CodeQL is a static analysis tool that can scan your code for vulnerabilities.  

It can be difficult  to write unit tests for code that accesses the file system. 

dotnet new console -o MyFirstWasiApp
cd MyFirstWasiApp
dotnet add package Wasi.Sdk --prerelease
dotnet build

دقت داشته باشید که این فیچر هنوز در مرحله Beta قرار دارد؛ و ممکن است در حین تهیه ایمیج با edge caseهای روبرو شوید به عنوان مثال من سعی کردم یک وب‌سرور ASP.NET Core (توسط Wasi.Sdk این امکان وجود دارد) را containerised کنم که در نهایت با خطای زیر مواجه شدم:

به ازای هر آیتمی که در شیء بازگشتی وجود دارد، با استفاد از متد each در jQuery یک li ایجاد می‌کنیم. همان طور که می‌بینید کلیه خواص، به شکل Fluent قابل اضافه شدن می‌باشد. سپس برای li یک رویداد کلیک که در صورت وقوع، متد FillData را با شناسه فید کلیک شده فراخوانی می‌کند و در آخر li را به المنت ul اضافه می‌کنیم.

برای هر کلیک هم مانند مثال بالا api را با شناسه‌ی فید مربوطه فراخوانی کرده و به ازای هر آیتم، یک سطر ایجاد می‌کنیم.

private static void FillData(string p)
        {
            jQuery.Ajax(new jQueryAjaxOptions()
            {
                Url = "/api/items/" + p,
                Type = "GET",
                Success = (d, t, r) => {
                    var content = jQuery.Select("#FeedItems");
                    content.Html("");
                    foreach (var item in (List<Item>)d)
                    {
                        var row = jQuery.Select("<div>").AddClass("row").CSS("direction", "rtl");
                        var link = jQuery.Select("<a>").Attribute("href", item.Link).Text(item.Title);
                        row.Append(link);
                        content.Append(row);
                    }
                }
            });
        }
