Answer 1

Use the GUID-Generator of your choice or follow this link .

GuidAttribute Class

Provides an explicit System.Guid when an automatic GUID is objectionable.

It should only be compatible with the constructor of the Guid class:

The string passed to the attribute must be in a format that is a valid constructor argument for type Guid. To avoid conflicts with the Guid type, use the long GuidAttribute name explicitly. Only use the explicit GUID when the type must have a specific GUID. If the attribute is omitted, a GUID is assigned automatically.

Answer 2

The GUID property of the Type class. Try

 typeof(_Service).GUID; typeof(Ebil).GUID;
