Thinking back over my managed BA development I hit this problem several times, always do to some issue in my managed BA code, but I do not recall a specific cause. I think I used ProcessExplorer to watch which file it was trying to load at the point of the problem. ILSpy was also helpful in sorting out namespace conflicts, which was a problem when I tried to add a resource dictionary (which conflicted with the name of a resource in the BA host dll, which is what loads your managed BA).
I would not try to take a peice of the wix source as you described, rather follow the process detailed here <http://wixtoolset.org/development/> to build the wix source. It can be a challenge to get all of the tools lined up to build the wix source, or it may go very smooth for you. Once you do that then use the proces here <http://wixtoolset.org/documentation/manual/v3/msbuild/daily_builds.html> to compile your project against your local debug build. (I also ran into issues taking this approach, as I had to carefully edit my wixproj files to set properties to the wix SDK locations to find extension.) In general, I do not build against a local build of wix to debug my managed code and you probably don't need to do the the above either. (I use the local build and WixStdBA to debug wix behavior.) I would first build all projects against the RTM (I use the Release Configuration). Then in VS open the properties for the managed BA project and define Debug and Trace. Then set the Debug path to point at your bundle exe. Add System.Diagnostics.Debugger.Launch(); to the assembly's Run(), and compile the mba. Compile the bundle.exe (rebuild of just the bundle.exe). Right-click on the mba project and select debug. I hope some of the comments are helpful. I am sure that there are other approaches. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Problems-with-debugging-the-BootstrapperCore-source-files-tp7599236p7599271.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
