Some time we need to check requirement level of specific attribute\u00a0in run time, this can be done using metadata webservice. For example I am taking accountnumber attribute of account entity, I have changed it\u2019s Requirement level to Business Required for my demo purpose so let\u2019s check through code, I have created a website project in Visual studio with default aspx form and a\u00a0command button on it, as metadata webservic reference to your website project.
