month, and also includes Hosted Email, Office Web Apps, Lync, Skydrive Pro We really haven’t touched the surface of what SharePoint apps can actually do with the SharePoint object model. All we did was authenticate, but there’s tons more available via the SharePoint.Client library
