Hi I have been trying to solve my problem, however couldn't do anything about it.

The problem is

http://localhost/productservice/service.svc when type this address in my browser it gives me 503 Service Unavailable error

When I run my code from VS 2010 it gives me

The HTTP service located at http://localhost/ProductsService/Service.svc is too busy. exception.

ProductService is running in the ASP.NET v4.0 integrated application pool with the ApplicationPoolIdentity.

I just got no idea what I need to do!

(Windows 7 Home & IIS7)

basicHttpBinding is used

the server side config is

<?xml version="1.0"?>
<configuration>
    <connectionStrings>
        <add name="AdventureWorksEntities" connectionString="metadata=res://*/ProductsModel.csdl|res://*/ProductsModel.ssdl|res://*/ProductsModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=PINCHY\SQLEXPRESS;Initial Catalog=AdventureWorks;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient"/>

                    <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
                    <serviceMetadata httpGetEnabled="true"/>
                    <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
                    <serviceDebug includeExceptionDetailInFaults="false"/>
                </behavior>
            </serviceBehaviors>

    </system.serviceModel>
    <system.webServer>
        <modules runAllManagedModulesForAllRequests="true"/>

the client app.config is

                contract="ProductsService.IProductsService" name="BasicHttpBinding_IProductsService" />
        </client>

</configuration>

Any help will be much appreciated Thanks

Had the same problem, but a different cause. In IIS (left side panel), click on Application Pools and make sure the ASP.NET version you've selected is actually running. Mine was off for some reason.
