@0x56 @hallmarc this led me to google the difference--sounds like the nomenclature is similar to powershell. plain .Net is a windows-only experience but ".net core" is their effort to bring .net cross-platform.
or so says https://radixweb.com/blog/net-core-vs-net-framework anyway...
@0x56 oof. that does sound not-tenable then.
Any chance of decompiling binaries to recover the code?
