I have project which needs 'sign assembly' set to true while building/running. Operating system - windows 11
Installed certificate pfx with following command
-i "certificate pfx file name with related file path" "container ID"
After executing this command, message appears => "keypair installed in to <container ID>"
After successful installation of certificate keypair, When tried building project -- Build fails with below error ->
"Error signing output with public key from container 'container ID' -- Keyset does not exist (Exception from HRESULT: 0x80090016) "
Please note, This was working fine with my earlier environment with "windows 10" operating system
Not sure if windows 11 needs some additional privileges or permissions so that visual studio can access key container ?

Hello, have you tried to run VS as administrator?
Please try the following command to install key pair and rebuild project:
sn.exe -i <pfx_file> <container_ID>
You can create a new key file to try again.
