Deploying AWS Serverless lambda Application with AmazonServerlessApplicationRepositoryClient does not work?

问题

I want to deploy my ASP.Net Core Web Application project through a c# console application. It means I am trying to create a serverless lambda application on AWS without AWS Toolkit or CLI command. I want to do this with AWS SDK.
For this purpose I added below Nugets :

• AWSSDK.ServerlessApplicationRepository
• AWSSDK.Core
• AWSSDK.Lambda

at first step I am making a package with msbuild command. Then Zipped and upload on S3 bucket and in final step I am running below code. It does not show me any error but it is not in my function list.

        AmazonServerlessApplicationRepositoryClient clie = new AmazonServerlessApplicationRepositoryClient("AKIAJQVBDUUDGLXOEKYA", "HdoCIeKqtnKYVXB6y/HHnK6mTD2G556jqAp+bk3e", RegionEndpoint.EUWest1);
        CreateApplicationRequest createApplicationRequestObject = new CreateApplicationRequest()
        {
            Name = "ApplicationTest",
            Author = "Mike",
            Description = "Mike Desc",
            SourceCodeUrl = "https://region/bucketname/publishfolder/" + packageFileName,

        };
        CreateApplicationResponse createApplicationResponseObject = clie.CreateApplication(createApplicationRequestObject);

I can't find any any error in the CreateApplicationResponse object. Also status proeprty of the CreateApplicationResponse object is Created but I can not find any new Lambda application in Lambda->Application of console.

I had to use cloudFormation request and responses for deploying this kind of project. AWS SDK has many nice classes and functions that do it.
So I developed some methods that do it for me :

CheckAndFillBucketName();
CheckAndFillStackName();
CheckAndFillRegion();
MakePackage();
ZipPackage(zipPublishFolder, packageFileName);
UploadPackageToS3(zipPublishFolder, packageFileName);
UploadTemplateToS3(packageFileName);
var cloudFormation = new AWSCloudFormation(tempstack, templateUrl);
cloudFormation.CreateCloudFormationOnAWS();

for creating CloudFormation object, I created a class like this that do it for me :

public class AWSCloudFormation
{
    public string StackName { get; set; }
    public string TemplateUrl { get; set; }
    AmazonCloudFormationClient CloudFormationClient;
    public AWSCloudFormation(string stackName, string templateUrl)
    {
        CloudFormationClient = CreateCloudFormationClient();
        StackName = stackName;
        TemplateUrl = templateUrl;
    }

    public AmazonCloudFormationClient CreateCloudFormationClient()
    {
        var amazonCloudFormationConfig = new AmazonCloudFormationConfig
        {
            RegionEndpoint = RegionEndpoint.GetBySystemName(Program.AWSLambdaToolsJsonConfig.Region),
        };

        return new AmazonCloudFormationClient(Program.AccessKey, Program.SecretKey, amazonCloudFormationConfig);
    }

    static Stack GetStack(AmazonCloudFormationClient cloudFormationClient, string name)
    {
        return cloudFormationClient.DescribeStacks(new DescribeStacksRequest { StackName = name }).Stacks.First();
    }

    public void CreateCloudFormationOnAWS()
    {
        try
        {
            Log.Info(Program.LogPath, "Creating Cloud Information");
            var describeStacksRequest = new DescribeStacksRequest();
            var changeSetName = "changeset" + Program.PostfixExpression;
            var changeSetType = ChangeSetType.CREATE;

            if (CheckStackIsExist(CloudFormationClient, StackName))
            {
                changeSetType = ChangeSetType.UPDATE;
            }

            var createChangeSetRequest = new CreateChangeSetRequest
            {
                ChangeSetName = changeSetName,
                StackName = StackName,
                //TemplateBody = ServerlessTemplateBody,
                TemplateURL = TemplateUrl,
                ChangeSetType = changeSetType,
                Capabilities = new List<string> { "CAPABILITY_IAM" },
            };

            var createChangeSetResponse = CloudFormationClient.CreateChangeSet(createChangeSetRequest);

            WaitForChangeSet(CloudFormationClient, StackName, changeSetName);

            var executeChangeSetResponse = CloudFormationClient.ExecuteChangeSet(new ExecuteChangeSetRequest
            {
                ChangeSetName = changeSetName,
                StackName = StackName,

            });

            WaitForStack(CloudFormationClient, StackName);

            var generatedStack = GetStack(CloudFormationClient, StackName);
            Log.Info(Program.LogPath, "Output URL is : " + generatedStack.Outputs.Find(x => x.OutputKey == "ApiURL").OutputValue);
            Log.Info(Program.LogPath, "Creating Cloud Information Finished");
        }
        catch (Exception ex)
        {
