sure! in this tutorial, we will cover the concepts of authentication and authorization in the context of using sql server with identity, which is a membership system that adds login functionality to your application. we'll go through the setup, implementation, and code examples to help you understand how it all works.
overview
1. **authentication**: this is the process of verifying who a user is. in web applications, this often means logging in with a username and password.
2. **authorization**: this determines what an authenticated user is allowed to do. this can include access to certain resources or performing specific actions.
technologies used
sql server
asp.net core with identity
entity framework core
prerequisites
visual studio (or visual studio code)
sql server (local or remote)
.net sdk installed
step 1: create a new asp.net core project
1. open visual studio and create a new asp.net core web application.
2. select "web application (model-view-controller)".
3. check the "change authentication" button and select "individual user accounts".
4. click "ok" to create the project.
step 2: configure sql server
1. open `appsettings.json` in your project.
2. modify the default connection string to point to your sql server database.
```json
{
"connectionstrings": {
"defaultconnection": "server=your_server;database=your_database;trusted_connection=true;multipleactiveresultsets=true"
},
...
}
```
step 3: update the database
1. open the package manager console (pmc) from the tools menu.
2. run the following commands to create the database and apply migrations.
```powershell
add-migration initialcreate
update-database
```
step 4: set up identity configuration
make sure your `startup.cs` file is properly configured to use identity. you should have something like this in the `configureservices` method:
```csharp
public void configureservices(iservicecollection services)
{
services.adddbcontextapplicationdbcontext(optio ...
