c# - How to "extend" query in Lightswitch? -

-

i need present data 2 tables in same view. when use calculated property performance penalty not acceptable.

if have done using sql possible using join. know how using linq , entity framework.

the problem lightswitch lets me execute queries results in list of existing entities.

i'm creating desktop client.

if correct relationships have been set up, possible data items multiple entities displayed concurrently solely using built in queries. question doesn't have enough detail know whether work here, it's best way go if can keep benefit of other automagical lightswitch features.

if it's not possible using built in queries or want change shape of data , not return lightswitch entities, use wcf-ria service. sounds approach here leverage linq knowledge too.

http://lightswitchhelpwebsite.com/blog/tabid/61/entryid/2226/creating-a-wcf-ria-service-for-visual-studio-2013.aspx covers how in vs2013. it's 1 of things sounds complicated @ first ok if follow carefully.
