entity framework 4 - Visual Studio 2010 Windows Forms Designer Problems -

isn't crazy error?

i when trying open form containing usercontrols assebly , using entity framework , sql ce on visual studio designer.

object of type namespace.t[] cannot converted type namespace.t[]!!!

call stack:

but same name type exactly!

the project builds , runs ok!!!

ok deleted .resx file of form , 2 other errors thought have passed.

1st "the specified named connection, not intended used entityclient provider, or not valid"

call stack:

at system.data.entityclient.entityconnection.changeconnectionstring(string newconnectionstring) @ system.data.entityclient.entityconnection..ctor(string connectionstring) @ system.data.objects.objectcontext.createentityconnection(string connectionstring) @ system.data.objects.objectcontext..ctor(string connectionstring, string defaultcontainername) @ djpro.settings.model.settingsentities..ctor() in d:\visual studio projects\djproautomation\djpro.settings.model\settingsselftrackmodel.context.cs:line 33 @ djpro.data.access.settingsdataoperations.getconfiguration() in d:\visual studio projects\djproautomation\djpro.data.access\settingsdataoperations.cs:line 33 @ djpro.studio.controls.deckcontrol..ctor() in d:\visual studio projects\djproautomation\djpro.deck.controls\deckcontrol.cs:line 51

2nd control have on library saying.

"the variable deckcontrol1 either undeclared or never assigned"

call stack:

at system.componentmodel.design.serialization.codedomserializerbase.error(idesignerserializationmanager manager, string exceptiontext, string helplink) @ system.componentmodel.design.serialization.codedomserializerbase.deserializeexpression(idesignerserializationmanager manager, string name, codeexpression expression) @ system.componentmodel.design.serialization.codedomserializerbase.deserializeexpression(idesignerserializationmanager manager, string name, codeexpression expression) @ system.componentmodel.design.serialization.codedomserializerbase.deserializestatement(idesignerserializationmanager manager, codestatement statement)

then restored backup resx file , im going first problem.

so strange errors, seems fine in entity data model libraries , app.config has necessary connection strings. deckcontrol1 usercontrol seems fine library have created , opens ok.

i think gets me crazy enough , stops development.

any idea?

it looks have version conflict between assembly used generate resx , referenced assembly.

try removing reference, re-adding project reference, , regenerating resx.
