Try to build and nothing happen

hi,

i install visual studio 2017 (The latest version) and after i install monogame (The latest version).
in visual studio i create monogame project and after i open Content.mgcb and load file (png and more) and click on build or rebuild and nothing happen. i tried to reinstall but still the same problem and I also tried another computer and the same problem remains.
Why is this happening and how can it be fixed?

both computers i used in windows 10.

thank

When you say build or rebuild are you referring to the pipleine? Have you saved the pipeline project? Have you checked the folders in explorer to see if they are there. Have you tried running the project in visual studios? If it’s not working you should see some message unless you have untick what to display in the output
