architecture - WCF / WCF Data Services / WCF RIA Services -

-

not add post regarding different wcf stacks, want make sure i'm heading in right direction before waste more development time...

my scenario - our company has number of web apps access same series of databases. apps developed independently, there's ton of business logic , data access repetition. on top of that, have (possibly unreasonable) goal of making project client-independent - consolidate our current business logic , data access interface can accessed web app, silverlight, mobile app, etc.

enter wcf - strikes me perfect option accomplish both. unfortunately, after reading existing "guidance" exists on various wcf flavors, keep coming more confused anything. here conclusions i've come far - please feel free correct me:

  • straight wcf - flexible , comprehensive option, starts scratch; require significant time front configure , test; technically mature option hooks accomplish of goals
  • wcf data services - fastest way of getting rest service online; excellent if application needs expose data directly db; if business logic needed, either must written on client side or second service exposes logic.
  • wcf ria services - fastest way configure service ready expose business logic; possibly technically immature of options (but looks significant investment bring along); soap, rest, , json endpoints allow of client independence;

so given requirements above, i've come following conclusions - data services non-starter due business logic requirements (and idea of second wcf service consuming data service strikes me extremely poor architectural choice); speed matters, indicate ria services might best place start (call me lazy, having small team tight timeframe makes code generation valuable).

is there better way handle goals described? misunderstanding any/all of wcf options? other practical guidance can offered choosing wcf approach (not me, else trying evaluate technologies)?

i go straight wcf.

this allows expose services through various endpoints depending upon requirements:

  • soap cross platform interopability
  • binary nettcp internal clients requiring speed
  • json lightweight access

c++ - Compiling static TagLib 1.6.3 libraries for Windows -

i having super hard time compiling , using taglib 1.6.3 in qt project. i've tried can think of. taglib claims supported through cmake i'm not having luck. furthermore, i'm confused kinds of files need qt libs! i've built *.a files, *.lib, , *.dll. understand far... believe since i'm working in windows *.lib want. no matter do, end "undefined references" taglib functions try use when try compile qt project. have tried mingw32, msys, visual studio 2008, , cross-compiling windows on linux. turning nothing. what makes less sense me if compile same taglib source qt on mac (g++ think?) works fine! somewhere in windows compilation procedures have going wrong. have been smacking face on desk 30 (on , off) hours trying figure out. since qt uses mingw must compile taglib same compiler? if compile *.lib's visual studio not compatible? are *.a libraries usable in windows? (assuming mingw) i'm still trying handle on c++ stuff, after reading coun...
