Azure-docs: How to set Container Default TTL on Extisting Container with dotnet v3 SDK ?

[xtellurian]

The docs here describe how to set the default TTL when creating a container via the dotnet SDK (v3).

However I can't find any documentation on how to change the default TTL after the collection has been created. I cant find a DefaultTimeToLive property or a ContainerProperties property on the C# objects.

I expected to be able to do something like this:

var options = new MyCosmosOptions();
var client = new CosmosClient(options.Endpoint, options.PrimaryKey);
var container = client.GetContainer(options.Database, containerName);
container.SetDefaultTimeToLive(60); // no method like this exists afaik

@xtellurian We are checking this and will get back to you.

@xtellurian Please try the below snippet to enable TTL on an existing container.

```cs

var containerResponse = await simpleContainer.ReadContainerAsync();

ContainerProperties containerProperties = containerResponse;

containerProperties.DefaultTimeToLive = (int)TimeSpan.FromDays(1).TotalSeconds; //expire in 1 day

var containerResponseWithTTLEnabled = simpleContainer.ReplaceContainerAsync(containerProperties);

`

@KalyanChanumolu-MSFT that appears to work, thanks :)

This could be a useful thing to include in the docs.

@xtellurian Thank you for the suggestion.
Let me see if I can add it to the documentation. If not I will add it to the Code Samples here
