.NET Framework 4.7.2 Class Library and .NET 6.0 Razor project

Question

We have a deployed Razor project on our IIS server. We also have a separate DLL project used by a desktop based application. There is functionality in the DLL that we would like to call from our Razor web site. Is this possible given that the Razor web site is.Net 6 and the class library is.Net framework 4.7.2?

Answer 1

No, it's not possible. What you might be able to do is change your class library to target .NET Standard 2.0, and then your .NET Framework 4.7.2 app and your .NET 6 app should both be able to reference it.
