What specific section or headline is this issue about?

wsserver.cs in "Put together"

What information was incorrect, unhelpful, or incomplete?

From the following lines: for (ulong i = 0; i < msglen; ++i) decoded[i] = (byte)(bytes[offset + i] ^ masks[i % 4]); I got the error CS0034: Operator '+' is ambiguous on operands of type 'int' and 'ulong'. I fixed the problem by making offset a ulong. I do not know if that is the best solution.

Otherwise, the sample works.

What did you expect to see?

A clean build.

Do you have any supporting links, references, or citations?

Try the build yourself.

Do you have anything more you want to share?

No

Hello! Cast offset to ulong type

[Josh-Cena]

The offset variable should be declared as a ulong in the first place.
