Introducing .NET 4.0: with Visual Studio 2010

4.6. Monitoring and Profiling

.NET 4.0 introduces a number of enhancements that enable you to monitor, debug, and handle exceptions:

• .NET 4.0 allows you to obtain CPU and memory usage per application domain, which is particularly useful for ASP.NET applications (see Chapter 10).

• It is now possible to access ETW (Event Tracing for Windows) logs from .NET (no information on this is available at the time of writing, however).

• A number of APIs have been (no information on this is available at the time of writing, however) exposed for profiling and debugging purposes.

• No longer must profilers be attached at application startup; they can be added at any point. These profilers have no impact and can be detached at any time.
