The signer's certificate is not valid for signing

Question

While debugging in Visual Studio I am getting this error

The signer's certificate is not valid for signing, An error occured while attempting to sign:sharepoint_link.dll,The command
""C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\signtool.exe" sign /f
"C:\Users\Administrator\Documents\GitHub\SPLink2010\SharePoint_Link\ITOPIA_certificate2.p12"/p $h0pp1ng /t "http://tsa.starfieldtech.com" "SharePoint_Link.dll""
exited with code 1

I have created a new test certificate and imported it through certificate import wizard but I'm still getting this error. I also have removed the old temporary certificate using certmgr.exe but in vain, I am still getting this error.

Answer 1

It's simple; just follow the following steps:

1. Right click on Project in Solution Explorer on right side panel, and choose Properties from the context menu. Remember to right click on Main Project, not solution.

2. A window will open, then click on Signing tab.

3. There you can see a button Create Test Certificate, click on it and it will ask for password just leave it empty and there you are done.
