What happens when this program is compiled and run?

int x = 2.5;
Console.WriteLine(x);

It does not compile

Expecting 2: C# never drops a fraction silently, so putting 2.5 into an int stops the build with error CS0266.
Expecting an error only at run time: the compiler already sees a double going into an int variable, so no program is built and nothing runs.
