Description
public partial class C {
public partial string M1(string dummyParam, out bool i); // error CS8795: Partial method 'C.M1(string, out bool)' must have an implementation part because it has accessibility modifiers.
public void M2(C c)
{
c.M1(null, out bool i);
_ = i.ToString(); // error CS0165: Use of unassigned local variable 'i'
}
}
Since this partial method must have an implementation (and we already error on it), we could suppress the error on the use of the unassigned variable.
