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. 

These are the customer-reported issues addressed in this version:

Visual Studio crashes when you open a solution with a test project.
Visual Studio Freezes in Debug with Chrome.
Failure to install HelpViewer.
UI delay while typing R code.
C# 7.0 Regression in Tuples.
Xamarin - Dynamic Type Platform not supported exception.
Xamarin – Dynamic object is not supported.
Xamarin - Xamarin.iOS: ArgumentNullException for instruction parameter in Mono.Linker's MarkException() method.

سپس کلید پکیج  را زده تا پکیج مورد نظر آماده شود. دقت داشته باشید که بعد از انتخاب کامپایلر متلب، حجم پکیج نزدیک به 400 مگابایت خواهد شد. پکیج مورد نظر بصورت یک فایل exe فشرده خواهد شد.
معمولا پکیج شامل فایل‌های زیر باید باشد :

بعد از طی مراحل فوق نوبت به تیم برنامه‌نویسی دات نت می‌رسد. بعد از دریافت پکیج از تیم برنامه‌نویسی متلب در صورتیکه بر روی سیستم هدف کامپایلر متلب و یا خود متلب نصب نیست باید از داخل پکیج این کامپایلر نصب شود.
دقت داشته باشید که ورژن کامپایلر بر روی سیستم باید با ورژن پکیج دریافتی یکی باشد.
در VS یک پروژه کنسول ایجاد کنید و از فولدر پکیج پروژه دریافتی در زیرفولدر distrib فایل makeSqr.dll را به رفرنس برنامه VS اضافه کنید.
در ادامه از مسیر نصب کامپایلر فایل MWArray.dll را هم به رفرنس پروژه اضافه کنید. این فایل جهت تبادل داده اپلیکیشن با کامپایلر متلب مورد استفاده قرار می‌گیرد.

This article dives into the mock questions I would ask, along with responses that are my personal best guess to the answers. Could my answers not reflect actual opinions shared by the team at Microsoft? Sure, but I'm hoping folks from the .NET team can jump in to correct me if I am way off base.

This is a rather interesting time for .NET – what's being done shapes the future of .NET for the next decade. Let's ask the honest questions and hopefully all of us will understand the new .NET ecosystem a little better. 

Nulls are a huge source of exceptions and bugs in many programming languages today.
