I have a problem with building wixproj under Visual Studio.
What I have done:
- added my preprocessor extension as separate project (wile reading this post)
- added my extension method invocation in Product.wxs file
First compilation works perfectly. I see changes made in Product.wxs. Things are going wrong while building second, third, fourth time and so on.
This is what I get:
"Unable to copy file "obj\x86\Release\WixStringFormattingExtension.dll" to "bin\Release\WixStringFormattingExtension.dll". The process cannot access the file 'bin\Release\WixStringFormattingExtension.dll' because it is being used by another process."
Restarting Visual Studio helps ... but only for first compilation. It seems like something (light.exe candle.exe devenv.exe) is not releasing files.
This sounds like a bug report instead of a question... That said to confirm your suspicion you could always use Process Explorer to figure out what process is holding a handle to your files. To do that, run it, hit Ctrl+F, and type the name of your file: WixStringFormattingExtension.dll
