Microsoft’s Shared Source permits both organizations and individuals to access a program’s source code as a reference. This access provides developers with debug capabilities, which can be downloaded after satisfying certain eligibility criteria. The associated license may range from only code viewing for reference to permission for modification, which can be used for commercial and noncommercial purposes.
