wish of those help Here is how (with milestone 5, but its similar for other versions). Cosmos does the VGA stuff for you. It also does the mouse and keyboard. I haven't been able to make a keyboard yet, but I have a working mouse (although I havent been able to find out how to see if buttons are down). Ill show you the VGA functions to get you started. First, you need this namespace:
code :


Share : facebook icon twitter icon

wish help you to fix your issue The problem is with your partitionKeyValue. You are providing the partition key definition instead of the value. The value is the actual tenant id not the text tenantId.
Your delete code should then look like this:
code :
private async Task DeleteFamilyItemAsync()
{
    var partitionKeyValue = "5c6cb2d77c1c2edc001b9007"; // <-- This is the change
    var orderId = "abae8abf-5836-464f-8129-1f0e83a1f639";

    // Delete an item. Note we must provide the partition key value and id of the item to delete
    ItemResponse<Order> orderResponse = await this.container.DeleteItemAsync<Order>(orderId, new PartitionKey(partitionKeyValue));
    Console.WriteLine("Deleted Family [{0},{1}]\n", partitionKeyValue, orderId);
}

may help you . The Cosmos DB emulator is running locally on your machine or in Docker.
This means that you should be able to either install the emulator as a service or pull the docker image and run it in your machine. The emulator won't call anything external while it's running so as long as you have the internet to download the installer or the image you will be able to connect to it.

To fix this issue In EF Core 3.0+ provider extension methods like Cosmos(), SqlServer() etc. as well as Relational() have been removed. Now they are provided as direct extension methods of the corresponding metadata interfaces, with all previous properties replaced with Get / Set extension methods.
In your case, the replacement of Cosmos().ContainerName property are GetContainer and SetContainer extension methods:
code :
metadata.SetContainer(dbSet.Name);

help you fix your problem Right now filtering the Change Feed by a query is not supported, like you said, you can filter by PartitionKeyRangeId and use the ContinuationToken to iterate over the feed.
Here is the UserVoice item that tracks this request with an alternative using Spark.
