Q. Whats New with SharePoint WebParts?
A developer can create two types of webparts using Visual Studio 2010.
1. Visual Webparts - Allows you to Drag and Drop the controls from the Toolbox to WebPart Design surface. You can of course write your custom code in the code file. You can also package and deploy your webparts directly to Sharepoint from VS by pressing Clt+F5. Visual studio 2010 also provides you with three different views for developing webparts. The views are split view, design view and Source view(as we have in designer 2007).
Note : The Visual Webpart project Item basically loads a User Control as a WebPart.
2. ASP.Net WebParts - 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 webpart inherits from standard ASP.Net webpart. For Deployment we can again use ctrl+f5 to deploy this webpart.

This means that the existing sites\pages or components will not be effected by the newly added soultion.

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 intellisense 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.
