I am learning Q# language. I am running the Example of "Teleportation_project" https://video2.skills-academy.com/en-us/azure/quantum/user-guide/how-to-work-with-qsharp-projects?tabs=tabid-qsharp%2Ctabid-qsharp-run But when I am running this example I got error. The error comes in the filr PrepareState in which we have a code

-------------------------------------------------------------------------------------------------------------
namespace PrepareBell { 

operation PrepareBellPair(left : Qubit, right : Qubit) : Unit is Adj + Ctl {

    H(left);

    CNOT(left, right);

}

}

The error I am getting is that
"entry point not found help: a single callable with the @EntryPoint() attribute must be present if no entry expression is provided(Qsc.EntryPoint.NotFound)". What Can I do that to elemenate the erroe. I debug the code but it also gives the same error. Thank you

    Hello, @Razeen ud-Din / PhD Scholar !

    Why am I getting an @EntryPoint() error in my Q# code?

    The @EntryPoint() attribute tells the Q# compiler where to begin executing the program. In programs with multiple function and operation definitions, the @EntryPoint() can be placed before any of the functions or operations and program flow starts from there and continues sequentially.

    If the @EntryPoint() attribute is not included in your Q# code, then you may get the following error:

    Entry point not found help: a single callable with the @EntryPoint() attribute must be present if no entry expression is provided(Qsc.EntryPoint.NotFound)
