8 ویژگی جذاب Angular

I've been doing some work the last couple of weeks with Angular2. I really like it. Not just because it uses typescript, but also because it feels really natural and straightforward while working with it. No more string based dependency injection, or strange digest cycle stuff, it just seems to work. This last week I've migrated our beta-13 Angular app to the latest rc-1, and used that to keep track of the fun and easy stuff Angular 2 provides. Note though, that the application we're developing is really that complex, so I can only assume we'll run into more complex Angular2 features in the near future. For now, though, let me share some general tips and tricks we've encountered thus far (in no particular order). Oh, all examples are in typescript, since after using that, I really don't want to go back to plain old javascript (POJS?).

روش استفاده از Async&Await در Portable Class Library دات نت 4
چند وقت پیش زمانی که قصد داشتم از یک Portable Class Library  که تحت دات نت 4 بود توی پروژه ام استفاده کنم متوجه شدم که این نوع Class Library از فضای نام System.Threading.Task پشتیبانی نمی‌کنه. قصد داشتم که از این فضای نام برای بحث TPL توی پروژه ام استفاده کنم و چند تا متد Async بنویسم. زمانی که سعی کردم  با استفاده از Nuget؛ AsyncAwaitCTP رو نصب کنم با خطای زیر روبرو شدم.

دستور مورد نظر در Nuget :
PM> install-package AsyncAwaitCtp
و اما خطا
Install failed. Rolling back...
install-package : Could not install package 'AsyncAwaitCTP 1.0'. You are trying to install this package into a project that targets '.NETPortable,Version=v4.0,Profile=Profile3', 
but the package does not contain any assembly references that are compatible with that framework. For more information, contact the package author.
At line:1 char:1
دستور بالا برای نصب AsyncAwaitCTP در Class Library تحت دات نت 4.5 استفاده می‌شه.
خلاصه بعد از یکم جستجو متوجه شدم که باید از دستور زیر برای نصب TPL توی Portable Class Library تحت دات نت 4 استفاده کنم.
PM > install-Package Microsoft-BCL-Async -Pre
که بازم با خطای زیر مواجه شدم.
Install failed. Rolling back...
install-package : Could not install package 'Microsoft.Bcl 1.0.16-rc'. You are trying to install this package into a project that targets 
'.NETPortable,Version=v4.0,Profile=Profile3', but the package does not contain any assembly references that are compatible with that framework. For more information, contact the 
package author.
At line:1 char:1
+ install-package Microsoft.BCL.Async -Pre
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Install-Package], InvalidOperationException
    + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand
از اونجا که از دستور بالا مطمئن بودم و می‌دونستم که باید درست کار کنه فهمیدم اشکال کار از یه جای دیگه است. خلاصه بعد از یه جستجوی 25 دقیقه ای متوجه شدم که
Nuget نصب شده روی سیستم من Update نیست. برای همین به روش زیر عمل کردم .
از منوی Tools گزینه Extension And Updates رو انتخاب کردم. بعد از صفحه مورد نظر گزینه Updates روز از منوی سمت چپ انتخاب کردم و درنهایت گزینه Nuget Package Manager. مثل شکل زیر:


بعد از اتمام عملیات Update دوباره دستورات مورد نظر رو وارد کردم که به خوبی عملیات نصب CTP به اتمام رسید.
