Auto type casting in condition experssion assignment and etc.

[mojtabakaviani]

by default number is integer, so when assignment to smaller types need casting.
for example:

int a = 5, b = 6;
byte c = (byte)(a > b ? 1 : 0);

but 0,1 in byte range, Roslyn is intelligent and can auto casting.

byte c = a > b ? 1 : 0;

If I understand this request, you are asking for "target typing" to see through "?:" expressions.

[mojtabakaviani]

Yes, "?:" expressions is very good example.

I believe this would be a breaking language change, as the current specification for finding a common type among the operands of ?: and the proposed treatment using target typing could get different results. Since we don't want breaking changes, closing.
