  1. OData 4.0 aggregation says:

    Is there any plan to provide support for aggregation ($apply and $groupby) ?

  2. AdamCaviness says:

    I have a question, you invite us to reach out to you, how does one go about doing that? For example, the Web API OData team ispart of the aspnetwebstack team (by inference); they are on CodePlex and I can create an issue in their issue tracking system but for your team I'm lost of how to reach out.  Are comments on this blog the only avenue?

    Still no support for Windows phone 8.1 🙁

    "ODataLib now supports new aysnc API in .Net 4.0"

    async API is in .Net 4.5

  5. @OData 4.0 aggregation

    The aggregation support is in our plan targeting later this year.

  6. @OnurG

    The support for Windows Phone 8.1 will be released together with ODataLib 6.5.0 in this month.

  7. @Scott_Xu

    Thank you for your feedback. What we actually mean is that the async APIs we added returns Task, which was firstly introduced in .NET 4.0, but they are not decorated with the "async" keyword, which was introduced in .NET 4.5. Thus, .NET 4.5 users can use these APIs together with the "async" and "await" keywords in their codes while users staying on .NET 4.0 can also use them in the .NET 4.0 fashion and compile on 4.0.

  8. @AdamCaviness

    You can contact us at odatafeedback@microsoft.com. I'll update all the posts that have "call to action" section with this mail address.

  9. Uffe says:

    I can't seem to find the BypassValidation property on the reader and writer settings.

  10. LeoHu1 says:

    aggregation will come late this year.

  11. Nicolas Lips says:

    For server-side aggregation you can use the LINQ extension .QueryByCube() provided by the component AdaptiveLINQ (www.adaptivelinq.com).

  12. Why not merge individual commits? says:

    Why do you folks dump the whole release in just one commit? Very hard to see what individual commits have gone into the release.

    Could you please start pushing all the commits when you sync the public repo with your private one?
