Regarding the popularity, merit alone is not sufficient. I agree Websharper looks great, and I wanted to use it to develop an open source web app, but I'm in the process of changing my mind. The reason is that there's literally no support for the non-paying customer (their gitter channel is a no man's land), the documentation is good but not complete (eg, some annotations I see in examples are not documented), or if it is complete, it is difficult to find your way to the information (eg some links in the doc can't be opened in another tab because it is handled with javascript), the API doc is unusable (no comment, no example, just the types of the functions are given).

Publishing software under an open source license is not sufficient to have a community grow around it. It requires commitment and efforts. It seems Intellifactory has chosen to focus on their paying customer, which is a choice they absolutely have the right to do. Sadly for open source developers, it makes using their software a hard choice.

I really would have liked it to be otherwise, their software seems to be top notch!
