extendedProtectionPolicy tag problem: Workaround

When one use Windows7 to generate a WCF configuration file/ proxy that will generate some extra lines of code which will cause the problems in running the application.
The extra lines generated are not supported in Silverlight/WPF environment.
Those lines will look like
<transport>
    <extendedprotectionpolicy policyenforcement="Never" />
</transport>
There are some limitations for silverlight & WPF to use custombinding. You can read an article related to this at

Solution Array for List in WCF

Here is another common problem encounters with WCF Service in initial days. Suppose there is a method which returns a List of Objects the proxy will be generated as method which returns an array of objects. Reason: This problem is due to the default interpretation of collections. While generating proxy for the service all the collections are by default interpreted as arrays. That is why all the lists will be converted to arrays. Solution: If you are generating proxy by adding service reference from visual studio directly, there will be a 'advanced' button. Click that button and select the System.Generic.List as your Collection. This will resolve the problem. If you are generating proxy with svcutil here is the command to do the job. svcutil.exe http://ServerName/ServiceName/Servic.svc?wsdl /collectionType:System.Collections.Generic.List`1 or in short svcutil http://ServerName/ServiceName/Servic.svc?wsdl /ct:System.Collections.Generic.List`1 for more information go through this ...

Linq: Query for multiple join conditions in Linq to SQL

This is common to join a table with another on multiple conditions, Like Select * from Customer c Join Invoice i on c.CustomerID = i.CustomerID and c.CustomerTypeID = i.CustomerTypeID I need to write a Linq to SQL query for the same scenario. But the syntax for this query is a bit different to expect. The Linq query is as follows: From c in DataContext .Customers Join i in DataContext .Invoices on new { c.CustomerID, c.CustomerTypeID } equals new { i.CustomerID, i.CustomerTypeID } *DataContext in the above query should be replaced with actual datacontext name.

Troubleshoot WCF service returning object with null fields

When you are working with WCF service for the first time, generally you will get this error for some reason. Here is the description of the error: WebServiceReference . ServiceClient client = new WebServiceReference . ServiceClient (); WebServiceReference . ImplementationRequest req = new WebServiceReference . ImplementationRequest (); req = client.GetRequest(); Here the Method GetRequest will return an object of ImplementationRequest. Everything will run without any error but the req object will contain all null fields/ majority null fields. Solution: Those nulls are due to error in generating the proxy for the Data Contract defined by the service. Verify that [DataMember] attribute tag is given for all the data fields and [DataContract] for the Class. If those attributes are missing, the object will be generated with null values. If all fields have the tags but the issue is not resolved, then the service reference should be re-added and the proxy should be re-generated. Then t...
