I'm having an issue with the #NVD API responding with what looks like random Unicode characters. It's very intermittent though. The System.Threading.RateLimiting package is working well though.

Well, the National Vulnerability Database is apparently doing away with their legacy feeds, so I'm throwing together a #NVD 2.0 API client for #NuGetDefense that will be published as a #nuget package for #dotnet 6+. This explains the issues I was having getting it to update the NVD feed recently.
