    copied!<p>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 <a href="http://blogs.msdn.com/alexj/archive/2010/03/02/creating-a-data-service-provider-part-9-un-typed.aspx" rel="nofollow noreferrer">http://blogs.msdn.com/alexj/archive/2010/03/02/creating-a-data-service-provider-part-9-un-typed.aspx</a></p> <p>I have written our own IDataServiceMetadataProvider / IDataServiceQueryProvider pair and get no errors on what i do.</p> <p>I am putting in a resource set like this:</p> <pre><code>ResourceType tableType = new ResourceType( typeof(Dictionary&lt;string, object&gt;), 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)); </code></pre> <p>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.</p> <p>Still, the output I get is:</p> <pre><code> &lt;?xml version="1.0" encoding="utf-8" standalone="yes" ?&gt; - &lt;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"&gt; - &lt;workspace&gt; &lt;atom:title&gt;Default&lt;/atom:title&gt; &lt;/workspace&gt; &lt;/service&gt; </code></pre> <p>And for the $metadata version:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8" standalone="yes" ?&gt; - &lt;edmx:Edmx Version="1.0" xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx"&gt; - &lt;edmx:DataServices xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" m:DataServiceVersion="1.0"&gt; - &lt;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"&gt; &lt;EntityContainer Name="Martini" m:IsDefaultEntityContainer="true" /&gt; &lt;/Schema&gt; &lt;/edmx:DataServices&gt; &lt;/edmx:Edmx&gt; </code></pre> <p>The actual metadata for the types never shows up, no error is shown. pretty frustrating. Anyone any idea?</p>
