// Create client
SchemaServiceClient schemaServiceClient = await SchemaServiceClient.CreateAsync();
// Initialize request argument(s)
UpdateSchemaRequest request = new UpdateSchemaRequest
{
    Schema = new Schema(),
    AllowMissing = false,
};
// Make the request
Operation<Schema, UpdateSchemaMetadata> response = await schemaServiceClient.UpdateSchemaAsync(request);

// Poll until the returned long-running operation is complete
Operation<Schema, UpdateSchemaMetadata> completedResponse = await response.PollUntilCompletedAsync();
// Retrieve the operation result
Schema result = completedResponse.Result;

// Or get the name of the operation
string operationName = response.Name;
// This name can be stored, then the long-running operation retrieved later by name
Operation<Schema, UpdateSchemaMetadata> retrievedResponse = await schemaServiceClient.PollOnceUpdateSchemaAsync(operationName);
// Check if the retrieved long-running operation has completed
if (retrievedResponse.IsCompleted)
{
    // If it has completed, then access the result
    Schema retrievedResult = retrievedResponse.Result;
