Interfaces Lack Data

Why does having two known types blow up for being conflicting data contract types if the types are two different interfaces? An interface only contains declarations for its members. The interface doesn't contain any data fields and any implementation

Building a Data Contract Serializer Behavior

In configuration there's a DataContractSerializer behavior that I can add to my service, but the class it uses is internal. How do I get the same behavior programmatically? The DataContractSerializer behavior is a shortcut for setting the MaxItemsInObjectGraph

Collection Name Generation

Last time we were looking at how to replace the default names used for serializing collections , such as ArrayOfKeyValueOfstringArrayOfstringty7Ep6D1, with more intelligible names. However, where did that funny looking name come from in the first place?

Types of Collections

If a type implements multiple kinds of collections, which pattern for collection types will be used when the object is serialized? The order that is checked for supporting collection interfaces is: IDictionary<TKey, TValue> IDictionary IList<T>

Fault Serialization with XmlSerializer

About 20 posts ago, back before PDC, this was the next topic in the queue to be posted. It has been somewhat delayed by all of the talk of product announcements and details about future releases. Since it was becoming lonely and forgotten I thought I'd

No Choice for Data Contracts

I have a schema file that describes a choice between multiple layout formats for a type. How do I build a proxy that matches this schema? The reason that this is probably not working is because DataContractSerializer for the most part does not support

Getting Better Time Formats

Orcas introduced a new DateTimeOffset class that is easier to use for representing absolute times than the original DateTime class. However, if you run svcutil on a contract that contains a DateTimeOffset, you'll get an ugly generated structure because

I was working on some services with recursive data structures when I noticed that there were a few cases where I would get crashes while trying to generate proxy classes. The problems seemed to be around types that were a sequence of instances of themselves.
