How do you debug/fix a "Common Language Runtime detected an invalid program" error? What exactly does it mean anyway? I have a C# MVC 2 web app that can deployed to two websites that reside on the same IIS 7.5 webserver (x64). One is the live site (deployed using Release configuration), the second is the beta site (deployed using a new Beta configuration created just for this project). The two websites are: Default Website/my_app Beta/my_app On the beta site when selecting a paged list of purchase orders, it throws the "detected an invalid program" exception. The exact same code when run on

The question seems like a dirty hack you should not do but let me explain first. The ultimate goal is to have method local statics like in C++. void Func() { static methodLocalObject = new ExpensiveThing(); // use methodlocal Object } What has this to do with the instruction pointer? I want to cache data depending on my caller. To make this fast I walk back in the stack to get the address of my caller and use this as unique key for a dictionary to store the data. That would allow to create a reflection based tracer which does not use Reflection every time to get the name of the current method

I have a minidump crashed from a .NET application. Is there any way to know the CLR version (e.g. version of mscorwks.dll) of the fault machine (which generates the crash dump) using either Windbg or some other tool? In WinDbg: the easiest way is to use the !eeversion command, but if you want additional info you can use the lm command with the v verbose option for the runtime module mscorwks . If you're on .NET 4 the runtime is called clr , so in that case you need to change the command accordingly. 0:026> lm vm mscorwks start end module name 79e70000 7a3ff000 mscorwks T (no symbols) Loaded

I have a Visual Studio project that contains files with managed code and files with unmanaged code. The project has the CLR support, but when I add a file where I do not need .NET I simply turn off the /crl option with a right-click on the file: I added a class that has to contain unmanaged code and use std::mutex. // Foo.h class Foo { std::mutex m; } I got the following error after compiling: error C1189: #error : is not supported when compiling with /clr or /clr:pure. The problem is that I do not have the option to turn off the clr for header files (.h), since this is the window when i right

int and object have a parameterless constructor. Why not string ? Greg Update: To provide more information for you. You don't have an empty Constructor with a string , however you do have String.Empty . The reason is because a string is an immutable object every instance of a string you modify is actually creating a new string in memory. For instance: string name = ""; though it is an empty string it will still hold around twenty bytes . Where the string.Empty will only hold around four or eight bytes . So though they mean the same thing, one is more efficient than the other. However I believe
