[hot_reload] Mono should ignore Param table row updates #56574
Description
Roslyn will emit these for changes like this:
Old code:
public class MethodBody1 {
public static string StaticMethod1 () {
Func <string,string> fn = static (s) => s + "G";
return fn ("OLD STRIN");
}
}
New code:
public class MethodBody1 {
public static string StaticMethod1 () {
Func <string,string> fn = static (s) => s + "G";
return fn ("NEW STRIN");
}
}
Roslyn will emit a param update for 's' even though nothing about the parameter has changed.
(Note that to get a clean delta it's necessary to use hotreload-utils that includes dotnet/hotreload-utils#65, otherwise the delta will be bloated with unnecessary field and method additions for the (unchanged) lambda).
This is part of #44806

The issue description is misleading. Roslyn generates these Param table updates for normal methods, too. Not just for lambdas.
In this case, too Roslyn emits a Param update for
builder.
