May be i'm asking the right question.
I found the SimpleDialogCustomizer project, it "help" us the users to develop our own customizers. I edited the customizer code using Visual Studio Community 2017, i remove everything and keep the label1 element.
The first edition i did was deleting one of the images of the customizer, then pressed Build ans Attach customizer and the customizer no longer showed the image, so it was "successfull".
After that i deleted all the other elements on the customizer (kept the label1) and couldn't get the customizer updated on Creator.
I need the button Build and Attach customizer to be available, that's the only way i saw the customizer being updated, may be the old customizer is cached, the design changes i did on VS are not being reflected on the customizer after build.
For reference, this is the button i need to enable:
The project is attached.
You can try deleting the precompiled Component customizer assembly (named _project_.dll - SimpleDialogCustomizer.dll) from the project (but not from disk -- it is open, and the delete from disk will fail).
Refer component_author_guide "8.2 Precompiled Component Customizers"
Thanks for the reply Jobin,
I tried removing the dll from the project but i was getting the same errors.
After that i copied and pasted the project on the same workspace, i got this messages:
Building customizer for project 'SimpleDialogCustomizer_Copy_01'
Customizer build for 'SimpleDialogCustomizer_Copy_01' succeeded
And the customizer is updated with my changes , then i can make more changes and build the customizer with success, the customizer is updated.
I will try this with another toy project and see if i can get it working.
