In this article, let's go through one of the most searched queries on Google, "File Upload in ASP.NET Core MVC". Uploading Images or other documents is a very basic and common requirement when it comes to building anything from a simple application to an enterprise-level solution. Let's build a small application with which you could upload files of any type to a file system location or to a centralized database table.
This article explains how to improve your ASP.NET Core sites' e-mailing capabilities to make things easier to manage and improve stability.
This is a sample appsettings.json file:
{
"ExampleConfig": {
"ValueA": "aaa",
"ValueB": "https://example.com",
"ValueC": 1234
}
}
This is our example model which we want to load from the configuration:
public class ExampleConfig
{
public string ValueA { get; set; }
public Uri ValueB { get; set; }
public int ValueC { get; set; }
}
Here’s how I read the model from the configuration:
public class ExampleCommandHandler
{
private readonly IConfiguration _configuration;
public ExampleCommandHandler(IConfiguration configuration)
{
_configuration = configuration;
}
public Task Handle(ExampleCommand)
{
var exampleConfig = _configuration
.GetSection(nameof(ExampleConfig))
.Get<ExampleConfig>()
?? throw new ConfigurationException(nameof(ExampleConfig));
// ...
}}
There is one thing you need to watch out for. To call the Get<T> method, use Microsoft.Extensions.Configuration.Binder NuGet package.
var currentlight = getcurrentlight();
string action = currentlight switch
{
TrafficLight.red => "stop",
TrafficLight.orange => "slow down",
TrafficLight.green => "go",
_ => "unknown",
}

}ASP.NET Core provides two primary methods allowing developers to cache information; IMemoryCache and IDistributedCache. Selecting the proper caching implementation requires an understanding of your application, your future goals, and the features of both options. This post explores cache strategies.
