We have checked the reported
issue with Blink ClickOnce sample on our end and able to reproduce the Blink
files missing exception on our end. The reported exception occurs due to that
the required Blink binaries are not available in that ClickOnce app location.
To overcome this exception, we need to include the BlinkBinaries folder files
in the WinForms project. We have attached the runnable ClickOnce sample for
your reference, please find the sample link below,
Sample: Sample: https://www.syncfusion.com/downloads/support/directtrac/general/ze/WindowsFormsClickOnce1572287648
Please set the Copy to Output
Directory as “Copy always” and Build Action as “Content”
to all the Blink Binaries inner and sub folder files,
Please make sure the Blink
Binaries folder files are included in the ClickOnce app location after
publishing the project, refer the below screenshot,
Please try the above solution on your end and
let us know the result.
