enter image description hereI am experience this issue on my Nuget console, while running this command below. Please help me further thanks.
scaffold-DBContext "Data Source=(LocalDb)\MSSQLLocalDB; Catalog=eNtsaOnlineRegistrationDB;Integrated Security=True" Microsoft.EntityFrameworkCore.SqlServer-OutputDir Models
Please check you scaffold command.
You can use -ContextDir (PMC) and --context-dir (CLI) to scaffold the DbContext class into a separate directory from the entity type classes.
Try following command in PMC.
Scaffold-DbContext 'Data Source=(localdb)\MSSQLLocalDB;Initial Catalog=Chinook' Microsoft.EntityFrameworkCore.SqlServer -ContextDir Data -OutputDir Models
Also check your Models folder in project root directory with all folder access [read/edit] rights.check single space -OutputDir Models
You can find more detail on this link Reverse Engineering (Scaffolding)
Check you code especially for space characters etc. you have to put a space character before -OutputDir word...
Your code should be like this:
scaffold-DBContext "Data Source=(LocalDb)\MSSQLLocalDB; Catalog=eNtsaOnlineRegistrationDB;Integrated Security=True" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

I have a class library project that is referenced by a Winforms project in .NET Core 6.
In package manager, I run this when selected the class library project.
Scaffold-DbContext "Data Source=localhost;Initial Catalog=ControlParking;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False;ApplicationIntent=ReadWrite;MultiSubnetFailover=False" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models/DB -Force
After that, this error is shown:
PM> Scaffold-DbContext "Data Source=localhost;Initial Catalog=ControlParking;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False;ApplicationIntent=ReadWrite;MultiSubnetFailover=False" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models/DB -Force
Build started...
Build succeeded.
Could not load assembly 'Manager'. Ensure it is referenced by the startup project 'ParkControlWin'.
Where Manager is the class library project and ParkControlWin is the winforms project. ParkControlWin is actually referencing Manager project.
When I build the whole solution, no errors are shown, just some warnings, for example, variables are never used, and so on.
What may be happening here?
"Unable to find provider assembly 'Oracle.ManagedDataAccess.Core'. Ensure the name is correct and it's referenced by the project".
Dont Know why this error is comming while scaffolding.
Scaffold command i used.
Scaffold-DbContext -Provider Oracle.ManagedDataAccess.Core -Connection "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=18.88..)(PORT=11))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=CC)));User Id=CC;Password=C**8;" -OutputDir Models .
These are the package reference in my project
I am learning ASP.NET core 6 Multitier architecture. I tried making connection to database but I keep getting this error:
Error Number:4060,State:1,Class:11
Cannot open database "Blogging" requested by the login.
The login failed.
Login failed for user 'TECHRITOMA\TECHRITOMA Inc'.
I tried using the command :
Scaffold-DbContext "Server=(localdb)\mssqllocaldb;Database=Blogging;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models
and i was expecting the model class to be created.
As Sydney_dev said. First, Visual studio needs to successfully connect to the local database. Official document: SQL Server Express LocalDB.
.NET Core+EF Scaffold-DbContext command uses.
Scaffold-DbContext "Data Source=ip address;Initial Catalog=database name;User ID=account;password=password;" -Provider Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models;
Scaffold-DbContext "Data Source=ip address;Initial Catalog=database name;User ID=account;password=password;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models -Tables "Blog","Post" -ContextDir Context -Context BlogContext - ContextNamespace New.Namespace
Official document.
I have to create a layered .net core application including a database. I want to build the database entities with sql-first approach. The solution looks like this:
All of the projects are class libaries, except the FoodSupplementCompany.Program.
My question is, how can I use Scaffold-DbContext to generate the entities to the FoodSupplementCompany.Data project?
You can use the Package Manager Console:
cd .\FoodSupplementCompany.Data
dotnet ef dbcontext scaffold -s ..\FoodSupplementCompany.Program
The line cd .\FoodSupplementCompany.Data is for navigating into project directory where the DBContext is located.
And the line -s ..\FoodSupplementCompany.Program is for stating where is the startup project to use.
As the guide here states: scaffold-dbcontext
Example:
Scaffold-DbContext
"Server=(localdb)\mssqllocaldb;Database=Blogging;Trusted_Connection=True;"
Microsoft.EntityFrameworkCore.SqlServer
-OutputDir Models
-OutputDir -> The directory to put files in. Paths are relative to the project directory.
I am using the updated Nuget Package Manager Console in Visual Studio to scaffold models from a database I've connected from named Sail. When I enter the connection string into the Package manager console.
PM> Data Source=localhost;Initial Catalog=Sail;Integrated Security=True
I receive the following errors:
At line:1 char:12
+ Data Source=localhost;Initial Catalog=Sail;Integrated Security=True; ...
The Data section is missing its statement block.
Found my answer:The block below successfully generates models from the connected "Sail" SQL database.
Scaffold-DbContext –Connection "Server(localdb)\mssqllocaldb;Database=Sail;Trusted_Connection=True;"
(localdb)\mssqllocaldb;Database=Sail;Trusted_Connection=True;"
-Provider "Microsoft.EntityFrameworkCore.SqlServer" -OutputDir "Models" –Context "Sail" –Verbose -Force
