Update to AutoMapper 7.0.0 causes exceptions
See original GitHub issueMapping that works as expected in 6.2.2 and earlier fails with a MissingMethodException in 7.0.0
AutoMapper.AutoMapperMappingException

I have tried to determine the cause but have been unable to do so.
My mapping looks like this:
CreateMap<UpdateViewModel, Model>(MemberList.Source)
.ForSourceMember(x => x.LastName, opt => opt.Ignore())
....
where I have ignored every single source member (including the one that shows up as PropertyMap in the exception - it happens to be a collection like many other properties in my code that are succesfully mapping) and still get it - despite every single member being set to ignore.
This is the only mapping - of dozens - that is causing a problem, and again there is no issue before upgrading to version 7.0.0
I had originally opened this issue in Automapper https://github.com/AutoMapper/AutoMapper/issues/2666 but issue was closed and it was recommended it be opened here instead
Perhaps this is covered by https://github.com/AutoMapper/AutoMapper.Collection/issues/88?

Try the MyGet for the 7.0.0 fix. Just use Automapper.Collections and allow pre-releases
When did you plan to release the new version?
