I've met a very strange exception in my application. A public action
method 'X' was not found on controller 'Y'. After googling for a
while I found that it can be when your action is marked with HttpPost
or HttpGet attribute, but http method of you request doesn't fit to
it. In my case my method action was marked as HttpPost and I was
pretty sure that I use POST method in my request. Then I used
debugger and found that HttpContext.Request.HttpMethod is equals to
"GET". It was really strange. It actually means that
something changes my request. I went to Web.config and found
something really interesting – UrlRewrite module and bunch of
rules. My request was affected by one of them, that led to redirect,
and because of redirect it changed original POST http method to GET.
