I'm trying to create an absurdly simple shell extension in C++ using Visual Studio 2010, but I can't even seem to get the examples out there to work as a starting point.
I'm using Windows 7 x64.
I've tried this Visual Studio template, but once I get the template to work in VS2010, I have a host of errors that I'm not sure how to fix.
I've tried The Complete Idiot's Guide to Writing Shell Extensions, and once the demo compiles all the right registry settings etc. are created but no context menu appears.
I've looked at this C# COM Interop example, but I've been left confused as to whether it is safe to use C# thanks to this article*, but it looks like I might be OK if I use .NET 4 because it supports in process side-by-side CLR hosting.
- in short: historically two versions of .NET cannot run in the same process, and the way shell extensions work is they inject themselves into a process. So if .NET 3.5 gets injected into a .NET 2 process - bang
So, can I use .NET 4.0 now?
Is there a working, downloadable, VS2010 solution that adds a simple shell extension?
I used to be not so bad with C++ back in the day, but after years of moulding to .NET I'm quite rusty, and as such, fiddling with the details to fix the host of errors I'm getting on the existing examples is proving... fiddly!
I could really do with a clean slate to start with that I can break myself and figure out what I did wrong!
