How do I run an Azure DevOps pipeline using the Azure DevOps NuGet and at the same time specify resources?

I'm building upon the question asked in "How do I queue a build and only run specific stages with the azure devops nuget?", but I have a need for extending it further, to specify some resources.

In my pipeline YAML, I have defined a "pipeline" resource, that is ultimately used to download a build artifact.

I can use the same PipelinesHttpClient mentioned in the referenced question to retrieve a pipeline run that was performed manually (note: important to use the client from the "Microsoft.Azure.Pipelines.WebApi" namespace, rather than the one in the older "Microsoft.TeamFoundation.Pipelines.WebApi" namespace).

Through that instance I see that it has a Resources property that further has a Repositories property, with an item named "self", containing an instance of "Microsoft.Azure.Pipelines.WebApi.RepositoryResource".

The problem comes when trying to replicate this instance in code. I ultimately get stuck on trying to instantiate a RunResourcesParameters instance I need for assigning to a RunPipelineParameters instance's Resources property.

If I just instantiate a "vanilla" RunPipelineParameters instance, I end up with its Resources property being null:

I see that its type is RunResourcesParameters, so tried instantiating that. However, it won't let me do that, due to its protection level:

var runResourcesParameters = new RunResourcesParameters();

It has an other ctor as well, but the same goes for that:

var runResourcesParameters2 = new RunResourcesParameters((ISecuredObject)(new object()));

It's defined like this: and further like this:

The same problem of course occurs if I try object initialization on the RunPipelineParameters instance:

var runParameters = new RunPipelineParameters{Resources = };

var runParameters = new RunPipelineParameters{Resources = new RunResourcesParameters()};

What am I doing wrong?

I've looked at the ".NET client samples", but it doesn't contain anything for PipelinesHttpClient. I note that the repo has been set in read-only mode back in 2021.

The NuGet page for the "Microsoft.TeamFoundationServer.Client" NuGet package shows that there is a brand new 19.x series package in preview these days, so possibly the samples will be revived in combination with that?

To solve this issue, we can use the following code:

    string json = @"{ 'Builds': {}, 'Containers': {}, 'Repositories': {}, 'Pipelines': {}, 'Packages': {} }";
    RunResourcesParameters test = JsonConvert.DeserializeObject<RunResourcesParameters>(json);

    test.Pipelines.Add(name, PipelineResource);

    parameters.Resources = test;

Full code sample:

using System;

using System.IO;

using System.Runtime.Serialization;

using Microsoft.Azure.Pipelines.WebApi;

using Microsoft.TeamFoundation.Build.WebApi;

using Microsoft.TeamFoundation.Core.WebApi;

using Microsoft.TeamFoundation.SourceControl.WebApi;

using Microsoft.VisualStudio.Services.Common;

using Microsoft.VisualStudio.Services.WebApi;

using Newtonsoft.Json;

using Newtonsoft.Json.Linq;
namespace ConsoleApp5

{

    class Program

    {


        static async Task Main(string[] args)

        {


            var vssConnection = new VssConnection(new Uri("https://dev.azure.com/orgname"), new VssBasicCredential(string.Empty, "PAT"));

            var name = "pipelineresourcename";

            var pipelineClient = new PipelinesHttpClient(vssConnection.Uri, vssConnection.Credentials);

            var PipelineResource = new PipelineResourceParameters();

      
            PipelineResource.Version = "Pipelineresourceversion";

            var parameters = new RunPipelineParameters();



 

            string json = @"{ 'Builds': {}, 'Containers': {}, 'Repositories': {}, 'Pipelines': {}, 'Packages': {} }";
            RunResourcesParameters test = JsonConvert.DeserializeObject<RunResourcesParameters>(json);

            test.Pipelines.Add(name, PipelineResource);

            parameters.Resources = test;



           

            var run = await pipelineClient.RunPipelineAsync(parameters, "projectid", pipelineid);

        }

    }

}

When you run the c# sample, the pipeline resource info will be passed.
