Hi All,

I have gone through some MVVM videos and articles, but I would like to have some sort of video or document to see how should I use MVVM in sharepoint online development.

Much appreciate if someone can explain with some sort of code that is relating to SP online Development.

Answer 1

In SharePoint online the custom code can be deployed through SharePoint 2010 Sandbox Solutions. In Sandbox Solutions, there is no special project type in Visual Studio 2010 for creating Silverlight MVVM applications. You can create a blank SharePoint 2010 Sandbox Solution Project Type and add

the relevenat assemblies of Silverlight MVVM applications and deploy it to the Solutions gallery of site-collection and activate it. Then you can

add Silverlight .xap files to the document library or any relevant library at Site-Collection level and invoke this using Silverlight web part. Please be aware of Sandbox Solutions restrictions before implementing functionalities in side MVVM application.
