Visual Studio Code is a code editor redefined and optimized for building and debugging modern web and cloud applications. Visual Studio Code is free and available on your favorite platform - Linux, macOS, and Windows. ASP.NET Core - Write Apps with Visual Studio Code and Entity Framework This article explains how developers working on any platform can write data-oriented Web applications that run on Linux, Mac OS X, and Windows leveraging the new ASP.NET Core 1.0 and the Entity Framework, using Visual Studio Code as the development e.
Entity Data Model Wizard dialog. Select EF Designer from the database- Next-New Connection Enter your Server name- Choose your authentication. I am using SQL Server authentication. Thus, we need to provide the user name and password- Select your database- Test Connection- OK. It includes the sensitive data in the connection string-next-Choose version of Entity Framework. Include database objects to your model- Finish.
Visual Studio will generate a database diagram for the table. Now, you have an Entity Data Model file in your Model folder with all its necessary supportive files. The screen given below shows the auto generated entities file with DbContext inherited (Student.Context.cs). DbContext and DbSet are the ones that we need to establish a link between the model and the database. 'tbllogin.cs' class is one where you will see all the properties. Student.Context.cs tbllogin.cs I hope you liked it.
Here is and article explaining a good way to do this will little extra effort. The article describes comparing the SQL Database Project with the EF generated LocalDB to persist schema changes. Use EF to make schema/entity updates like you would normally in you development workflow. The use the EF database as your comparison DB to update your SQL Database project.
Going the other way means updating objects like stored procedures, logins, additional indexes, and other more administrative/fine tuning objects. There is a caveat though. EF does not have the tooling to detect these changes automatically, so be disciplined in using the right tools for the right jobs. EF for models and SQL DB Project for. Well, everything not controlled with EF code migrations:-).
Any serious development process should include some Source Control software and a plan for using the tool. Since Git, Mercurial, SVN, etc are freely available choose one. Git is commonly used by some of the largest organizations so you could choose to use that. There are, of course, many other source control tools. If you use this approach, regularly checking in the new versions of objects (schemas and code), you will have a trail of previous versions to compare against. Then you can look for changes that affect your code.
Of course, Microsoft's SQL Server Data Tools (SSDT) includes Schema Compare, as do many tools such as Red Gate, Idera, and so forth. This should give you the tools you need to track the changes in your schemas and changes in the code as well. You need to look into Migrations. Code First 'Migrations' handle incremental changes in the data model. Please see the following two resources to start with:. I assume that the EF source code is already in source control.
If you do any manual updates outside of the EF model (indexes perhaps) then you will need to add those to a separate folder in the project and source control so that you have a record of it, and hopefully the check-ins of any 'manual' scripts are done at the same time as the code so that the changes can be matched up when viewed historically.
