I am following the Working with Data in LightSwitch (Guided Tour) at http://msdn.microsoft.com/en-us/library/ff851982.aspx, and at the "Connecting to Data" portion I am unable to choose "OData Service" in the Attach Data Source wizard. It just doesn't appear. See attached. What do need I to do to get "OData Service" to appear, so I can choose it? Thank you! - tom

Thanks for help on this, Looking at moving from Access and I'm impressed with the deployment possibilities of LS along with the RAD focus (great name too - Lightswitch). Struggling with something that I'm sure is simple but I'm missing - how do I add a column/field to a query or a datagrid from a related table in LS.  I've tried adding a Data Item in a screen, bit I can't add a field to the grid, and there doesn't seem to be any options to add fields in the query builder. What am I missing folks? Brad

I have a very big problem.  I created and published a LS application - VS2012 and got this error is generating the program with both the web client mode and desktop clients.  I started this post because I unsuccessfully tried all the solutions I've found on the internet. My application is 3 tier levels  In particular: the IIS server is Windows 2008R2 and is within a domain with multiple servers. The database is on another server Windows 2008R2 with SQL Server 2008R2.  The Lightswitch IIS server has been configured using the Web Platform Installer 4.5  As mentioned on various blogs:  - On IIS7 I checked authorization, first anonymous ASP only, then with authorization Form  - I tried to do the repair of the framework 4.0 and restart both the Web server (Web mode) and the client (in desktop mode)  - I plugged in the web.config section:    <system.webServer>

Hi, my app created with VS2012 has silverlight client with forms authentication and I am trying to web-deploy to IIS server with database and client on same machine. Until now I was reading so many tutorials and watched many different tutorial-videos. So far I managed to deploy my website to the server without any errors in VS. am I ready now? however, if i try to start my app I use the link http:  / / <serveripv4> / <myappname> but I get "Server error 403 forbidden". I look inside the directory on the Server C:\inetpub\wwwroot\<myappname> and find a subdirectory "Client" with a file default.htm I am wondering what is the right lik to my app? If I use the link http:  / / <serveripv4> / <myappname> / Client I get the loading-percentage-view and at the end I get "error in database communication" it seems to me the database was not created at all. SQL Management Studio does not show the database and
