.net - Assembly binding error - fusion log and dependency browser mismatch -

i'm chasing down assembly loading/binding error has popped recently. during investigation i've found confusing contradiction (assuming i'm parsing fusion log correctly).

the exception thrown application @ startup states:

{"could not load file or assembly 'microsoft.practices.compositeui, version=1.0.51205.0, culture=neutral, publickeytoken=31bf3856ad364e35' or 1 of dependencies. located assembly's manifest definition not match assembly reference. (exception hresult: 0x80131040)":"microsoft.practices.compositeui, version=1.0.51205.0, culture=neutral, publickeytoken=31bf3856ad364e35"}

some recent project changes made should not require named assembly "microsoft.practices.compositeui". after confirming solution projects indeed referencing unsigned assemblies fired dependency browser make sure wasn't missing anything. checked out , confirmed didn't have "old" references old assemblies. of course cleaned , rebuilt project well.

i researched further , fired fusion log viewer (fuslogvw.exe) , configured display binding errors. viewed log , found binding error. detail log confusion starts; lists "calling assembly" assembly has no bindings (that can determine) missing assembly. ah, it's hard explain. here log:

* assembly binder log entry (11/15/2010 @ 7:00:18 pm) *

the operation failed.

bind result: hr = 0x80131040. no description available.

now calling assembly "microsoft.practices.enterpriselibrary.common" not have listed (via dependency browser) dependencies "microsoft.practices.compositeui". not that, shouldn't have any.

the fusion log has stopped me in tracks, fusion log has led confusion! ;0)

hopefully supplied enough info wise expert clue me in on i'm missing.

i'm not sure if answer appropriate or additional comment, please excuse me if have chosen incorrectly. ;0)

the news after reboot (power loss actually) problem went away. don't know how or why solved it, meticulous in researching problem sure enough reboot made go away!

thanks jeffn825 sticking , offering assistance, voted of comments.
