مقدمه ای بر برنامه نویسی همزمان

What is concurrent programing? Simply described, it’s when you are doing more than one thing at the same time. Not to be confused with parallelism, concurrency is when multiple sequences of operations are run in overlapping periods of time. In the realm of programming, concurrency is a pretty complex subject. Dealing with constructs such as threads and locks and avoiding issues like race conditions and deadlocks can be quite cumbersome, making concurrent programs difficult to write. Through concurrency, programs can be designed as independent processes working together in a specific composition. Such a structure may or may not be made parallel; however, achieving such a structure in your program offers numerous advantages.

مثال هایی از نحوه نوشتن PBI

News

As a site visitor, I can read current news on the home page.
As a site visitor, I can access old news that is no longer on the home page.
As a site visitor, I can email news items to the editor. (Note: this could just be an email link to
the editor.)
As a site a site editor, I can set the following dates on a news item: Start Publishing Date, Old
News Date, Stop Publishing Date. These dates refer to the date an item becomes visible on the site (perhaps next Monday), the date it stops appearing on the home page, and the date it is removed from the site (which may be never).
As a site member, I can subscribe to an RSS feed of news (and events? Or are they separate?).
As a site editor, I can assign priority numbers to news items. Items are displayed on the front page based on priority.

شروع کار با Docker

Almost overnight, Docker has become the de facto standard that developers and system administrators use for packaging, deploying, and running distributed applications. It provides tools for simplifying DevOps by enabling developers to create templates called images that can be used to create lightweight virtual machines called containers, which include their applications and all of their applications’ dependencies.

انجام کارهای زمانبندی شده در برنامه‌های ASP.NET توسط DNT Scheduler

من این تغییرات رو اعمال کردم

public static Task RunAndDispose(Func<Task> action)
{
        try
        {
                action();
        }
        finally
        {
                System.Diagnostics.Trace.WriteLine("Finaly");

                if (!HttpContextLifecycle.HasContext())
                {
                    new HybridLifecycle().FindCache(null).DisposeAndClear();
                }
        }
        return  Task.FromResult(0);
}

و متد RunAsync

public override async Task RunAsync()
{
        await SemaphoreSlim.WaitAsync();

        try
        {
                if (this.IsShuttingDown || this.Pause)
                    return;

                await IoCWrapper.RunAndDispose(async () =>
                {
                    var draftsService = IoCWrapper.GetInstance<IBlogPostDraftsService>();
                    await draftsService.RunConvertDraftsToPostsJobAsync();
                });
        }
        finally
        {
                SemaphoreSlim.Release();
        }
}
