Do you have any suggestions for where I should be looking to troubleshoot this error? 

I have two model project pairs and two modules.  The 6.1.5 model projects and module work just fine (with the 6.1.6 dll's).  The 6.1.6 model projects and module complain about the metadata.

Any help would be appreciated. 

Thanks,

Simon

 

Also, I am attaching some source code for the projects that work and that don't.  Open the ClassLibrary1.sln to load all 6 projects.  The EdiTransactions work, the MeasurementPPAs don't.

uploads/308/ClassLibrary1.zip - uploads/308/ClassLibrary1.zip

 

We will take a look at it.

We have a ton of modules and models that all use the same connection string.  So we have a CustomDataSourceKeyResolver that auto-resolves the DataSourceKey if the DataSourceKey property is set to the exact name of the .edmx file.

 

class CustomDataSourceKeyResolver : IDataSourceKeyResolver 
    {
        public IDataSourceKey GetKey(string keyName, string keyExtension, bool onServer)
        {
            if (!onServer) return null;
            try
            {
                string site = "/Ag";
#if DEBUG
                site = "/ExperimentWeb";  //When ran locally this is the site name
#endif
                System.Configuration.Configuration rootWebConfig =
                    System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration(site);
 
                System.Configuration.ConnectionStringSettings connString;
                string conKey = "TheOneKey";
                if (rootWebConfig.ConnectionStrings.ConnectionStrings.Count > 0)
                {
                    conKey = string.IsNullOrEmpty(keyExtension) ? conKey : keyExtension;
                    connString = rootWebConfig.ConnectionStrings.ConnectionStrings[conKey];
                    if (connString == null) return null;
                }
                else
                {
                    return null;
                }
 
                bool trace = keyName != "CommonModel";
                string name = string.IsNullOrEmpty(keyExtension) ? keyName : keyName + "_" + keyExtension;
                string connectionString =
                    string.Format(
                        "metadata=res://*/{0}.csdl|res://*/{0}.ssdl|res://*/{0}.msl;provider={2};provider connection string='{1}'",
                        keyName, connString.ConnectionString, connString.ProviderName);
                return new ClientEdmKey(name, connectionString, trace, "FromResolver");
            } catch
            {
                throw new Exception("Unable to find connection information.");
            }
        }
    }

 

I was looking at your projects, but was having trouble as it has references to non-included assemblies and doesn't compile.
