Welcome to StackOverflow :D
There are 2 tools that should help you in dealing with it :
- XSD.EXE will generate a schema and classes that you can add to your project
- XSD2Code will generate classes from a schema as well as Serialize/Deserialize methods
Suggestion :
Use XSD.EXE to generate your schema then use XSD2Code to generate classes from that schema.
Both tools are free,
The first one you access it through the Developer Command Line :
xsd file.xml
The second one is a Visual Studio add-in : (tutorial on their site)
Do not forget to accept the answer if you are satisfied with it or ask for more details by editing your question.
