Install Microsoft.EntityFramework.Design through the NuGet package manager or the command line if you have followed the error message instructions.

‘But it was working fine for my other scaffolded item’ this item is in the same project?

Hi Jerry Cai,

Good to see you again for assistance.

Hi,Teena
Thank you for you still remembering me, try to make sure the packages version are right, if you can't use 6.0 version, try back to 5.0.* version. Do you have more error code?
Best Regards,

Hi Jerry Cai,

Thanks for the explanation, here is the scenario.

II started my project with asp.net core 3.1, all those packages were installed automatically when i scaffolded the item and was able to do the migrations also.

After upgrading visual studio version and target framework of my project to .net core 5,im getting this issue.

And one more doubt is there any significant difference for core 3.1 and .net 5?

What is admin.Noticeboard? You cannot make the file name and the model name the same name

Hi @Jerry Cai-MSFT ,

I have created NoticeBoard folder inside Admin folder.The page names are automatically generated while scaffolding.
Same way i created Users pages which doesnt give any issues and one more thing i tried to create a sample project with .net core 3.1 ,but the im facing the same issue .(Before upgrading visual studio 16.10.3 i havent faced such issues.) not able to scaffold item and do the migrations.

Thanks,
