This recipe explains, on using .NET standard extension methods in full framework app similar to one in .NET Core application. This also helps in leveraging a number of Steeltoe extension methods.
Add a class in the root of the application or under App_Start, called BootConfig.cs
Add the below nuget packages (preferably latest versions)
Add the below code into the class
public class BootConfig
{
static IHost host;
public static void Configure(string environment)
{
host = new HostBuilder()
.ConfigureAppConfiguration((builderContext, configBuilder) =>
{
//Add your IConfiguration builder extensions methods here
})
.ConfigureServices((builderContext, services) =>
{
//Add your IServiceCollection builder extensions methods here
})
.ConfigureLogging((context, loggerFactory) =>
{
//Add your ILoggerFactory extensions methods here
})
.Build();
}
public static T GetService<T>()
{
return host?.Services?.GetService<T>();
}
}
In Application_Start method of Global.asax.cs class, call the Configure method, which will create DI container, inject configurations and even configure logging as provided
public void Application_Start(object sender, EventArgs e)
{
...
BootConfig.Configure("development"); //pass in the enviroment variable here (hardcoded for sample purposes only)
}
You can also access the registered services using BootConfig.GetService<T>() method, anywhere from the applications.
Note: Incase if the application uses any DI framework, you can populate these services into their containers, where you may no need the
BootConfig.GetService<T>()method.
