Stack overflow was wrong then somehow ChatGPT knew what I was talking about when trying to set a dotnet environment variable in azure for an array in an app service. It has to be foo__0 not foo:0 so I broke production in a very nonobvious day for a day. At some point the foo__0 gets transliterated into foo:0 apparently?

The absolute worst location for this was, of course, the Azure or dotnet documentation sites. Cmon Microsoft you make both of these products surely this is a huge use case for your customers?
