I've build a little C# project to try to implement SHA256 myself and tested it with test vectors from set 1 fromhttps://www.cosic.esat.kuleuven.be/nessie/testvectors/hash/sha/Sha-2-256.unverified.test-vectors
I used the pseudo code from http://en.wikipedia.org/wiki/SHA-2
Vector 5 and 6 fails for my program with the following output :
Test failed for string : abcdbcdecdefdefgefghfghighijhijkijkljklmklmnlmnomnopnopq

Expected hash is the hash on the website with tests, result is my own calculated hash, .net version is the hash calculated with .net's System.Security.Cryptography.SHA256.
I can find many websites that just tell me the same thing, my hash is wrong.
I've tried to find it with debugging but I really have no clue where to look since the other 7 tests run just fine.
Can anyone supply me with the w[0..63] values and the a/b/c/d/e/f/g/h values for each of the 64 loops?
