Setting Up ASP.NET Core 5.0
Before we delve into the latest features, let's set up a new ASP.NET Core 5.0 project.
First, ensure you have the .NET SDK 5.0 installed. Then, install the 'dotnet-ef' and 'dotnet-aspnet-codegeneration' tools for Entity Framework Core support. Use the following commands to create a new web application:
Creating a New Project
The command to create a new ASP.NET Core web application is:
```csharp dotnet new webapp -n MyWebApp ```
Here, 'webapp' is the template name, and 'MyWebApp' is the name of your application.
Running the Application
Navigate to your project directory and run the following command to start the application:
```csharp dotnet run ```
The application will be accessible at 'https://localhost:7283/'.
