Is there any difference between the { e.MapControllers(); } and the e.MapControllers() ?

Hi everyone in

C#

C#

C#

C#, when using lambda expressions with the

UseEndpoints

UseEndpoints

UseEndpoints

UseEndpoints method, what's the difference between including curly braces and omitting them?
From my code example :

public void Configure(IApplicationBuilder app)
{
    ... //my other codes 
    app.UseEndpoints(e => e.MapControllers());

    app.UseEndpoints(e  => { e.MapControllers(); });
}

public void Configure(IApplicationBuilder app)
{
    ... //my other codes 
    app.UseEndpoints(e => e.MapControllers());

    app.UseEndpoints(e  => { e.MapControllers(); });
}

public void Configure(IApplicationBuilder app)
{
    ... //my other codes 
    app.UseEndpoints(e => e.MapControllers());

    app.UseEndpoints(e  => { e.MapControllers(); });
}

public void Configure(IApplicationBuilder app)
{
    ... //my other codes 
    app.UseEndpoints(e => e.MapControllers());

    app.UseEndpoints(e  => { e.MapControllers(); });
}

Is there any difference between the

{ e.MapControllers(); }

{ e.MapControllers(); }

{ e.MapControllers(); }

{ e.MapControllers(); }
and the

e.MapControllers()

e.MapControllers()

e.MapControllers()

e.MapControllers() ?
And why would the

MapControllers

MapControllers

MapControllers

MapControllers be called twice in this case?

Is there any difference between the { e.MapControllers(); } and the e.MapControllers() ?
