I'm using the scaffold command line because of the previously reported MS bug, to make a DataGrid page, the scaffolding completes but it makes a cshtml page with an ejs_grid instead of a razor page with a DataGrid control. It seems like its getting the project type wrong, which is a Blazor server side project made with the wizard.
The command does report an exception:
Scaffolding failed with these exception:System.NullReferenceException: Object reference not set to an instance of an object.
at syncfusion_scaffolding.Model.GetEntitySet(String dbContextTypeName, String dbModelTypeName, String projectName) in D:\2\vsext_scaffolding_command_line\Model.cs:line 139
but carries on and makes the Controller and cshtml view
