Commented Issue: FileLoadException - Could not load file or assembly 'OpenRiaServices.DomainServices.Client.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies [98]

The commit: ddcb0ea2 made by danneesset <daniel.svensson@hotmail.se>at 8/12/2016 12:54:52 PM introduced FileLoadException in Silverlight version of OpenRiaServices.DomainServices.Client. The root cause is the change of AssemblyVersion to 4.0.0.0 (from 2.0.5.0). In the effect most probably the following code fails:

OpenRiaServices.DomainServices.Client.Data.DefaultDomainClientFactory:

```
/// <summary>
/// Initializes a new instance of the <see cref="DefaultDomainClientFactory"/> class.
/// </summary>
public DefaultDomainClientFactory()
{
// Look for the WebDomainClient in an assembly with the same version and with same signing key as this assembly
var webDomainClientName = "OpenRiaServices.DomainServices.Client.WebDomainClient`1, "
+ TypeUtility.GetAssembly(typeof(DomainClient)).FullName.Replace("OpenRiaServices.DomainServices.Client", "OpenRiaServices.DomainServices.Client.Web");
_webDomainClientType = Type.GetType(webDomainClientName); // Exception here
}
```

The full stack trace is in here:

Comments: Thank you for reporting the Issue, I will update the version of the Silverlight web assembly in order to fix the issue. You can find the latest non-released code from https://ci.appveyor.com/project/Daniel-Svensson/openriaserviecs/branch/master/job/ojqnyexfc1ot4lxf if you want to test it. It should be possible to just replace the web assembly with the latest build until the next release on nuget
