Azure Functions in .NET Core 3.1 : dependency Injection error

I have migrated some Azure Functions from .NET Core 2.2 to 3.1 and implemented the dependency injections for my function's class and I am getting this error:

Please check if the below steps help to:

As following this medium article, I resolved the same error when adding the dependency injections to one of the Azure Functions Project v3 migrated from .NET 2.2:

The error I got:

Microsoft.Azure.WebJobs.Script.WebHost: Registered factory delegate returns service Microsoft.Extensions.Logging.LoggerFactory is not assignable to container. Value cannot be null. (Parameter 'provider')

In Startup.cs File, registered the Serilog logger in the builder.Services.AddLogging method and Serilog Logger is created with its own instance and all the configurations.

// Startup.cs - Registering a third party logging provider
var logger = new LoggerConfiguration()
                .WriteTo.Console()
                .WriteTo.File("log.txt", rollingInterval: RollingInterval.Day)
                .CreateLogger();
builder.Services.AddLogging(lb => lb.AddSerilog(logger));

Also, please refer this Microsoft Documentation helps you regarding the usage of Dependency Injection in .NET Azure Functions.
