WPF JSR168 portlets should work with WSRP, within the limit of what WSRP and WP's support of WSRP allow. Note, WSRP is a portlet standard, so functionality that uses servlets and/or URLs to your portlet WAR outside of the Portlet API may not work, such as AJAX, Content Launch, Excel Export, and Lotus Forms builder support. Also, portlets that make use of certain Portal APIs like PUMA for user/group management/lookups (including WP Group profile selection handler) may not be supported over WSRP. The 1.0 version of the WSRP specification used in the WP 6.0.x WSRP support did not include event handling, so Property Broker events over WP6.0.x WSRP 1.0 isn't supported. For more information on WP support for WSRP, see the following documentation.
