with above policy , I am able to upload the file by sending it as binary in POST Call . however, I want to upload it as multipart/form-data within File key

I need help in parsing the multipart form-data body File key. as context.Request.File is not supported in APIM. dsadsadsadasdsadnmslakjfd;s;fk;dks;lfkl;dks;kf;ldsk;lfds;fdljfldjslaf
