In startup.cs file, I add custom application context to the services container:

    public void ConfigureServices(IServiceCollection services)
    {
        var connection = @"...";                
        // Add Entity Framework services to the services container.
        services.AddEntityFramework()
            .AddSqlServer()
            .AddDbContext<ApplicationDbContext>(options =>
                options.UseSqlServer(Configuration["Data:DefaultConnection:ConnectionString"]))
            .AddDbContext<MyContext>(options => options.UseSqlServer(connection));

...

In the Configure method of this same class, I can get an instance using this command:

app.ApplicationServices.GetService(typeof(MyContext)) as MyContext;

It works, because I have the app variable there.

In other business class, how can I get an instance of MyContext?

are you talking about `Dependency Injection` http://stackoverflow.com/questions/29083548/how-to-access-open-dbcontext-without-explicit-reference – MethodMan Aug 06 '15 at 18:53
Are you suggesting to pass context always it´s needed, right? – Beetlejuice Aug 06 '15 at 19:16
