Is C# part of the problem?

With Microsoft's introduction of the .NET platform and languages, including its bias towards distributed application components, performance analysis and performance tuning have become substantially more important for today's development efforts. Individual assemblies and Web services that seem to offer adequate performance when unit tested perform unacceptably when integrated as a single application.

One of the biggest, yet largely unexplored, areas of .NET performance concerns the so-called "interop" – the interoperation of managed and unmanaged code in the same application. In most cases, this involves new .NET code calling native code components. However, it's also possible for native applications to call .NET components, although by its nature this is likely to be much less popular.

At this point, many developers don't understand the performance implications of interop. Moreover, they aren't necessarily even cognisant of when their application is performing interop, and what they can do to resolve such problems. In some cases, interop is performed by the .NET Framework, and most developers think it can't be helped. For example, Figure 1 shows the negative performance implications of a line of code that calls into native code indirectly through its children.
