Usage of _ in methods arguments raises SA1313

Usage of _ in method arguments raises SA1313.

Example:

public override void Foo( int arg, int _ )
{
...
}

Can you please make an exception to SA1313, to support ‘_’ in method arguments?

Closing this one as won’t fix. The recommended solution for method signatures when a parameter is intentionally not used is:

1. Give the parameter a meaningful name. This should match the original definition when applicable (see #1949).
2. Assign the parameter to a discard at the start of the method to clearly indicate to the reader that the parameter is intentionally unused.

For example:

public void Method(T value)
{
  _ = value;
}

Currently IDE0060 suggests that we do in fact rename unused parameters to _:

IDE0060 Remove unused parameter ‘sender’ if it is not part of a shipped public Avoid unused parameters in your code. If the parameter cannot be removed, then change its name so it starts with an underscore and is optionally followed by an integer, such as ‘_’, ‘_1’, ‘_2’, etc. These are treated as special discard symbol names.

However, if we follow that advice, given by the IDE, then we run into this issue. That doesn’t seem like a good thing to Won’t Fix
