top_level_cycle

The type of '{0}' can't be inferred because it depends on itself through the cycle: {1}.

The analyzer produces this diagnostic when a top-level variable has no type annotation and the variable's initializer refers to the variable, either directly or indirectly.

The following code produces this diagnostic because the variables x and y are defined in terms of each other, and neither has an explicit type, so the type of the other can't be inferred:

var x = y;
var y = x;

If the two variables don't need to refer to each other, then break the cycle:

var x = 0;
var y = x;

If the two variables need to refer to each other, then give at least one of them an explicit type:

int x = y;
var y = x;
