Sequence contains more than one matching elelment

Hi all,

I am working with sitefinity 7.0.

I have eCommerce  enable in my cms and have some dummy product manually created.

I have created some product by API also.Now when i am clicking the Products menu under eCommerce section, it shows an alert shows ,says that "Sequence contains more than one matching elelment"

I am not able browse any products ?

Given below is the code that i have used?

CatalogManager manager = CatalogManager.GetManager();
            EcommerceManager ecommerceManager = EcommerceManager.GetManager();
            
            foreach (var myProduct in myProducts)
           

                if (manager.GetProducts().Where(t => t.Title == myProduct.Title).SingleOrDefault() != null)
               
                    continue;     // Product already exists
               

                ProductType productType = ecommerceManager.GetProductTypes().Where(t => t.Title == myProduct.ProductTypeName).SingleOrDefault();
                if (productType == null)
               
                    continue;      // Product Type does not exist
               

                Product product = manager.CreateProduct(productType.ClrType);
                product.ClrType = productType.ClrType;

                product.Title = myProduct.Title;
                product.AssociateBuyerWithRole = Guid.Empty;
                product.DateCreated = DateTime.Now;
                product.Description = myProduct.Description;
                //product.IsShippable = myProduct.IsShippable;
                product.Price = myProduct.Price;
                //product.SaleEndDate = myProduct.SaleEndDate;
                //product.SaleStartDate = myProduct.SaleStartDate;
                //product.SalePrice = myProduct.SalePrice;
                product.Sku = myProduct.Sku;
                product.UrlName = Regex.Replace(myProduct.Title.ToLower(), @"[^\w\-\!\$\'\(\)\=\@\d_]+", "-");
                product.Visible = true;
                //product.Weight = myProduct.Weight;

                product.Status = Telerik.Sitefinity.GenericContent.Model.ContentLifecycleStatus.Master;

                manager.Provider.RecompileItemUrls(product);
                manager.SaveChanges();

                var contextBag = new Dictionary<string, string>();
                contextBag.Add("ContentType", product.GetType().FullName);

                string workflowOperation = "Publish";

                WorkflowManager.MessageWorkflow(product.Id,
                    product.GetType(),
                    "OpenAccessDataProvider",
                    workflowOperation,
                    false,
                    contextBag);

             
            ​

 Any idea on this?
