NUnit Analyzers 4.7 - April 1, 2025
The release primarily add another diagnostic NUnit4002 - and associated codefix - to help simplify
EqualTo constraints when the expected value is a simple constant - e.g. true, false, 0, or
default. The release also removes some false positives for Nunit1029.
As tooling contributions the analyzers now build using .NET8.0 and also analyzers and codefixes are
now split into separate projects as only editors should load codefixes.

Issues Resolved
Features and Enhancements
