I wrote a PN extension in Visual Studio 2010 Beta 2 and it compiles fine.
Basically, when I place my compiled DLL in the PN directory and run pn --findexts, it exits with no messages and PN doesn't show my extension in Tools > Options > Extensions. Even if I add my extension to config.xml myself, it still doesn't get loaded.
Any ideas?

Hi David,
The most common cause is that the extension entry point is being name mangled for some reason. If you check the exports for your DLL they should look something like:
C:\Program Files (x86)\Programmer's Notepad> dumpbin /exports pypn.dll
Microsoft (R) COFF/PE Dumper Version 9.00.30729.01
Copyright (C) Microsoft Corporation. All rights reserved.
Dump of file pypn.dll
File Type: DLL
Section contains the following exports for pypn.dll

If you need any more help feel free to mail the project to me or upload somewhere for me to take a look (github, bitbucket etc.).

Also, have you tried building the textutil plugin from http://pnotepad-plugins.googlecode.com/ to see if that works for you from VS2010?
My project is configured virtually the same as the template, demo, PyPN, and textutil projects except that I had to explicitly set the path to the boost includes. The exports aren't being mangled, either. I was able to download textutil, convert it to the VS2010 project format, and build it successfully. However, PN doesn't load it, either.
I think I'll just wait for the RTM version of VS2010 and try again. I've got a separate installation of VS2008 on the same machine that refuses to build anything, so I think the tools are getting mixed up. Better to just start over with a clean slate when the times comes, I think.
Thanks for the help!

It just occurred to me that there's one other question I didn't ask - what version of PN are you trying this with? The textutil extension is built for v2.1, the testing release - it won't load into 2.0.10.
I'm using PN v2.0.10 with SDK v 2.0.9.921.
