Do not use SPWeb.Properties property

SPWeb.Properties is a StringDictionary and doesn't support casing for keys/values (everything gets converted to lowercase). Instead use SPWeb.AllProperties. SPWeb.AllProperties is a Hashtable and supports additional types of data.

CheckId SPC010214
TypeName DoNotUseSPWebProperties
Severity CriticalWarning
Type Assembly

Use SPWeb.AllProperties instead of SPWeb.Properties.
Bad Practice

{
  web.Properties[key] = value;
}

Good Practice
void SetProperty(SPWeb web, string key, string value)
{
  web.AllProperties[key] = value;
}
