Tests for old .NET Frameworks about qrcoder HOT 2 CLOSED

Then there's maybe a change in the .NET Framework implementation...

Background:
The idea of the tests was to generate a PNG (because in opposite to JPEG it has lossless compression and the same input Image object should return the same PNG file/bytes every time) and build a hash of the resulting file. Thus it should be ensured, that the QRCode has to look exactly the same to make an positive assumption.

When I wrote the tests the same Image object, saved to PNG file, created byte-wise different files, when running in .NET 3.5/.NET 4.X vs all other framework versions. Back then I checked the files in a hex editor and saw that the PNG headers, written bei .NET differed in dependency to the used framework version.
Different PNG file headers resulted in different checksums. That's why I added the compiler flags/branches in the test case.

If it returns the same checksum now, then there must have been a patch in the framework.

Thanks, that is exactly what I thought.

Well, because I had to download .NET Framework 4.5 additionaly, maybe there is something wrong on my side.

Thanks for the answer and have a great day.
