.NET Core 1.0.1 Entity Framework – Scaffolding

If you are using .NET Core version 1.0.1, you might have faced some issues to auto-generate database context and Model. There is one more option available to generate database context using command prompt.  

But you have to take care of adding supported/matched DLL reference from Nuget/Nexus.

Go to “project.json” file and make sure you have added following references

"dependencies": {     "Microsoft.NETCore.App": {       "version": "1.0.1",       "type": "platform"     },     "Microsoft.AspNetCore.Diagnostics": "1.0.0",     "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",     "Microsoft.AspNetCore.Server.Kestrel": "1.0.1",     "Microsoft.Extensions.Logging.Console": "1.0.0",     "Microsoft.Entityframeworkcore.Sqlserver": "1.0.0",     "Microsoft.EntityFrameworkCore.SqlServer.Design": "1.0.0",     "Microsoft.EntityFrameworkCore.Design": "1.0.0-preview2-final"   },   "tools": {     "Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final",     "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final"   },

Now go to the folder where “project.json” file exist and open command prompt.

1. Generate database Model for selected table only

                C:/Ritesh/EFScafoldingDemo:> dotnet ef dbcontext scaffold “Server={db server name},{port number};Database={db name};Trusted_Connection=True;” Microsoft.Entityframeworkcore.Sqlserver –t “Product”,”Order”

1. Generate entire database Model    

C:/Ritesh/EFScafoldingDemo:> dotnet ef dbcontext scaffold “Server={db server name},{port number};Database= db name};Trusted_Connection=True;” Microsoft.Entityframeworkcore.Sqlserver

There are multiple option available to generate database model for .NET Core entity framework, you can see from Microsoft site for more detail

After above command executed successfully you can see, dbProductContext.db , Product.cs, Order.cs files.
