I have 1 project, which I build into a nuget package and another, in which I have installed this package. I updated the first project and then updated the nuget package in the second project. When I run the second project it still uses the old code, but if I go to the source code of the updated class with F12 I see the new code. If I step into it while debugging I see the old code and the location of the file is C:UsersMariaAppDataLocalTemp.vsdbgsrcfeb7085b11850d86ec767edd1961ad72682d40463f69e4b661f84d513154d2df. I have cleared nuget’s cache, which didn’t help, because this location is has nothing to do with nuget(I think), hence the problem isn’t whit nuget caching. I also tried renaming/deleting the .cs file from said location, and then I can’t step into it while debugging, but it still throws the exception that is fixed in the new version, so it’s obviously still using the old code. I have recently updated VS to the newest version 17.11.3, if that has anything to do with it.
