i'm building silverlight mvvm app (using galasoft mvvm light template). app has usercontrols. have stumbeld across somthing seems namespace issue. namespaces defined in way: myapp.controls -> user controls myapp.view -> different pages of app (which use user controls) myapp -> namespace of main page (root namespace) this works ok long don't give of usercontrols x:name . x:name defined, build breaks following message: error cs0426: type name 'controls' not exist in type 'myapp.myapp' that realy strange! can resolve issue changing namespace myapp.controls myappcontrols or manipulating generated code, direct reference myapp.controls.mycontrol replaced using myapp.controls , instanciate control mycontrol (however overwritten again, switch desgin view). does know reason strange behaviour? have expected common problem? i think found reason: had resource file name myapp. led generation of class myapp , therefore compiler got confu...

it's known silverlight lacks compelling x:type markupextension (markupextension is not supported in silverlight @ all). there dynamic workaround it? what enums ( x:static )? my need have commandparameter set type or enum value, neither of these supported in silverlight! this has done in code-behind. if build custom object exposes property of type type, not "converted" when set via xaml. this limitation prevents creating things custom enumvalueprovider, exposes type property , updates values properties enum values specified enumeration type. having class allow bind combobox or listbox list of enumeration values in xaml. you can create custom typeconverter above type property, work around issue. don't xmlns resolution you'd expect. depending on situation, may enough. here another example , exposes "known" types via properties, can bind to.

i have written thread in application. when thread starts running, ui screen becomes blank. how can avoid this? public class settickertext extends thread { @override public void run() { while(true) { systemclock.sleep(25000); log.i("map", "after wait"); } } it's going (don't have compiler near me): new settickertext().start() essentially, when tell thread object start, spins new thread, invokes run you. you're doing calling run ui thread, other function, it's blocking ui thread returning
