Moving To “Indigo”Moving To “Indigo”

“Indigo” works well with COM+, MSMQ, WSE, and ASMX apps“Indigo” nodes are easy to integrate into existing systemsExisting applications have an easy migration path to “Indigo”

Existing serializable types and serialization extensibility points just work

Follow the prescriptive guidance for writing distributed applications

Read and follow the serializable type guidelines
