System.IO.FileLoadException: Could not load file or assembly Esri.ArcGISRuntime

In our Windows release builds (but not when running from Visual Studio) our application runs into an exception initializing the ScaleLine control. The ScaleLine is used inside a WPF class library (EsriMapControl) called by another WPF library (CadMap) which is launched from a WinForms application (CAD_APP). This doesn’t seem to occur in another application which is WPF and calls these two libraries.

It seems like the ScaleLine is trying to load runtime 100.4 but EsriMapControl, CadMap, and CAD_APP all have assembly redirects in their app.config for ArcgisRuntime:

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <dependentAssembly>
        <assemblyIdentity name="Esri.ArcGISRuntime" publicKeyToken="8fc3cc631e44ad86" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-100.5.0.0" newVersion="100.5.0.0" />
    </dependentAssembly>
</assemblyBinding>

The references to Esri.ArcGISRuntime and Esri.ArcGISRuntime.Toolkit have ‘specific version’ set to False.

Because of that I was expecting that the ScaleLine would redirect to runtime 100.5 which is what we have installed in the application. I did notice that Esri.ArcGISRuntime is strong named and Esri.ArcGISRuntime.Toolkit is not. Could that be related?

Here is the full stacktrace:

@dotMorten I made a small sample but it doesn’t experience the problem. Unfortunately I can’t reproduce this outside our application. I’ll close this but thanks for the help 👍

I was able to resolve this for now by intercepting the failed assembly resolve and loading the correct runtime version:

AppDomain.CurrentDomain.AssemblyResolve += CurrentDomain_AssemblyResolve;

private Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
{
	Assembly result = null;
	var resolvingAssembly = new AssemblyName(args.Name);

	if (resolvingAssembly.Name == "Esri.ArcGISRuntime")
	{
		//Grab the installed ArcGISRuntime by grabbing the assembly from one of the Runtime's classes
		var installedAssembly = Assembly.GetAssembly(typeof(GraphicsOverlay));
		var installedRuntime = new AssemblyName(installedAssembly.FullName);

		//If we're trying to load something different from the installed version override that
		if (resolvingAssembly.Version != installedRuntime.Version)
		{
			result = installedAssembly;
		}
	}

	return result;
}
