Hi Alberto,
Query 1: SfTimePicker doesn´t show in the toolbar
In this
forum you have raised query about WPF platform but in the Attached image it was
looks like Winforms.
If you are
using Winforms platform there is no TimePicker control in winforms. You can
display and edit the time using SfDateTimeEdit Control.But editing the time
using its dropdown is not possible. Please refer the below documentation link
for your reference.

If you are
using WPF Platform means there is a SfTimePicker control, which is also
available in Toolbox

You can edit
the time using its dropdown (TimeSelector ) in this control. In WPF DateTimeEdit
control you can display the dropdown with TimeSelector.Please refer the below
documentation link for your reference.

Query 2: Cannot load file or assembly 'Syncfusion.Licensing,
Version=20.1460.0.48, Culture=neutral, PublicKeyToken=632609b4d040f6b4' or one
of its dependencies
Please uninstall all the syncfusion nuget and re-install the
nuget with required version. Make sure that all syncfusion assemblies refer
same version. If required, please update the correct version in app.config file and
hint patch in csproj file.

Gokul T.
