.NET Performance
Description
This three-day instructor-led course provides students with the knowledge and skills to develop high-performance applications with the .NET Framework. Building high-performance applications with the .NET Framework requires deep understanding of .NET memory management (GC), type internals, collection implementation and most importantly - tools for measuring application performance. The course features numerous performance measurement scenarios, optimization tricks, deep focus on .NET internals and high-performance development guidelines.
Intended audience
This course is intended for C# developers with practical experience of at least a year with the .NET framework.
