This is an old application and I have been tasked with building an azure pipeline. We are using VS 2019 and upgraded the application to .net framework 4.6.1.
Build pipeline is failing with this error: Error ASPPARSE: Could not load file or assembly 'System.web.mobile' or one of its dependencies. The system cannot find the file specified.
Application builds and runs fine locally. Once I try to build an azure build pipeline I get error above.
From searching online it seems system.web.mobile is no longer used in 4.6.1. Is there a valid replacement or work around?
The problem was that the "System.Web.Mobile.dll" on your local machine, make sure restore this assembly in your pipeline.
If you don't use this assembly, as @Dai mentioned, you can remove it in your web.config files and .csproj files.
