.net - Assembly loader confusing behaviour -
i developing vs2012 package (using sdk), implements custom visual designer. solution contains several projects. when run package in vs experimental instance, try open custom visual designer, following exception:
system.io.filenotfoundexception unhandled user code hresult=-2147024894 message=could not load file or assembly 'visualdesigner.configuration, version=0.0.0.0, culture=neutral, publickeytoken=c2639211081ade27' or 1 of dependencies. system cannot find file specified. source=system.configuration filename=visualdesigner.configuration, version=0.0.0.0, culture=neutral, publickeytoken=c2639211081ade27 (...) stacktrace: @ system.configuration.typeutil.gettypeimpl(string typestring, boolean throwonerror) @ system.configuration.typeutil.createinstancerestricted[t](type callingtype, string typestring) @ system.configuration.configurationproperty..ctor(propertyinfo info) @ system.configuration.configurationelement.createconfigurationpropertyfromattributes(propertyinfo propertyinformation) @ system.configuration.configurationelement.createpropertybagfromtype(type type) @ system.configuration.configurationelement.propertiesfromtype(type type, configurationpropertycollection& result) @ system.configuration.configurationelement.createconfigurationpropertyfromattributes(propertyinfo propertyinformation) @ system.configuration.configurationelement.createpropertybagfromtype(type type) @ system.configuration.configurationelement.propertiesfromtype(type type, configurationpropertycollection& result) @ system.configuration.configurationelement.get_properties() @ system.configuration.configurationelement.set_item(string propertyname, object value) @ visualdesigner.configuration.xmlconfiguration.element.flowsection.set_xmlns(string value) in c:\users\wjarema\repositories\visualdesigner\src\configuration\xmlconfiguration\element\flowsection.cs:line 20 it looks assembly binding problem, decided consult fusion log viewer additional info assembly loader error.
what strange, fusion log says when try open visual designer, there four attempts load visualdesigner.configuration - two times successfully, failed twice:

visualdesigner.configuration at first loaded successfully, thereafter loading of assembly causes failures?
i wonder why there stated in logs calling assembly : (unknown). in case of assembly binding failures?
