Xamarin PureSocketCluster Multiple Assemblies












1














After adding the Package PureSocketCluster version 3.1.0 to my Xamarin project, I get the following error when compiling:




.../Projects/HelloWorld/HelloWorld.iOS/CSC: Error CS1703:
Multiple assemblies with equivalent identity have been imported: '.../.nuget/packages/system.reflection.emit/4.3.0/ref/netstandard1.1/System.Reflection.Emit.dll'
and
'/Library/Frameworks/Xamarin.iOS.framework/Versions/Current/lib/mono/Xamarin.iOS/Facades/System.Reflection.Emit.dll'.
Remove one of the duplicate references. (CS1703) (HelloWorld.iOS)


During the installation, I observed the following warnings:




Detected package downgrade: Xamarin.Forms from 3.4.0.1008975 to 3.1.0.697729. Reference the package directly from the project to select a different version.
HelloWorld.iOS (>= 1.0.0) -> HelloWorld (>= 1.0.0) -> Xamarin.Forms (>= 3.4.0.1008975)
HelloWorld.iOS (>= 1.0.0) -> Xamarin.Forms (>= 3.1.0.697729)


It's a very basic Hello World project, I just wanted to check if the communication with my socketcluster based websocket works in general.

I am using Visual Studio 2017 for Mac 7.6.11.
I'm fairly new to VS, so please don't kill me, if I made a stupid beginner mistake.

          Of course you need to make sure the nuget package has been added to the iOS package first.
          Here is a similar issue that you can refer.

          • I found that similar issue, but somehow it doesn't work for me. I added the package System.Reflection.Emit to the iOS project. Then I unloaded the project by right click > unload. Then I edited the project file by right click > Tools > Edit File. I added the PackageReference to an already present ItemGroupnode under <Project><PropertyGroup>. I reloaded the project and cleaned it, then I built it, which results in the same error.
