## Sample of startup code for aspnetcore MVC

```csharp
public void ConfigureServices(IServiceCollection services)
{
    // make sure to add your queries and commands before the .AddPoweredSoftQueries and .AddPoweredSoftCommands
    AddQueries(services);
    AddCommands(services);

    // adds the non related to aspnet core features.
    services.AddPoweredSoftCQRS();
    
    services
        .AddControllers()
        .AddPoweredSoftQueries() // adds queries to aspnetcore mvc.(you can make it configurable to load balance only commands on a instance)
        .AddPoweredSoftCommands() // adds commands to aspnetcore mvc. (you can make it configurable to load balance only commands on a instance)
        .AddFluentValidation();

    services.AddSwaggerGen();
}
```
> Example how to add your queries and commands.

```csharp
private void AddCommands(IServiceCollection services)
{
    services.AddCommand<CreatePersonCommand, CreatePersonCommandHandler>();
    services.AddTransient<IValidator<CreatePersonCommand>, CreatePersonCommandValidator>();

    services.AddCommand<EchoCommand, string, EchoCommandHandler>();
    services.AddTransient<IValidator<EchoCommand>, EchoCommandValidator>();
}

private void AddQueries(IServiceCollection services)
{
    services.AddQuery<PersonQuery, IQueryable<Person>, PersonQueryHandler>();
}
```
