Windows
For .NET Framework 4 applications, it is necessary to use the grdlic.dotnet.dll library from the directory: %ProgramFiles(x86)%\Guardant\Software Licensing Kit\api\lib\windows\dotnet\
For .NET Core 2.0 and above / Standard 2.0 and above / .NET 5.0 and above, it is necessary to use the grdlic.dotnet.core.dll library from the directory: %ProgramFiles(x86)%\Guardant\Software Licensing Kit\api\wrappers\dotnet\
For software products licensing and protection, special classes and methods are implemented in the Guardant Licensing API.
