RavenDB Embedded on Azure Websites - Access Denied

Question

I get an Access denied message when I try to deploy my MVC4 site with an Embedded instance of RavenDB to the new Azure Websites preview feature. The site works fine locally.

Here is how I configure Raven:

//Initialize the RavenDB Data Store
        Raven.Database.Server.NonAdminHttp.EnsureCanListenToWhenInNonAdminContext(8887);

        var documentStore = new EmbeddableDocumentStore()
        {
            DataDirectory = "~\\App_Data",
            UseEmbeddedHttpServer = true, 
            Configuration = { Port = 8887 }
        };

        documentStore.Initialize();

And here is the stack trace when I browse to the site:

Access is denied

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.Net.NetworkInformation.NetworkInformationException: Access is denied

I managed to get it to work, although it is not ideal. You may notice in my original post that I am setting the UseEmbeddedHttpServer = true. This is so that I can browse to http:[MyUrl]:8081 and get the RavendDB Management Studio so that I can browse my data. For some reason, RavenDB wants to do the same kind of port check when this property is set as it does when you set the Port setting to automatic (Port=*).

I believe that RavenDB may need a fix so that it honors the Port setting when UseEmbeddedHttpServer is True and also let you set the Configuration property of the EmbeddedDocumentStore upon creation.

But in the meantime, you can truly get your MVC4 site to work with an EmbeddedDocumentStore on Azure Websites simply by specifying a port. Also, you do indeed have to use the AppSettings configuration rather than setting the Configuration property of the EmbeddedDocumentStore upon creation (like I tried to do above). This post (stackoverflow.com/questions/11529159/) shows how to do it.

Unfortunately, I still haven't found a way to run the EmbeddedHttpServer so I can use the Raven Management Studio. If I figure out how, I will post a solution here.

Hi this was answered on RavenDb on Azure Websites - Access Denied Basically you need to configure the port in Web.config
