Hi!

I have the following problem: When I open the DotNetNuke.sln and click Debug, it all works OK. Then I stop debug AND then, when I try to run it again, I get:
Unable to write to output file 'C:\Documents and Settings\...\VSWebCache\PETRO\DotNetNuke\obj\Debug\DotNetNuke.dll': System Error &H80070020&

The file DotNetNuke.dll gets locked (not buy aspnet_wp.exe) by Visual Studio, I guess because Modules/Projects like for example "DotNetNuke.Announcements" hold a reference to it. What must I do to avoid closing the VS and open it again. I already tried with "trick" with setting a reference attribute "Copy Local" of DotNetNuke.dll in Announcements-Project to False. It does not really help. What do you do, when you try to run things?

Thank you for ALLL suggestions that you might have! Might be that I just have to make my own solution file and include the projects that I actually need and may be it will all work normally?

I had the same problem pop up today. The only way I was unable to unlock the file was a system reboot.

Here is a much more simple way to develop modules.  It avoids the the locking issue and loads your project faster.
