ASP.NET 5 beta7 is now available both on NuGet and as a tooling update to Visual Studio 2015! This release also includes the first public preview of the .NET Execution Environment (DNX) for Mac and Linux based on .NET Core – no Mono required.

                                                 پس از نصب، این نسخه را می‌توانید در کنار نسخه‌ی اصلی، همزمان بر روی سیستم داشته باشید. 

• برای نصب کلی بر روی سیستم،  اینجا کلیک کنید و نسخه‌ی SDK Installer مناسب دستگاه خود را دانلود کنید (64 یا 32 بیتی).

• برای استفاده‌ی از EF Core آن در پروژه جاری می‌توانید آن‌‌را از اینجا  دانلود و یا بوسیله‌ی دستور زیر نصب کنید:
  

Install-Package Microsoft.EntityFrameworkCore -Version 2.2.0-preview3-35497

3- پس از نصب، ویژوال استودیوی preview را از همان مسیر visual studio، اجرا کنید. یک پروژه‌ی جدید از نوع وب را ایجاد کنید و فریمورک را بر روی بالاترین مقدار آن قرار دهید؛ مثل تصویر زیر:

بعد از ایجاد پروژه، می‌توانید در solution Explorer، ارجاعات جدید را مشاهده کنید:
