リンク SDK アセンブリを xamarin studio でのみ使用すると例外が発生し、dont link を使用すると例外は発生しません。この問題は、私が使用しているサード パーティの dll (ビデオ ストリーミング サービスの API) の一部であることがわかりました。リンカーは、この dll で使用されるメソッドの一部を削除していると思います。一部のライブラリのリンクをスキップすることは可能ですか?また、このスタックトレースからどれを確認することは可能ですか?

どんな助けでも大歓迎です。
更新: stuart が提案したように (stuart に感謝)、LinkerPleaseInclude ファイルを次のように追加しました: しかし、それでも例外が発生します。
class LinkerIncludePlease
{
private void DelegateCombine(Delegate a, Delegate b)
{
var d = Delegate.Combine(a,b);
}
private void DelegateCombine(params Delegate[] delegates)
{
var d = Delegate.Combine(delegates);
}
private void DelegateCombine()
{
var d = Delegate.Combine();
}
}
私の考えでは、それはスタックトレースに関連するものでなければなりませんでした

しかし、それはうまくいかないようです-何が取り除かれているかを見つけるための指針はありますか?
