When analysing the performance of different String manipulation methods, String.Concat came out drastically slower than the same code compiled for .NET 3.5Please see this article I wrote: http://www.daniweb.com/software-development/csharp/code/448050/performance-of-string-operationsIt seems to be the way that the IL is generated. It is subtly different to the same code compiled for .NET 3.5. Why does the same level of optimisation no longer apply in 4.5?
