Alternatively tried manual installation and still get error even after rebuilding project. The following error:

dotnet : Could not find any project in C:\Users\awise303\source\repos\ContosoUniversity\.
At line:1 char:1

• dotnet add package Microsoft.VisualStudio.Web.CodeGeneration.Design

    + FullyQualifiedErrorId : NativeCommandError
  
  
  

by following theses steps:

Create a Pages/Students folder.
In Solution Explorer, right-click the Pages/Students folder and select Add > New Scaffolded Item.
In the Add New Scaffold Item dialog:
In the left tab, select Installed > Common > Razor Pages
Select Razor Pages using Entity Framework (CRUD) > ADD.
In the Add Razor Pages using Entity Framework (CRUD) dialog:
In the Model class drop-down, select Student (ContosoUniversity.Models).
In the Data context class row, select the + (plus) sign.
Change the data context name to end in SchoolContext rather than ContosoUniversityContext. The updated context name: ContosoUniversity.Data.SchoolContext
Select Add to finish adding the data context class.
Select Add to finish the Add Razor Pages dialog.
The following packages are automatically installed:

Hmmmm @mostmate
Is there a .csproj file in C:\Users\awise303\source\repos\ContosoUniversity\ ?
Also confused to the error messages. Are you implying that executing dotnet add package Microsoft.VisualStudio.Web.CodeGeneration.Design is giving you

  + CategoryInfo          : NotSpecified: (Could not find ...soUniversity\`.:String) [], RemoteException
  + FullyQualifiedErrorId : NativeCommandError

We can move this issue to the scaffolding repo as well.

There's no .csproj file in C:\Users\awise303\source\repos\ContosoUniversity\ ?
I have just reinstalled the software, hoping this works @deepchoudhery

I entered this code to create a database after scaffolding process

Add-Migration InitialCreate
Update-Database

...but got this error (I have just updated the app but no change in response):
