IDataServiceMetadataProvider - Entities dont show up in $metadata.
- by TomTom
I am trying to write our own RIA services provider to expose data from a server that I access via ODBC. I follow th eguidelines set out at http://blogs.msdn.com/alexj/archive/2010/03/02/creating-a-data-service-provider-part-9-un-typed.aspx
I have written our own IDataServiceMetadataProvider / IDataServiceQueryProvider pair and get no errors on what i do.
I am putting in a resource set like this:
ResourceType tableType = new ResourceType(
typeof(Dictionary<string, object>),
ResourceTypeKind.EntityType,
null,
"Martini",
table_name,
false
);
tableType.CanReflectOnInstanceType = false;
var prodKey = new ResourceProperty(
"Key",
ResourcePropertyKind.Key |
ResourcePropertyKind.Primitive,
ResourceType.GetPrimitiveResourceType(typeof(int))
);
prodKey.CanReflectOnInstanceTypeProperty = false;
tableType.AddProperty(prodKey);
var prodName = new ResourceProperty(
"Name",
ResourcePropertyKind.Primitive,
ResourceType.GetPrimitiveResourceType(typeof(string))
);
prodName.CanReflectOnInstanceTypeProperty = false;
tableType.AddProperty(prodName);
_MetaDataProvider.AddResourceType(tableType);
_MetaDataProvider.AddResourceSet(new ResourceSet(table_name, tableType));
I see the requests coming in for enumerating the resource sets. I check them there in a breakpoint, and the resource set and the type is there, with all properties.
Still, the output I get is:
<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
- <service xml:base="http://localhost:2377/MartiniData.svc/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:app="http://www.w3.org/2007/app" xmlns="http://www.w3.org/2007/app">
- <workspace>
<atom:title>Default</atom:title>
</workspace>
</service>
And for the $metadata version:
<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
- <edmx:Edmx Version="1.0" xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx">
- <edmx:DataServices xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" m:DataServiceVersion="1.0">
- <Schema Namespace="Martini" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://schemas.microsoft.com/ado/2007/05/edm">
<EntityContainer Name="Martini" m:IsDefaultEntityContainer="true" />
</Schema>
</edmx:DataServices>
</edmx:Edmx>
The actual metadata for the types never shows up, no error is shown. pretty frustrating. Anyone any idea?
