FastBuilder

FastBuilder is a Net 5 library that allows you to speed up a build process for faster iterations. FastBuilder is based on the idea of omitting the full build process that includes checking nuget packages and references. FastBuilder parses the output of a common "dotnet build" command and retrieves the full dependency graph and all roslyn command arguments. After the initial dotnet build, FastBuilder watches for changes to the source and dependencies. If only source files have been changed or added, FastBuilder changes the arguments and calls only the final roslyn command, omitting all preparation steps.

There are no dependencies, so it can be integrated into any project with minimal impact. However, FastBuilder does assume that the dotnet cli tools are installed and working correctly.
