Create Schema using Core Service

Question

I am learning how to use the Tridion 2011 Core Service API and am trying to create a new folder containing a new Person schema with a single Name field.

When I run the following code I get the error FaultException : Namespace URI must have a value. If I uncomment the personSchemaFields.Namespa... it works fine but I'm pretty sure that this isn't the correct solution as I get errors later on when trying to use the schema (cannot find uuid:[GUID]:Person).

using (var client = new Tridion2011CoreService.CoreServiceClient())
{
    var newFolder = client.GetDefaultData(ItemType.Folder, "tcm:4-160721-2");
    newFolder.Title = DateTime.Now.Ticks.ToString();
    newFolder = client.Create(newFolder, new ReadOptions());

    var personSchemaDataFields = new List<ItemFieldDefinitionData>();

    var personSchemaFieldName = new SingleLineTextFieldDefinitionData();
    personSchemaFieldName.Name = "Name";
    personSchemaFieldName.Description = "Name";
    personSchemaDataFields.Add(personSchemaFieldName);

    var personSchemaFields = new SchemaFieldsData();
    //personSchemaFields.NamespaceUri = "uuid:" + Guid.NewGuid().ToString();
    personSchemaFields.RootElementName = "Person";
    personSchemaFields.Fields = personSchemaDataFields.ToArray();

    var personSchema = (SchemaData)client.GetDefaultData(ItemType.Schema, newFolder.Id);
    personSchema.Title = "Person";
    personSchema.Description = "Person";
    personSchema.RootElementName = "Person";
    personSchema.Xsd = client.ConvertSchemaFieldsToXsd(personSchemaFields).ToString();
    // The next line generates the following error. "FaultException : Namespace URI must have a value."
    personSchema = (SchemaData)client.Create(personSchema, new ReadOptions());
}

Could anyone help?

Exception is correct. You should provide a NamespaceUri for the schema. The exception you get later on is telling you that you need to set Content property of your ComponentData that will match the schema. You can use GetInstanceData method to get default value of the Content XML
