I have method in Class which is implementation of Interface. When I made it Explicit implementation I got compiler error
The modifier 'public' is not valid for this item Why it is not allowed to have public for explicit interface implementation ?

The Interface BodyAll abstract, default, and static methods in an interface are implicitly public , so you can omit the public modifier. In addition, an interface can contain constant declarations. All constant values defined in an interface are implicitly public , static , and final .
The error thrown is usually “Cannot implement an interface member because it is not public”. If an interface member method is implemented in your class without an access modifier, it is by default private. To change the visibility, you can either change the interface from public to internal.
Resolving conflicts here ..... "Implicit Implementation" - means just simple implementation of a particular method having same name and same signature which belongs to the same class itself, where as "Explicit Implementation" - means implementation of a method using their Interface name having same name and signature ...
1) Interface members are only visible to code outside of the interface based on the rules of the respective visibility level. public : Interface members in C# are public by default, so this works.
The reason for an explicit interface implementation is to avoid name collisions with the end result being that the object must be explicitly cast to that interface before calling those methods.
You can think of these methods not as being public on the class, but being tied directly to the interface. There is no reason to specify public/private/protected since it will always be public as interfaces cannot have non-public members.
