I got myself very surprised after I wrote this small code to compare .NET 4.5 and Java 8 performance in my computer: class ArrayTest { public int[][] jagged; public ArrayTest(int width, int height) { Height = height; Width = width; Random rng = new Random(); jagged = new int[width][]; for (int i = 0; i < height; i++) { jagged[i] = new int[width]; for (int j = 0; j < jagged[i][j]; j++) { jagged[i][j] = rng.Next(2048); } } } public int this[int i, int j] { get { return jagged[i][j]; } set { jagged[i][j] = value; } } public void DoMath(ArrayTest a) { for (int i = 0; i < Height; i++) { for (int j

I know that when objects are created in Heap, they also have extra two more fields: Sync Block Index Type Object Pointer So I wonder when Type Object is created in Heap memory and what kind of data it holds? It only represents the metadata of the Type? I haven't been able to find much detail about that. The Type object also contains the bytes that back any static fields on the type as well as a method table with one entry per method defined within the type. Each entry in the method table points to JIT-compiled native code if the method has been executed at least once. The type object is

I was browsing .NET source code and saw this attribute . It says, An attribute that can be attached to JIT Intrinsic methods/properties and according to MSDN : Indicates that a modified method is an intrinsic value for which the just-in-time (JIT) compiler can perform special code generation. This class cannot be inherited. but I had trouble to find how . On what kind of code it performs a special code generation? My main guess is that it mainly uses processor instructions like SIMD, something like Java JIT does . Here is an example . I'm curious about the acceleration it does and I wonder if

Do you know any good book about the workings of the CLR, the .NET Framework and CIL as opposed to any specific .NET language? Regardless of any other books, you will definitely need ECMA-335 standard for a detailed specification of CLR and CIL. With sufficient experience, it may actually be sufficient on its own. Also, "Expert .NET 2.0 IL Assembler" looks like it matches your requirements, though I haven't read it and can't comment on its quality. Amazon description looks promising, though: Topics include managed executable file structure, metadata table structure, Microsoft IL instructions,

I have a project open in Visual Studio (it happens to be Enyim.Caching). This assembly wants to be delay-signed. In fact, it desires so strongly to be delay-signed, that I am unable to force Visual studio to compile it without delay signing. I have unchecked "Delay sign only" and "Sign the assembly" on the Visual Studio project properties box, and rebuilt. The assembly is still marked for delay sign (as shown by sn.exe -v ). I have unloaded the project and verified that the signing is set to false. When reloading the project, the check boxes for "Sign" and "Delay Sign" are checked. I have
