I had to do this today in .NET 2.0. (Visual Studio 2005) Found an example on David Hayden's blog:
Configuration config = ConfigurationManager.
OpenExeConfiguration(ConfigurationUserLevel.None);
ConfigurationSection section =
config.GetSection("connectionStrings");
if (section != null)
{
if (!section.IsReadOnly())
{
section.SectionInformation.ProtectSection
("RsaProtectedConfigurationProvider");
section.SectionInformation.ForceSave = true;
config.Save(ConfigurationSaveMode.Full);
}
}
