question

We've been getting sporadic fails when uploading our builds using the Powershell API, so I am trying to implement the process in C# to see if it works any better. Is there documentation anywhere for doing that?

I think it is almost working - I am getting the upload URL and it seems to upload my build OK. The Create Build step is failing, however. It's returning this:

Error MultiplayerServerBadRequest PlayFab.PlayFabErrorCode
+ ErrorDetails Count = 1 System.Collections.Generic.Dictionary<string, string[]>
ErrorMessage "MultiplayerServerBadRequest - ValidationError - There were errors during request validation." string
HttpCode 400 int
HttpStatus "BadRequest" string
RequestId "Failed to Enumerate RequestId. Exception message: Enumeration has not started. Call MoveNext." string

Here is how I'm trying to create the build:

 protected static void CreateBuild(string fileName, string Token, int port)
        {
            List<PlayFab.MultiplayerModels.Port> ports = new List<PlayFab.MultiplayerModels.Port>();

            PlayFab.MultiplayerModels.Port port = new PlayFab.MultiplayerModels.Port();
            port.Name = "game_port";
            port.Num = port;
            port.Protocol = PlayFab.MultiplayerModels.ProtocolType.UDP;

            ports.Add(port);

            List<PlayFab.MultiplayerModels.AssetReferenceParams> assets = new List<PlayFab.MultiplayerModels.AssetReferenceParams>();

            PlayFab.MultiplayerModels.AssetReferenceParams assetReferenceParams = new PlayFab.MultiplayerModels.AssetReferenceParams();
            assetReferenceParams.FileName = fileName;
            assetReferenceParams.MountPath = "C://Assets";

            assets.Add(assetReferenceParams);

            List<PlayFab.MultiplayerModels.BuildRegionParams> buildRegionParams = new List<PlayFab.MultiplayerModels.BuildRegionParams>();

            PlayFab.MultiplayerModels.BuildRegionParams buildRegionParam = new PlayFab.MultiplayerModels.BuildRegionParams();
            buildRegionParam.Region = "EastUS";
            buildRegionParam.MaxServers = 1; 
            buildRegionParam.StandbyServers = 0;
             
            buildRegionParams.Add(buildRegionParam);

            string buildName = System.IO.Path.GetFileNameWithoutExtension(fileName);

            var createBuildTask = PlayFab.PlayFabMultiplayerAPI.CreateBuildWithManagedContainerAsync(new PlayFab.MultiplayerModels.CreateBuildWithManagedContainerRequest()
            //PlayFab.PlayFabMultiplayerAPI.CreateBuildWithManagedContainer(new PlayFab.MultiplayerModels.CreateBuildWithManagedContainerRequest()
            {
                //AuthenticationContext = new PlayFab.PlayFabAuthenticationContext() { EntityToken = Token },
                BuildName = buildName,
                ContainerFlavor = PlayFab.MultiplayerModels.ContainerFlavor.ManagedWindowsServerCore,
                GameAssetReferences = assets,
                MultiplayerServerCountPerVm = 1,  
                Ports = ports,
                RegionConfigurations = buildRegionParams,
                StartMultiplayerServerCommand = "C:\\Assets\\Server.exe",
                VmSize = PlayFab.MultiplayerModels.AzureVmSize.Standard_D4as_v4

            });

            createBuildTask.Wait();

            if (createBuildTask.Result.Result != null)
            {
                Console.WriteLine("Success?" + createBuildTask);
            }
            else
            {
                Console.WriteLine("createBuildTask Error: " + createBuildTask.Result.Error.ErrorMessage);
            }
        }
