Windows Azure App Fabric Team has released updated version of Windows Azure App Fabric with following update:
The following updates have been made to all ACS 2.0 namespaces.
In the initial release of ACS 2.0, the character encoding set for all HTTP responses from the OAuth 2.0 endpoint was US-ASCII. In the July 2011 release, the character encoding of HTTP responses is now set to UTF-8 to support extended character sets.
The previous quotas on configuration data have been removed in this release. This includes removal of all limitations on the number of identity providers, relying party applications, rule groups, rules, service identities, claim types, delegation records, issuers, keys, and addresses that can be created in a given ACS namespace.
