Hello World

A minimal end-to-end sample showing the basic task submission workflow with ArmoniK’s native C# API.

What it does

The client creates a session, uploads the string "Hello" as a payload, submits one task, waits for its result, then prints the returned string.

The worker reads the payload string and appends " World_ <resultId>" to it, then sends that as the task result.

Key concepts

Creating a session with SessionsClient
Uploading payload data inline with ResultsClient.CreateResults
Reserving a result slot with ResultsClient.CreateResultsMetaData
Submitting a task via TasksClient.SubmitTasks
Waiting for results with EventsClient.WaitForResultsAsync
Downloading result bytes with ResultsClient.DownloadResultData
Implementing a worker by overriding WorkerStreamWrapper.Process

Running

Client

dotnet run --project Client -- \
  --endpoint http://localhost:5001 \
  --partition default

Option	Default	Description
`--endpoint`	`http://localhost:5001`	ArmoniK control plane URL
`--partition`	`default`	Partition to submit tasks to

Worker

dotnet run --project Worker

The worker reads its gRPC endpoint from environment variables (standard ArmoniK worker configuration).
