Does the indexer really need to lock those files? I don't think we can fix this for 1.0 as this is a little tricky and I think there are other issues/features that would also need to be addressed to support this scenario. We're also only taking small bug fixes at this point as we're locking down for 1.0 so it'll have to wait for 1.1. To fix the immediate issue of locking the files we could switch to reading the file in as a byte array and then loading it that way. Or we could do a shadow-copy type thing where we copy the assembly to another location. But doing so would significantly change how the assembly is getting loaded potentially including what CLR loader context it gets loaded into so it needs to be done carefully. I also think you'd probably want us to re-load the assemblies when you re-build them. And finally we're loading the assemblies into Visual Studio's process and into the default app domain so we could eventually run out of memory if we keep reloading the assemblies. As a workaround could you copy the assemblies to a different path and tell VS about that path? I've opened a feature for this: http://pytools.codeplex.com/workitem/411 which you can vote for. Or if you'd like to contribute a fix you could do that too :) ================================================================================= Yup, that sounds pretty involved. Thanks for the reply and the information. I actually did try copying the assemblies to another path, but as you guessed, I wanted them to be copied (and hopefully re-indexed) automatically on build, and my post-build event would fail just like the build did earlier. Maybe I'll settle for manual copying for now. Thanks for adding the feature request. Learning enough to tackle it myself is, unfortunately, probably beyond the scope of my current project. But thanks for the great tools and everything they already do.
