Fix: 

- Download packages from the URL mentioned in the above error and place them in location:  
C:\Users\UserName\.vscode\extensions\ms-vscode.csharp-1.14.0\.debugger
  and for omnisharp copy the files in:  
C:\Users\UserName\.vscode\extensions\ms-vscode.csharp-1.14.0\.omnisharp

This should fix the issue.
