SA1625 - This rule is poorly named.

[simkin2004]

The name of this rule reflects an action that was taken to get the code into a rule-breaking state, not the actual state that is the problem.

The Description of SA1625 is correct...
"The Xml documentation for a C# element contains two or more identical entries"
until the second phrase..
"indicating that the documentation has been copied and pasted."

/// <returns>A configured <see cref="WebApplicationBuilder"/>.</returns>/// <returns>A configured <see cref="WebApplicationBuilder"/>.</returns> public static WebApplicationBuilder

I can think of at least two other ways in the IDE to get into this state: bad merge & bad highlight & delete, neither of which describes the problem.

The -actual- problem is a duplicate tag for the same element, not the action I took to get into the bad state.

I would recommend changing this rule to something like:

ElementDocumentationMustNotBeDuplicated
or
ElementContainsTwoOrMoreIdenticalEntries (which would align with the documentation already provided).
