Hi Sajad yousefi,

Welcome to MSDN forum.

According to your description, please check if the .NET Core 2.2 SDK and Runtime has been installed on your new system. The download link: 

https://dotnet.microsoft.com/download/dotnet-core/2.2

Then re-run your project to check if it could work.

Any feedback will be greatly expected.

Best Regards,

Dylan
