I want to start a new project in ASP.NET core MVC web application. In the past I'm used to starting with the code, I create the code and I create the dbContext and I make the migration of the data Add-Migration and Update_Migration and finally I can get my database. This time I want to start with the database first, I loaded SSMS(SQL server management studio) and created the database and after I want to generate the classes from the database but It didn't work, I cannot find the ado.net entity data model in visual studio 2022.
I tried to solve this problem by myself, I added these packages(in the picture below) but also it didn't work
Can you please suggest what I am doing wrong?

So we are trying to work on creating a SSAS model for a data analysis project. Firstly, we made some changes in Visual Studio using SSDT and deployed the model to connect from a Reporting Service. We were logging in with multiple Windows Accounts into the VM and opening the same solution file to try to collaborate on the same.
However
we don't find any of the previous changes in the file anymore
trying to connect from the Reporting Service we find multiple models
created with a common name structure Model Cube_*Windows Account Name*.
Can this problem be solved if we use one common Windows account for doing the development and deployment of the model? What's the best way to collaborate in such a scenario?
I have a Visual Studio solution that has a few projects in it.
One project is based around an Entity Framework model .edmx.
Another project is an SQL Database project.
I can currently 'Update Model from Database...' in the .edmx.
I can also use 'Schema Compare...' in the SQL Database project to update the database.
I would rather not have to push the changes from the SQL Database project to the database, then update the .edmx from the database.
I would like to update the .edmx from the SQL Database project directly. Is this possible?
NOTE: this may not be a great solution having both projects, but it is a legacy product that uses Entity Framework. At one time, the project was Database First, and the .edmx would follow the changes. However, we want to track our SQL schema changes with the SQL Database project. Both projects work well to solve their individual problems, but don't quite work together?
I am working in mvc 5, visual studio 2013 and i am totally new to it. I made a new application and it has it's local db attached with it.
I just want to make my database in sql server management studio but i dont want to make database manually. i just want to create the required tables in sql server mgmt studio automatically and then i will change the connection strings manually.
I need to know the way of doing this, please let me know the steps of doing the same ?
Need guidance. Thanks a lot.
You can go with Entity Framework. You will need to choose Model first because you want to create your DB from SQL Management Studio.
You'll find a lot of tutorials related to this approach.
Getting Started with Entity Framework 6 Database First using MVC 5
In order to create an ERD diagram for new projects I have been using Visual Studio's entity framework designer. Essentially I'm creating a "dummy project", adding entity framework via Nuget and diagramming away (I don't use Microsoft's Entity Framework thus the dummy project).
Is there another way to create such diagrams natively within Visual Studio 2010 Ultimate?
Assuming you already have a database, you can easily generate an ERD following the steps below.
Ensure you installed either Microsoft SQL Server Data Tools or Microsoft Web Developer Tools in order to get the Entity Data Model Designer.
These are the steps to generate an entity relationship diagram. It was tested in VS2012
Open Visual Studio
Create a project or open an existing project
(must be Visual Basic, Visual C# project, or Console Application)
Right-click the project and choose Add -> New Item…
Under Visual C# Items select “Data”
Select the template “ADO.NET Entity Data Model”
Give it a name and click “Add”
Select “Generate from database” or “Empty model”
If “Generate from database” selected enter connection
info, choose the database objects and done!
The model is stored as a “.edmx” file.
I'm doing a web app using EF 4.0, and taking the "model first" approach - so I define all my entities, generate a DDL and create a database structure based the model.
Now, every time something changes in the model, I regenerate the DDL and the database structure is recreated from scratch - tables are dropped and recreated. In this process, I lose all configuration data that was already. This is fine for now, but going forward, once the app goes to production, how will I be able to upgrade the database if I decide to change something?
To simplify, (how) can I upgrade the database from the model and keep all the data?
Thanks!
You need another workflow or T4 templated for DB generation. It is already available in Entity Designer Database Generation Power pack extension for Visual Studio 2010. The only problem is that these workflows are using database tools from Visual Studio which are only available in Premium and Ultimate edition.
If you don't have VS 2010 Premium or Ultimate you must deploy new DB to test environment first and write diff script by yourselves or buy some diff script generator - I recommend DB tools from Red Gate.
