Pull Request Overview
Fixes a crash when using MSBuild's preprocess functionality by preventing logger registration during preprocessing operations. The change ensures that loggers are only registered when actually building projects, not when preprocessing them.
- Modifies ProjectCollection constructor to conditionally register loggers based on preprocess mode
- Adds comprehensive test coverage for preprocessing with various verbosity and parallelization options
