Description Jonathan Pryor 2015-03-17 17:14:32 UTC
Suppose you have a custom attribute:

    [AttributeUsage (AttributeTargets.Method)]
    public class SomethingAttribute : Attribute {
        public SomethingAttribute (string value)

...which is used somewhere:

    class Example {
        [Something ("value")]
        public void Foo ()

Then you decide that SomethingAttribute is a terrible name, and Refactor > Rename the type to "UghAttribute".

After using the IDE's Rename support, the type is properly renamed:

    [AttributeUsage (AttributeTargets.Method)]
    public class UghAttribute : Attribute {
        public UghAttribute (string value)

Unfortunately all custom attribute *use* is "screwed up":

    class Example {
        public void Foo ()

The original [Something ("value")] becomes [UghAttributeUghAttribute]; the actual parameter values are lost.
