Impossible de charger le fichier ou l'assembly 'DocumentDB.Spatial.Sql.dll' ou une de ses dépendances

Question

Nous avons 3 projets:

• Class Library (Framework cible 4.5)
• Web App (MVC) Project (Framework 4.5 cible)
• API Web Project (Framework cible 4.5.2)

récemment commencé à travailler avec Azure (pilote document DB) Cosmos DB. Toute l'implémentation est effectuée dans la bibliothèque de classes utilisée dans les projets API Web &.

Apparemment, Web App fonctionne très bien, mais projet REST api renvoie une erreur:

Could not load file or assembly 'file:///API\bin\DocumentDB.Spatial.Sql.dll' or one of its dependencies. The module was expected to contain an assembly manifest. 
 

 
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 
 

 
Exception Details: System.BadImageFormatException: Could not load file or assembly 'file:///D:\API\bin\DocumentDB.Spatial.Sql.dll' or one of its dependencies. The module was expected to contain an assembly manifest. 
 

 
Source Error: 
 

 
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. 
 

 
Assembly Load Trace: The following information can be helpful to determine why the assembly 'file:///D:\API\bin\DocumentDB.Spatial.Sql.dll' could not be loaded. 
 

 

 
WRN: Assembly binding logging is turned OFF. 
 
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. 
 
Note: There is some performance penalty associated with assembly bind failure logging. 
 
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Maintenant, ont essayé les correctifs suivants (sans succès):

1. Modifié l'API Target Framework à 4.5, redémarré - toujours la même erreur.
2. Nettoyer la solution, reconstruire - toujours la même erreur
3. La DLL DocumentDb.Spatial.Sql.dll est identique dans le projet Web Web & Web API.

Answer 1

Could not load file or assembly 'file:///API\bin\DocumentDB.Spatial.Sql.dll'

Ce chemin est suspect. Vous devez vérifier quel module essaie de charger cette DLL (et pourquoi)

Essayez d'activer la journalisation des liaisons d'assemblage et vérifiez les erreurs pendant le chargement de la solution. Pour activer la journalisation coller ce au fichier txt (et l'extension de changement à .reg):

Windows Registry Editor Version 5.00 

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion] 
"ForceLog"=dword:00000001 
"LogFailures"=dword:00000001 
"LogResourceBinds"=dword:00000001 
"LogPath"="C:\\FusionLog" 

Après cela, vérifiez le dossier C: \ FusionLog et rechercher ce DocumentDB.Spatial.Sql.dll dll)
