It appears that there is a requirement when unpacking an .msapp file that the destination folder must be empty of all files, or contain a 'CanvasManifest.json' file (see here). Is there any way to not make this a requirement? I would like to extract the contents of the app at the root folder of an existing Visual Studio project which will always contain at the very least the '.csproj' file. In order to work around this limitation I would need to extract the contents into a sub-folder which would make the project structure not as convenient.
Another suggestion might be to make an exception if the only file in the folder is a project file?
