Make Entity Framework save the dynamic proxy assembly it uses

SaveEntityFrameworkProxyAssembly.cs

        private void SaveEntityFrameworkProxyAssembly(params Type[] types)
        {
            var factoryType = typeof(ObjectContext).Assembly.GetType(
                "System.Data.Objects.Internal.EntityProxyFactory",

                = BindingFlags.Static
                | BindingFlags.NonPublic;

            factoryType
                .GetField("s_ProxyAssemblyBuilderAccess", privateStaticFlags)
                .SetValue(null, AssemblyBuilderAccess.RunAndSave);

            (new MyAppsDbContext() as IObjectContextAdapter)
                .ObjectContext
                .CreateProxyTypes(types);

            var moduleBuilders = (IDictionary<Assembly, ModuleBuilder>)
                factoryType
                    .GetField("s_ModuleBuilders", privateStaticFlags)
                    .GetValue(null);

            var proxyAssembly = (AssemblyBuilder)
                moduleBuilders[typeof(UserProfile).Assembly].Assembly;

            proxyAssembly.Save("EntityProxyModule.dll");
        }
