Student Technology Conference 2005Ziele von Visual Studio 2005
• Zwischenschritt auf dem Weg zu WinFx/Longhorn
• Top-Customer Issues• Produktivität
– Weniger Codezeilen bis zum Ergebnis
• Performance• Dinge, die bisher nicht möglich waren
– Neue Managed-Klassen– .NET Code in der Datenbankschicht

Student Technology Conference 2005RAD Debugging
• Edit and Continue: Code zur Laufzeit verändernErlaubte Änderungen – Beispiele:– Hinzufügen von privaten Felder zu einer Klasse– Hinzufügen von privaten, nicht-virtuellen Methoden zu einer
Klasse– Verändern des Inhalts einer Methode (auch während des
“Stepping”)Verbotene Änderungen – Beispiele:– Entfernen von Feldern/Methoden– Bearbeiten von generischen Klassen (Generics)– Die Serialisierung erkennt neue Felder nicht.
• Display-Attribute für ein komfortableres Debuggen

Student Technology Conference 2005Performance
• Zielsetzungen– Langfristig: Performance der CLR ähnlich zu nativem Code– Reduzieren des Overheads von zusätzlichen verwalteten
Prozessen– Verringern der Startzeit und des Arbeitsspeicherbedarfs
• NGen– Kompiliert IL-Code in nativen Code, speichert Ergebnis auf
Platte– Vorteile: Rekompilierung des IL nach nativen Code
unnötig, somit schnellerer Programmstart– VS 2005: Wesentliche Reduktion des privaten, nicht
gemeinsam verwendeten Arbeitsspeicherbedarfs.– OS: ‘Kein-JIT-Plan, jeglicher managed Code wird ge-NGen-
