Compiled time error in .net framework 4.6.1 ?

Sanket Jain

I started work on Console application which is already completed in .net framework 4.6.1 but I have .net framework 4.5,so I upgrade my framework to 4.6.1.

After that on following code I got "Syntax error, ':' expected" this error.

Disconnected?.Invoke(this);

The following is working on my collegues system.

So how to resolve this issue ?

No,
I am not using ternary operator.
C# coding only.

Looks, you are trying to use the Ternary operator. If so, please follow below format
condition ? first_expression : second_expression;

If it is not the case then, can you please post the code snippet to help you better?
