Could not load file or assembly \'Microsoft.VisualStudio.Web.PageInspector.Loader, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a\' or one of its depen
Our project had (incorrectly) reference to the PageInspector.Loader.dll in the GAC for a long time:
..\..\..\..\..\..\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.VisualStudio.Web.PageInspector.Loader\v4.0_1.0.0.0__b03f5f7f11d50a3a\Microsoft.VisualStudio.Web.PageInspector.Loader.dll
It worked for some time, but recently deployment to Azure caused the error "Can not find compilation library location for package Microsoft.VisualStudio.Web.PageInspector.Loader".
We found and deleted the reference from .csproj file and the problem was fixed.
