F # metadata assembly not updated in visual studio

This is a possible bug in Visual Studio 2015 (and possibly earlier versions?), Just want to check it out here first because I didn't find any similar issues when searching in it.

I have a solution with a C # console app and an F # library that is used by the console app.

In the F # library, I have defined a class with some members and change the members. Although the Intellisense in the C # editor correctly reflects changes in the F # library, the F # assembly metadata is not updated. I tried to clean, rebuild, add assembly reference again, but the only solution is to reopen the solution or restart visual studio.

What's wrong here?
