.NET 4.0 source code



I’m looking for .NET 4.0 source code from Visual Studio 2010.
In referencesource.microsoft.com site there is .NET in version 4.7, but I’m looking for 4.0 version.
Please share with old .NET 4.0 source code.
Best Regards
Wieslaw Kubala


I don’t think .NET 4.0 is open source.


Not true open source, but part of the .NET Framework source code was published since 3.5 version. ten years ago, so 4.0 should be available: https://weblogs.asp.net/scottgu/releasing-the-source-code-for-the-net-framework-libraries
