 Q. What’s New with SharePoint Web Parts?

A developer can create two types of web parts using Visual Studio 2010.

     1.       Visual Web parts - Allows you to Drag and Drop the controls from the Toolbox to Web Part Design surface. You can of course write your custom code in the code file. You can also package and deploy your web parts directly to SharePoint from VS by pressing Clt+F5. Visual studio 2010 also provides you with three different views for developing web parts. The views are split view, design view and Source view (as we have in designer 2007).
Note: The Visual Web part project Item basically loads a User Control as a Web Part.                                          
2.   ASP.Net Web Parts - Where a developer can build up User Interface and logic in a class file. You do not have designer for drag and drop of controls. This web part inherits from standard ASP.Net web part. For Deployment we can again use ctrl+f5 to deploy this web part.

Q. What are Requirements for SharePoint 2010?

Q. What is LINQ? How is it used in SharePoint?

 Ans. LINQ is a feature of the programming languages C# 3.0 and Visual Basic .NET. LINQ allows you to query in an object-oriented way, supports compile-time check, gives you intelligence support in Visual Studio and defines a unified, SQL like syntax to query any data source. But unlike other languages and query syntaxes which vary from one type of data source to another, LINQ can be used to query, in principle, any data source whatsoever. Hence, developers may find that it is the only query syntax that they ever need to know. It is commonly used to query objects collections, XML and SQL server data sources. LINQ to SharePoint is officially being supported with the 2010 release. It works similar to LINQ to SQL or LINQ to Entity. The LINQ to SharePoint Provider is defined in the Microsoft.SharePoint.Linq namespace. It translates LINQ queries into Collaborative Application Markup Language (CAML) queries. The gateway class for the LINQ to SharePoint provider is Microsoft.SharePoint.Linq.DataContext which represents the data of a SharePoint Foundation Web site.
