Hi Juergen, What errors are you getting?
thanks for your reply.
Error: This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them. For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is ..\packages\System.Data.SQLite.Core.188.8.131.52\build\net46\System.Data.SQLite.Core.targets. PrintStation C:\Source\v2.14.1989\print_station\Source\PrintStation.csproj 248
Every reference (System.Core, System.data,..) can not be found!
Right click on Solution, Restore Packages don't solve the problem.
OK, I can create a new project, import all source code, adding all needed references. But I'm sure there must be a better solution
