Build-Time Verification + +Each project generates a `BuildInfo.fs` file at build time using MSBuild targets: + +```xml + + + +``` + +This captures actual build-time information, allowing tests to verify which compiler was actually used. + +### 4. Test Flow + +For each scenario: +1. **Clean** previous builds to ensure isolation +2. **Pack** the library with specified compiler (creates NuGet package) +3. **Build** the application with specified compiler, referencing the packed library +4. **Run** the application and verify: + - Anonymous records work correctly across compiler boundaries + - Build info confirms correct compilers were used + - No runtime errors or data corruption + +### 5. Anonymous Record Testing + +The library (`CompilerCompatLib`) exposes APIs using anonymous records: +- Simple anonymous records: `{| X = 42; Y = "hello" |}` +- Nested anonymous records: `{| Simple = {| A = 1 |}; List = [...] |}` +- Complex structures mixing anonymous records with other F# types + +The application (`CompilerCompatApp`) consumes these APIs and validates that: +- Field access works correctly +- Nested structures are properly preserved +- Type information matches expectations + +This ensures the binary pickle format remains compatible even when compilers change. + +## Running the Tests + +**As part of test suite:** +```bash +dotnet test tests/FSharp.Compiler.ComponentTests/FSharp.Compiler.ComponentTests.fsproj +``` + +**Standalone script:** +```bash +dotnet fsi tests/FSharp.Compiler.ComponentTests/CompilerCompatibilityTests.fsx +``` + +## Extending the Test Suite + +To add more compatibility tests: +1.
