This is a quick set of projects to reproduce several issues relates to nanoFramework.ResourceManager and the resource generator. All of these issues are only reproducible when there are multiple resource files in the same application.
It was suggested in Discord that there is perhaps an unenforced requirement of only having a single resource file per project. If this is the case then these could potentially be solved by having the build task detect multiple resource files and throwing a clear error that explains the limitation.
This application will not build as the resource keys from multiple resource files are added to the same dictionary and a duplicate key exception is thrown.

This application fails to load resources that have been assigned positive resource ids when there are multiple resource files. Positive ids work when there is only a single resource file as demonstrated in SingleResourceFile

This application uses the same resource ids as the PositiveResourceIds but demonstrates how the problem does not exist when there is only a single resource file
