  <p>I have downloaded probably like ten times the dot net SDKs and frameworks and it just doesn't work.
  There is like 1 million possible sources for these problems and I just need some help, please. I have been trying to solve this for days now and I just can't, I would extremely appreciate it if someone could help me out.</p>
