Error Message
Updating the 'this' or 'base' call of a constructor will prevent the debug session from continuing while Edit and Continue is enabled
This error occurs when you have a base or this call after the constructor declaration. Consider the following example:
class Program
{
public Program()
: this(10)
{
}
public Program(int a) { }
static void Main()
{
}
}
If you step into the application, then try to change this(10) to this(20), error 4066 occurs.
