Errore di ServiceStack Caricamento di WebHost Endpoint

Question

Sto cercando di seguire l'esempio Hello di ServiceStack. Sto utilizzando Visual Studio 2010, Win 7 a 64 bit, ma IIS è configurato per l'esecuzione di applicazioni a 32 bit. Il progetto Hello che ho creato utilizza ASP.Net MVC3. Ottengo questo errore nel tentativo di accedere ai metadati:

Could not load type 'ServiceStack.WebHost.Endpoints.AppHostBase' from assembly 'ServiceStack, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' 

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.

Answer 1

Ho incontrato lo stesso problema - quando ho creato il progetto ASP.NET vuoto ho chiamato - giustamente abbastanza - ServiceStack. (Problema di attivazione) Quando aggiornavo il mio nome di progetto ASP (e tutti i Namespace corrispondenti) in qualcosa di analogo a ServiceStackExperiment - tutto era unicorni e arcobaleni.

Questo è un post molto vecchio, ma questo potrebbe aiutare qualcuno se hanno ricevuto un errore simile quando si sviluppano contro versione ServiceStack 4.

Ci sono state alcune modifiche richieste per il file web.config se avete deciso di copiare e incolla da alcune guide servicestack che sono stati scritti per la versione serviceStack 3.

Http sezioni gestore che ha lo spazio dei nomi ServiceStack.Webhost dovranno essere modificati per qualcosa come il seguente

<httpHandlers> 
    <add path="*" type="ServiceStack.HttpHandlerFactory, ServiceStack" verb="*"/> 
    </httpHandlers> 

    <handlers> 
    <add path="*" name="ServiceStack.Factory" type="ServiceStack.HttpHandlerFactory, ServiceStack" verb="*" preCondition="integratedMode" resourceType="Unspecified" allowPathInfo="true" />   
    </handlers> 

Spero che aiuti qualcuno!
