Start with the linked Diff between the baseline and compare commits, then inspect the SOD - Android HelloWorld Extracted Size performance report and its ADX graph. Compare the listed ARM64 Windows CoreCLR measurements for the affected .so, .dll, and package artifacts. Done means identifying and addressing the regression across the reported measurements, then confirming the results against the same benchmark.
