if there is Braces before method or property. what does that mean.

[Column]

public string ContactInfo

if possibel give some examples

That means your adding attributes so that you can have runtime logic to interpret those attributes.

One of the attributes are [Obsolete] which is attribute that adds information to the member or class on which its is decrated.

Take for example i want to build a sql statement out of my class i can create attributes like Column, Table , Where etc and decorate them to my class and properties and in runtime construct the sql statement based on these attributes.

It is an attribute.

In Webservice , it is a webmethod.

The thing that you mention over a Method / Function as you mentioned are called 'Attributes'

For Example,

[Browsable(false)]
Public Shared Sub A()

         //Some Code

End Sub

The [Browsable] will take care of Showing / Hiding the contents, when you say 'Go To Defenition'.
