I’m trying to write to the windows registry at HKEY_CURRENT_USER\Software\appname however I keep getting a permissions error when I attempt to write to the key, I have added the following to my assembly:
[assembly: RegistryPermissionAttribute(SecurityAction.RequestMinimum, Write = @'HKEY_CURRENT_USER\\Software')] but this has not resolved the issue, is there something else that I should be doing?
The RegistryPermissionAttribute is part of the Code Access Security aka CAS, this is a permission system which checks the permission you have inside of the .NET framework, these permissions are defined by the security policy. There are 4 security policies:
The first 3 are configured in the configuration screen in the .NET Configuration tool, and the last is configured at runtime.
The reason why I explain this first is because the RegistryPermissionAttribute only checks your .NET permissions, it does not check the Operating System permissions.
You could use the System.Security.AccessControl to check the operating system permissions, but to get the permissions you’ll probably need to either elevate or impersonate.
