General
I am developing a mobile application using the Xamarin framework. The project is quite large and uses several nuget packages.
Environment
- Xamarin.Forms v2.5.0.122203
- Xamarin for VS2015 4.9.0.753
- Visual Studio Professional 2015
- Mono.Android v6
- Target framework Android 6.0 (Marshmallow)
- Minimum Android version 4.4.87 (API 20 - Kit Kat)
Suddenly after installing some packages (I can't remember which one) I get the following error
Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'System.Web, Version=4.0.0.0'
It seems like a package uses System.Web.
So I thought I could just add the reference from here
- C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\vX.X
The project is compiling and starting. But instantly after starting the app on my tablet, it crashes.
Debug output
04-24 10:30:02.924 D/Mono (26732): Assembly Loader probing location: 'System.Web'.
04-24 10:30:02.924 F/monodroid-assembly(26732): Could not load assembly 'System.Web' during startup registration.
04-24 10:30:02.924 F/monodroid-assembly(26732): This might be due to an invalid debug installation.
04-24 10:30:02.924 F/monodroid-assembly(26732): A common cause is to 'adb install' the app directly instead of doing from the IDE.
I don't assume anyone has a clear solution for this. Is there a tool which tells me, what package references System.Web?
Thanks in advance!

The 'HWebbuilder'-packages are custom private packages. They do not contain a reference to System.Web. I doublechecked it.
