This worked for me vb2019. I copied my source project folder. I then pasted the project, and renamed the the folder to whatever. In order to break the ties back to the source project folder, I temporarily renamed the source folder. I opened my destination project. The paths to the forms and modules were re-discovered in the local folder. I went through all my forms and modules to make sure they were working. I ran the project. I closed the project. I renamed the source project folder back to is't original name. I can open both projects at the same time without errors.

close your visual studio process. Then, find your project and copy the project folder But, first make a Sub-folder Named Projects inside of your visual studio 2017 folder in documents. Next, paste the project folder inside of your visual studio 2017 Project folder not the main visual studio 2017 folder it should go into the Sub-folder called Projects. Next, restart Visual studio 2017 Then, choose Open project Solution Then, find your project you pasted in your visual studio 2017 Projects folder Then clean the Project and rebuild it , It, should build and compile just fine. Hope, this Helped out anybody else. Not to sure why Microsoft thought building your projects in a path where it needs write permissions is beyond me.
