[Feature] Update azure-pipelines.yml (version, build and release)

[Hofknecht]

We created a dotnetframework.yml, this builds and sends mail when build fails (was replaced by azure-pipelines.yml)

TODO:

• Version and Release process, e.g. release to project website
• here a release process https://medium.com/@two06/building-tooling-with-github-actions-59401648e61d
• related to fixcop, should we set severity level to error, so that *.yml throws a fail mail?
• i think we decided against but think again if versioning ok, we set it still manaully https://stackoverflow.com/questions/3387108/details-of-assembly-version/3387167#3387167

with that tutorial https://www.kenc.dk/post/2019/9/23/creating-github-release-using-azure-devops-pipeline we reached that it was synced to git tags

todo: adjust version, move to release, build&zip and release with the tag
