Delete c++ librarie

dear developper,

how to propper delete a c++ library from plc-next engineer 2021.9? 

after deleting the library in the library tree (on the right) the plcnext component tree (on the left) is complaining it can not find the library, which makes sense because it is deleted. 

plc-next engineer is raising an error as long as it does not see the library. in other words it can not be deleted.
what is the right procedure?


kind regards nick



Hi Nick,

It's not mentioned in the Change Notes for PLCnext Engineer, but the procedure for removing C++ program instances has changed in PLCnext Engineer version 2021.9.

You will notice that there is a new "PLCnext Components" branch on the project tree. If you double-click on that branch, you will probably see one or more C++ Components from your library. These Components were automatically added when you created a C++ program instance, but they need to be deleted manually if you delete the library containing those components from your project.

I can't even find any reference to this feature in the PLCnext Engineer Help system, so I will raise this as an issue with the developers.
