Could not load type 'System.Web.UI.WebResourceAttribute'

[yogster]

Hello, and thanks for your hard work creating this package.

I'm trying to use this package in a .Net 7 application, and I'm getting the following exception when calling Execute from a unit test:

System.TypeLoadException : Could not load type 'System.Web.UI.WebResourceAttribute' from assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

Stack trace below.

My understanding is that this package should work with .Net 6 and above... So why is it trying to use a .Net Framework 4.x assembly? What am I doing wrong? Cheers!

From the stack trace it looks like the KnownTypesResolver is trying to find the details for an early-bound assembly, and as part of that it's found a loaded assembly which has a WebResourceAttribute on it which it's then failing to load. We can't see from this stack trace what that assembly is, but you might be able to find this in the debugger.
