title: Why is Facebook referenced in TrustFrameworkBase.xml?
body: <p>The <a href="https://docs.microsoft.com/en-us/azure/active-directory-b2c/tutorial-create-user-flows?pivots=b2c-custom-policy" rel="nofollow noreferrer">documentation</a> for Azure AD B2C says &quot;Base file - Few modifications are required to the base&quot;. I expected to change just the TenantId and PublicPolicyUri at the beginning of the file.</p>
  <p>I was surprised to find that a Facebook ClaimsProvider is defined in the base file. Shouldn't that be in TrustFrameworkExtensions.xml? If I don't want to use Facebook, I have to make lots of changes to TrustFrameworkBase.xml.</p>
  <p>I got my TrustFrameworkBase.xml from the SocialAccounts folder of the <a href="https://github.com/Azure-Samples/active-directory-b2c-custom-policy-starterpack" rel="nofollow noreferrer">start pack</a> GitHub repository that is referenced in the documentation. Is there a better place to get a TrustFrameworkBase file?</p>
