PackageGuard 2.10.0 is out. The new command "dependencies" finds NuGet package references you may not need, and packages that resolve to different versions.
Also: vulnerable packages first in the HTML report, and fairer risk scores.

When should a C# operation be a method rather than a property?
Use a method if it’s expensive, performs a conversion, returns a different result each call, or causes side effects.
Lazy-loading and internal caching are reasonable exceptions.

My weekly Claude Team limit got reset halfway the week and will reset again tomorrow. Did that happen to anybody else?
Properties should be stateless with respect to other properties. Setting DataSource then DataMember should have the same result as the reverse. Sounds trivial, but I've seen plenty of classes where properties were anything but simple.
