Which output does this concern exactly?

As per .NET SDK documentation (see here), DOTNET_SKIP_FIRST_TIME_EXPERIENCE is unsupported since .NET Core 3.0 and was replaced by DOTNET_NOLOGO.

That wasn't my question. I was asking what output is shown if this is not set.

[TheBlueSky]

The same output that not setting DOTNET_SKIP_FIRST_TIME_EXPERIENCE prior to .NET Core 3.0, which is the welcome message about the telemetry and some information and links.

You're not answering my question, and I'm not trying to be difficult either. I want to see the exact output that is suppressed by this variable to make sure that the SDK version is still included in the output as I find this is relevant for builds.

Something like this:

Welcome to .NET 8.0!

SDK Version: 8.0.100
