Create a release with Octopus Client API

gistfile1.cs

var server = "http://yourserveraddress:8065/"; //Your server and IP address
var apiKey = "API-XXXXXXXXXXXXXXXXXXXXXXXXX";             // Get this from your 'profile' page in the Octopus web portal

	var endpoint = new OctopusServerEndpoint(server, apiKey);
	var repository = new OctopusRepository(endpoint);
	
	var projectId = "projects-225"; //your project id
	
	//This pulls out the info you need, the same call that's made on the Create Release page in the UI
	var template = repository.Client.Get<Octopus.Client.Model.ReleaseTemplateResource>("/api/deploymentprocesses/deploymentprocess-" + projectId + "/template");

	
	var release = new Octopus.Client.Model.ReleaseResource();
	release.Version = template.NextVersionIncrement;;
	release.ProjectId = projectId;
	foreach (var package in template.Packages)
	{
		release.SelectedPackages.Add(new Octopus.Client.Model.SelectedPackage(package.StepName, package.VersionSelectedLastRelease)); //Use a new package version if you know it
	}
			
	var result = repository.Releases.Create(release);

This doesn't work any more post-channel introduction.

Hi, this works.
```
var endpoint = new OctopusServerEndpoint("http://localhost:8099", "API-XXXXXXXXXXXXXXXXXXXXX");
var repository = new OctopusRepository(endpoint);

        var octoenv = repository.Environments.GetAll().FirstOrDefault(x => x.Name == "Dev");
        var projects = "project1,prokect2,project3".Split(',');
        foreach (var project in projects)
        {
            var octoproj = repository.Projects.Get(project);                
            var octoproc = repository.DeploymentProcesses.Get(octoproj.DeploymentProcessId);
            var channel = repository.Client.Get<ChannelResource>("/api/projects/" + octoproj.Id + "/channels");
            var octotemplate = repository.DeploymentProcesses.GetTemplate(octoproc, channel);
            var release = new ReleaseResource();
            release.Version = "1.0.0.15";
            release.ProjectId = octoproj.Id;
            foreach(var packages in octotemplate.Packages)
            {
                var selectedpackage = new SelectedPackage();
                selectedpackage.StepName = packages.StepName;
                selectedpackage.Version = "1.0.0.15";
                release.SelectedPackages.Add(selectedpackage);
            }
            var crRelease = repository.Releases.Create(release);
            var newderpl = new DeploymentResource();
            newderpl.ReleaseId = crRelease.Id;
            newderpl.ProjectId = octoproj.Id;
            newderpl.EnvironmentId = octoenv.Id;
            repository.Deployments.Create(newderpl);
            //release.SelectedPackages.Add(new SelectedPackage())
        }
