| Scenario | How Developer Pack Helps | |----------|--------------------------| | Build an app that must run on Windows 7 with .NET 4.5.2 only | Ensures no accidental use of 4.6+ APIs. | | CI/CD pipeline (MSBuild) | Targeting pack allows /p:TargetFrameworkVersion=v4.5.2 . | | Debugging framework code | Installs PDBs for step-through debugging. | | Using older third-party libraries compiled against 4.5.2 | Reference assemblies match the exact API surface. | | Multi-targeting same codebase for 4.5.2 and 4.8 | Define conditional compilation symbols. |
