String interpolation: a bug in c# compiler?

Question

string Test(bool @bool) => $"you're {@bool?"hired":"fired"} Have a nice day!";

The code above results in compilation error. But why? Notice that string test = $"this {"is"} working"; works.

What compilation error?

The colon ends the interpolation. Just parenthesize the condition :

string Test(bool @bool) => $"you're {(@bool ? "hired":"fired")} Have a nice day!";

For this issue you you can not use of ?,: of some thing like these, for using of these you have to set Exactly your condition should put in () like:

string Test(bool @bool) => $"you're {(@bool ? "hired":"fired")} Have a nice day!";

You can try to use () contain your ?: Operator

string Test(bool @bool) => $"you're {(@bool ? "hired":"fired")} Have a nice day!";

$ - string interpolation
