NETSDK1195: Trimming, or code compatibility analysis for trimming, single-file deployment, or ahead-of-time compilation is not supported for the target framework.

NETSDK1195 indicates that you're using a feature of the SDK which is not available for the selected target framework. The following features depend on the ILLink pack, which is only available when targeting netcoreapp3.0 and above:

• Trimming (via PublishTrimmed or PublishAot)
• Trim analysis (via PublishTrimmed, PublishAot, IsTrimmable, IsAotCompatible, or EnableTrimAnalyzer)
• Single-file analysis (via PublishSingleFile or EnableSingleFileAnalyzer)
• Ahead-of-time compilation analysis (via PublishAot or EnableAotAnalyzer)

To resolve this error, either target a supported TargetFramework, or turn off the setting that requires the ILLink pack.
