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 :
دستور مورد نظر در Nuget :
PM> install-package AsyncAwaitCtp
و اما خطا
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.
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

PM > install-Package Microsoft-BCL-Async -Pre
که بازم با خطای زیر مواجه شدم.
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.

Build Accelerator, BuildXL for short, is a build engine originally developed for large internal teams at Microsoft, and owned by the Tools for Software Engineers team, part of the Microsoft One Engineering System internal engineering group. Internally at Microsoft, BuildXL runs 30,000+ builds per day on monorepo codebases up to a half-terabyte in size with a half-million process executions per build, using distribution to thousands of datacenter machines and petabytes of source code, package, and build output caching. Thousands of developers use BuildXL on their desktops for faster builds even on mega-sized codebases.

We don't prevent you from INSTALLING a package to Express ,since that just means 'writing some bits into the registry ', but it will never successfully load. As I mentioned in the other post, this is not a technological limitation, it is a business decision, one I disagree with, but I don't make these decisions

background-clip is one of those properties I've known about for years, but rarely used. Maybe just a couple of times as part of a solution to a Stack Overflow question. Until last year, when I started creating my huge collection of sliders. Some of the designs I chose to reproduce were a bit more complex and I only had one element available per slider, which happened to be an input element, meaning that I couldn't even use pseudo-elements on it. Even though that does work in certain browsers, the fact that it works is actually a bug and I didn't want to rely on that. All this meant I ended up using backgrounds, borders, and shadows a lot. I also learned a lot from doing that and this article shares some of those lessons.
