"The type or namespace name `Packages' could not be found" when consuming OData feed

Question

I want to test the following simple example but getting the highlighted error. I have the following namespace using Simple.OData.Client

Answer 1

It seems you've copied code from either here or here, where it is stated that both are examples, not working code.

In order to deserialize a feed into a class, that class must exist. The OData client library you use has no connection whatsoever to NuGet, it just uses its feed as an example.

At the latter link it is also mentioned:

Simple.OData.Client doesn't generate proxy classes but you should be able to easily add classes for entities you plan to use by navigating to the OData feed and inspecting its metadata. Use URL $metadata to obtain metadata description. If you have Visual Studio you can create a proxy by creating a project and adding service reference to it. Then you can use the generated classes.

From the URL http://www.nuget.org/api/v1/$metadata you should be able to create a Service Reference (of which you will not use the proxy) that will generate the V1FeedPackage type, which you can then use:

var packages = await client
    .For<V1FeedPackage>()
    .Filter(x => x.Title == "Simple.OData.Client")
    .FindEntriesAsync();

foreach (var package in packages)
{
    Console.WriteLine(package.Title);
}
