As per my requirement whenever I am calling ODATA V4 controller get request, from ajax I don't want to get Odata.Etag from response.
How can we achieve this. Is there any Web Api Odata server side configuration to disable Etags?
"@odata.context": "http://localhost:56274/odata/$metadata#Controller",
"@odata.count": 1,
"value": [{
"@odata.etag": "W/\"YmluYXJ5J0FBQUFBRnFFUUE4PSc=\"",Thursday, February 15, 2018 5:20 PM

Hi evurihanumantharao,
How can we achieve this. Is there any Web Api Odata server side configuration to disable Etags?As far as I know, if don't enable the [TimeStamp] attribute or the [ConcurrencyCheck]attribute in your data model.
It will not add the etag in the response.
So I suggest you could recheck your model to make sure you don't add the attribute.
Here I also create an example with etag in odata v4.
The data model.
public class Person { [Key] public int Id { get; set; } [Required] public string Name { get; set; } [Required] [Timestamp] public int Age { get; set; } }
Result:
If I remove the "[Timestamp]" or " [ConcurrencyCheck]", it will not generate the etag.
Best Regards,
Brando

Thanks for your response.
If I change the TimeStamp/ConcurrencyCheck that will impact on my entity framework behavior. I am looking for the option which can work at Odata Level. I need to eliminate this tag from Odata responses.

Hi,
Either use either the [TimeStamp] attribute or the [ConcurrencyCheck] attribute but not both.
See the "Support for ETags" section in this MSDN blog post.

For anyone else stumbling across this post, we found that adding an [IgnoreDataMember] attribute to the property solves this (unless you absolutely need the property with the Timestamp attribute in your response)
