What is Attribute Programming? What are attributes? Where are they used?

  
Attributes are a mechanism for adding metadata, such as compiler instructions and other data about your data, methods, and classes, to the program itself. Attributes are inserted into the metadata and are visible through ILDasm and other metadata-reading tools. Attributes can be used to identify or use the data at runtime execution using .NET Reflection. (More...)

What are Attributes?

  
An Attribute is a declarative tag which can be used to provide information to the compiler about the behaviour of the C# elements such as classes and assemblies.
C# provides convenient technique that will handle tasks such as performing compile time operations , changing the behaviour of a method at runtime or maybe even handle unmanaged code.
C# Provides many Built-in Attributes

Some Popular ones are

- Obsolete
- DllImport
- Conditional
- WebMethod

and Many more.
Members please keep on posting more responses providing more In-Built attributes.

What are WebPart properties, and what are some of the attributes you see when declaring WebPart properties in code?

  
WebPart properties are just like ASP.NET control properties, they are used to interact with and specify attributes that should be applied to a WebPart by a user. Some of the attributes you see with ASP.NET 2.0 properties are WebDescription, WebDisplayName, Category, Personalizable, and WebBrowsable. Although most of these properties come from the System.Web.UI.WebControls.WebParts class, ones like Category come out of System.ComponentModel namespace.
(More...)

What deployment mechanism can you use to instigate Code Access Security attributes for your WebParts?

  
SharePoint solution files can add in order to handle code access security deployment issues. This is done in the element in the SharePoint solution manifest.XML, which makes it easier to get assemblies the appropriate permissions in order to operate in the bin directory of the web application.

What are attributes?

  
There are at least two types of .NET attribute. The first type I will refer to as a metadata attribute - it allows some data to be attached to a class or method. This data becomes part of the metadata for the class, and (like other class metadata) can be accessed via reflection.
The other type of attribute is a context attribute. Context attributes use a similar syntax to metadata attributes but they are fundamentally different. Context attributes provide an interception mechanism whereby instance activation and method calls can be
pre- and/or post-processed.

What are Attributes?

  
Attributes are declarative tags in code that insert additional metadata into an assembly. There exist two types of attributes in the .NET Framework: Predefined attributes such as Assembly Version, which already exist and are accessed through the Runtime Classes; and custom attributes, which you write yourself by extending the System.Attribute class.
Example - Custom Attribute for entire assembly
1. using System;
2. [assembly : MyAttributeClass] class X {}

what is the use of XMLType attributes?

  
To Specify the Name and Namespace of the XML Type (More...)

Which set of definitions, HTML attributes or CSS properties, take precedence?

  
CSS properties take precedence over HTML attributes. If both are specified, HTML attributes will be displayed in browsers without CSS support but won't have any effect in browsers with CSS support. (More...)

What is mean by XML Attributes?

  
Attibutes provide Additional Information about an Element.
XMl Attributes must be quoted. it's single or Multiple. (More...)

What is mean by Attributes?

  
Attributes provide extra information about elements.Attributes are always placed inside the opening tag of an element. Attributes always come in name/value pairs.
i.e: (More...)

Why should we avoid XML Attributes in XML Document?

  
attributes cannot contain multiple values (child elements can)
attributes are not easily expandable (for future changes)
attributes cannot describe structures (child elements can)
attributes are more difficult to manipulate by program code
attribute values are not easy to test against a DTD
