binlog-generation

To ensure MSBuild binlogs are generated for dotnet build and test commands, append the /bl:N.binlog switch to your commands. This automatically creates detailed binary logs for every execution, preventing data loss and simplifying build failure analysis.

An MSBuild binlog is a detailed binary log file recording all build execution data. You need it for troubleshooting dotnet builds when a build fails unexpectedly, allowing you to pinpoint the exact cause by analyzing the log without re-running the build.

To prevent overwriting previous MSBuild binlogs during multiple dotnet builds, use an incrementing counter for filenames like 1.binlog and 2.binlog. You must check for existing *.binlog files to determine the next sequential number and preserve build history.

Yes, the binlog generation approach works with dotnet pack and publish commands. It enforces mandatory binary log generation for all MSBuild-based commands, ensuring that pack, publish, test, and build operations consistently produce valuable diagnostic logs.

The best way to ensure every dotnet build generates a binlog without manual intervention is to enforce the mandatory appending of the /bl:N.binlog switch. This automatically captures detailed MSBuild execution data for all commands, guaranteeing logs are always available for failure analysis.
