in new line of work have been told avoid using extension methods types (or organization) have no control over, meaning external libraries, framework types such string, list, , others. the argument given bad if framework developer decides implement method has same names and/or parameters extension method. while problem may arise, argument reduces usability of extension methods zero. argument considered valid? not suggesting use extension methods everywhere, know of similar arguments , against it. it's argument has some merit, in lots of cases problems can avoided: if control code , can update if necessary, can write unit tests detect problem , correct if occurs. (i assume you'd validating update external library before deploying anyway.) if trust external library developer follow normal practices backward compatibility, shouldn't adding members interfaces anyway, break existing implementations... @ least write extension methods interfaces. if extensi...

i'm working on implementing streaming client takes audio , video streamed server on user's local network , renders in real-time. i've been using mediaelement handle receiving stream: <mediaelement x:name="mediaelement" autoplay="true" source="{binding streamuri}" /> we need mediaelement responsive possible. user on client can send commands streaming server can alter contents of stream, , able show user results of change immediately. however, there seems hard-coded buffer length of 5 seconds, resulting in constant 5-second delay between user's action , result. is there way can reduce or eliminate buffering time? i've found mediaelement.bufferingtime property, seems exist in silverlight , windows phone 7. (for legacy reasons, have use windows 8 instead of upgrading windows 8.1.) the property realtimeplayback of mediaelement reduces delay of stream playback: mediaelement media = new...

the documentation says : what happens when maximum number of stored requests reached (by default 25)? internally store requests in fifo queue. means when maximum number spaces in queue filled, take first 1 entered , remove queue, making room new request. how increase limit of 25? want use glimpse gather data , dig diagnose after 30 users in 30 minutes session there lot more requests 25. due boneheaded mistake, me, number of requests glimpse stores, supposed configurable, isn't. the offending line can seen in our implementation of applicationpersistancestore . your best bet running build glimpse (very easy do) , change buffersize whatever see fit. alternately, implement own ipersistancestore , have whatever you'd like.
