NETSDK1138 should not be raised for libraries #28518
Description
Is your feature request related to a problem? Please describe.
This is more of a DCR.
NETSDK1138 is raised to notify users of EOL frameworks being targeted. This is too noisy for libraries.
Describe the solution you'd like
When I am targeting a library, the TFM decision is usually the lowest version of the framework that meets my needs, as I want as many users as possible to use my library.
The NETSDK1138 warning can be misleading when I'm building a library.
Notifying EOL when the project is likely to run on that runtime is great, and valuable, but only for executables.
