BWF gooi Filenotfound uitsondering vir "System.ServiceModel" wanneer die skep van ServiceHost

Question

Ek hardloop in 'n baie vreemde probleem met WCF. Ek het 2 projekte in 'n oplossing, elkeen van hulle begin 'n paar self-hosted WCF dienste.

Projek 1:

myService = new ServiceHost(typeof(MyService1));

Watter loop fyn. Maar wanneer ek probeer om my 2de projek, wat bevat loop:

meService = new ServiceHost(typeof(MyOtherService));

Ek kry die uitsondering:

FileNotFoundException
Could not load file or assembly 'System.ServiceModel' or one of its dependencies.
The system cannot find the file specified.":"System.ServiceModel

Die werklik vreemd deel is dat in die debugger, teen die tyd dat ek hierdie uitsondering, ek kan in 'QuickWatch' gaan in Visual Studio en betree:

new MyOtherService()  // returns new instance properly
new ServiceHost()     // returns new instance properly
new ServiceHost(typeof(MyOtherService))  // throws exception, same as above.

Ek het probeer hardloop Sysinternals File System Watcher terwyl ontfouting, maar dit toon geen 'filenotfound' behalwe devenv.exe probeer opspoor Pdb lêers na die stapel spoor genereer foute.

Enigiemand enige ander idees van wat om te kyk na?

Update # 1

Ek bewys nie die samesmelting log vir die proses, en dit lyk iets vreemds gebeur. Daar is 2 log inskrywings vir System.ServiceModel, rug aan rug:

Toe 'n 2de inskrywing:

So dit blyk dat dit probeer om System.ServiceModel twee keer te laai, en een keer uit die plaaslike jeug rig in plaas van die GAC? Ek is verward ...

Answer 1

Resultate my probleem:

Vir beide projekte (kan noem hulle MyProj1 en MyProj2) Ek het hierdie lyn in die .dll.config lêer:

<serviceAuthorization principalPermissionMode="Custom" serviceAuthorizationManagerType="System.ServiceModel.ServiceAuthorizationManager, System.ServiceModel" />

Proj1 loop fyn, Proj2 versuim met die uitsondering hierbo. Vir een of ander rede in Proj2 net, dit lyk net in my private gids \ bin wanneer ek probeer om op te los "System.ServiceModel".

As ek verander die bo lyn om die volle vergadering naam het:

<serviceAuthorization principalPermissionMode="Custom" serviceAuthorizationManagerType="System.ServiceModel.ServiceAuthorizationManager, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

Alles werk weer. Hoe vreemd ... ek het geen idee hoekom presies dieselfde config naslaanwerke vir 'n projek en nie 'n ander, maar hey ... ten minste wat ek kan terug te kry om nou te werk:)

Answer 2

paar vrae:

• Doen beide van jou projekte te rig ten minste NET Framework 3.0 of hoër?
• kan jy wys vir ons die koppelvlakke wat die twee dienste te implementeer, en die rowwe uiteensetting van die diens implementering klasse hulself?

Answer 3

Ek sal probeer verwyder en weer die toevoeging van die verwysing in die tweede projek om die System.ServiceModel vergadering. Miskien 'n ander dev het hy bygevoeg met behulp van 'n plaaslike lêer in plaas van die GAC weergawe wat kwessies op jou plaaslike omgewing veroorsaak?
