Use .NET 6 class library in >NET 4.7 ASP.NET Website [duplicate]

Question

Is that possible that a class library which is created in >NET 6 can be used as reference in ASP.NET Website created in .NET 4.7 framework

I didn't try any thing yet

Only if that class library is targetting .NET Standard 2.0 - otherwise no, you can't do that — marc_s

This has been asked and answered multiple times, and is fully documented. .NET 6 is .NET Core 6 and can't be used in .NET Framework. .NET Framework can only use .NET Framework or .NET Standard 2.0 libraries — Panagiotis Kanavos

If you can build the .NET 6 package as .NET Standard library then yes. Otherwise not.

For example a .NET Standard 2.0 library can be used in:

.NET Framework 4.6.1, 4.6.2, 4.7, 4.7.1, 4.7.2, 4.8, 4.8.1

And it has to be .NET Standard 2.0 - not 2.1 - to support the "old" .NET framework ..
