How To Export ADFS 2.0 Metadata XML File

In ADFS (Active Directory Federation Services), Relying Party Trusts can be configured manually or using metadata file.
Manually creation of a Relying Party Trust requires lots of details to be input, which is obtained from the partner organization. These details include URLs, relying party identifiers, certificate etc. Which may lead to misconfiguration or Typos.
You can use metadata xml file, which includes all required information and it is easier to import & export as well.
