i have several winform tools now. publish them on internal website. issue in case smartscreen filter turned on in ie users can't download them. "blocked" error message. if it's turned off fine, smartscreen sure. all files signed verisign certificates , file details filled. so question: ho can make smartscreen trust files, or how can bypass without making users turning off? since internal company tool, should ask company's systems administrators deploy you. it can deployed using group policy, systems management server or whatever management system use. systems administrators have ability enable clickonce, can deploy using clickonce. no doubt have other methods use other internal tools. but short answer is: you should not trying circumvent protections company has put in place. instead, talk them , find way done.
