What version of .Net is that WCFD service written in?

1 solution

It happens on any 2.0 and also in .net framework 4.7.2 & 4.5.
I think issue is something else, may be below.
When I tried to browse service url, it went through ssl communication step and then asking for username password. It seems like it needs Authentication before serving. this make sense now why VS studio could not create proxy classes.
