I have a managed C# dll that uses an unmanaged C++ dll using DLLImport. All is working great. However, I want to embed that unmanaged DLL inside my managed DLL as explain by Microsoft there: So I added the unmanaged dll file to my managed dll project, set the property to 'Embedded Resource' and modify the DLLImport to something like: [DllImport('Unmanaged Driver.dll, Wrapper Engine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null', CallingConvention = CallingConvention.Winapi)] where 'Wrapper Engine' is the assembly name of my managed DLL 'Unmanaged Driver.dll' is the unmanaged DLL When I run, I get: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) I saw from MSDN and from that's supposed to be possible. I wasn't aware this is possible - I'd guess that the CLR needs to extract the embedded native DLL somewhere (Windows needs to have a file for the DLL to load it - it cannot load an image from raw memory), and wherever it's trying to do that the process does not have permission. Something like might give you a clue if the pronblem is that creating the DLL file is failing. Full Version Hidden Object Games S No Time Limit.

A Windows executable, EXE or DLL, must conform to a file format called the PE file format, which is a derivative of the Microsoft Common Object File Format (COFF). Migrating Native Code to the.NET. Of Managed/Unmanaged Code Interoperability. Directly mixing managed and unmanaged code in the same executable file.

Now that I've been able to read Suzanne Cook's article (the page didn't come up for me before), note that she is not talking about embedding the native DLL as a resource inside the managed DLL, but rather as a linked resource - the native DLL still needs to be its own file in the file system. See, where it says: The resource file is not added to the output file.

This differs from the /resource option which does embed a resource file in the output file. What this seems to do is add metadata to the assembly that causes the native DLL to logically be part of the assembly (even though it's physically a separate file). So things like putting the managed assembly into the GAC will automatically include the native DLL, etc. Mastercraft Ceiling Bicycle Lift Manual more.

How to load unmanaged (native). That our module is native code. (there are not) of embedded resources. Embedding assemblies inside another assembly. Those other two files get bundled in to MyAssembly.dll and are usable in its code. If you embed the file named.
