Thanks for the PR, @jagreddyn7. I noticed you suggest uninstall other versions of .net core sdk and cuda. Can you provide more details on what are the .net core sdk and cuda versions that prevent Rocket from running on your dev machine? Testing on our side indicates Rocket is able to run with multiple .net core sdk (e.g., 2.2 and 3.1) and cuda (e.g., cuda 8.0 + cuda 9.1) on a Windows 10 host machine.

@ycshu086, I noticed that multiple versions of core and sdk were running into version conflict issues, resulting in build issues. I did not experiment with other versions of dotnet, in the interest of my personal productivity. I just got the 2.2 working, by uninstalling other versions of core and sdk. We can modify the uninstall directions and make it conditional on running into compilation issues.
