1. Open Visual Studio 2010 , GO to File --> New --> Project or (ctrl+shift+N).

2. Select SharePoint --> 2010 under Installed Templates which on left handside.

Then Select ContentType and name the project Here i am naming it as "EmpContentType". And Click on 'OK'.

3. Now it will open SharePoint Customization Wizard, in this specify 'What local site do you want to user for debugging' here it is "http://demoshare:6969" and 'what is the trust level for this SharePoint Solution' here am choosing Farmlevel so it is Deploy as a farm solution.
Then click 'Next'.



4. Here we need to choose 'Which Base content type should this content type inherit from' i.e parent Content Type, Here am selecting 'Document'. Now Click on 'Finish'.



Note: <ContentType ID="0x010100df9cc96d389c439dba13a1b6fd2bd431"> in this 0xO101 is specify parent content type and then 'df9cc96d389c439dba13a1b6fd2bd431' is new guid for content type in between these two values '00' is added by default.

Field Name        Type

EmpID             Text
EmpName           Text
EmpDepartment     Choice
EmpAddress        Note
