I have a solution with 23 applications. When I add a new app to the solution by importing a .txa file I can't build or rebuild the solution. When I click Build/Rebuild, rather than compile each app in the solution the Build/Rebuild output just says "Build Started, Build Finished Successfully" and my new app is never compiled. There must be a flag somewhere in the .sln file that is preventing the Build or Rebuild from doing it's thing. If I delete the solution and recreate it, the Build/Rebuild solution works fine. Anyone have any ideas on how I can resolve this without deleting and recreating my solution? ---

Edit your solution file with Notepad++ and try to see whether the app you have added is added to the solution or not ---

Hey there Ken, I get the same behaviour. It was working yesterday. Today after removing and re-adding some apps from (fixed) txa, it misbehaves. I’ve exited C11 and fired it up again without a change. Did you figure out what the issue was or a workaround? Cheers, Andrew. ---

Hello, I’m having the same problem. Did you find a solution to this? I started my own thread here before I found this one.

I may have found my issue, not sure if works for anyone else. In another post on this forum, for something similar, it was mentioned that an application in the solution may be missing, invalid, wrong something like that. I couldn’t find it when I looked and everything seemed OK. That is until I started playing around with MSBuild. MSBuild.exe with a .msbuild XML file referencing the .cwproj files didn’t complain and seemed to work quite happily. When I tested using the .sln file, then Clarion threw up an error for an invalid GUID, an application that it ‘required’ but wasn’t listed in the solution. I removed the invalid references from the .sln file and now it generates and/or builds from the IDE. Hope this helps some-one. ---

Thanks for the update. In my case I resolved it by creating a new Solution and adding back in all the apps: [https://clarionhub.com/t/clarion-11-unconditional-generation-doesnt-create-new-exe-dlls-for-unchanged-apps/7576/46?u=choreboy](https://clarionhub.com/t/clarion-11-unconditional-generation-doesnt-create-new-exe-dlls-for-unchanged-apps/7576/46) But it’s possible your solution may have worked for me as well. I also make sure I delete all CLW files if I’ve made changes to the Dictionary to ensure everything is up to date.
