I am trying to click on the project and publish it. But what I get is this:
Error 94 An error occurred while signing: Failed to sign
bin\Debug\app.publish\setup.exe. SignTool Error: The signer's certificate is not valid for signing. SignTool Error: An error occurred while attempting to sign: bin\Debug\app.publish\setup.exe CHATT3R
What does it mean?
Click the sign in option and select the checkbox (Sign the Click Once manifests). Go to Security >> select Check Box (Enable Click Once Security Settings). Go to Publish >> select Publishing folder location path and Save. Click "Publish Now" button.
Win Form has been used to develop many applications. Because of its high age (born in 2003), WinForm was officially declared dead by Microsoft in 2014. However, Win Form is still alive and well.
WinForms won't be deprecated until Win32 is ... which could be quite sometime! WPF on the other hand has few direct dependencies on Win32 so could potentially form the basis of a "fresh start" UI layer on a future version of windows.
I had this problem. It turns out the certificate had expired (useful error message - thanks Microsoft)
If you go to the Signing page in the project properties you can see the expiry date, and create a new test certificate if required.
Go to Signing page in the project properties and Uncheck Sign The ClickOnce manifests.
