Guide to the CoreCLR Source Code
&gt;&gt; Just over 2 years ago Microsoft open-sourced the entire .NET framework,<p>Except they open-sourced a new .NET stack, not really the entire .NET Framework, .NET Core and .NET Framework are similar but not fully backwards compatible. I&#x27;ve been porting .NET Framework code to .NET Core and depending on how specialized your project is you may not always find the same libraries supporting your project. A project that perfectly compiles with .NET 2.0 will not just compile for .NET Core, at least not as easily as using a .NET Framework 2.0 project in .NET Framework 4.6. I love Microsoft and .NET but I think Core is executed poorly. You also have EntityFramework vs. EntityFramework Core which lacks features from EF which were deemed &quot;unused&quot; which bites some people in the face.
