问题 As part of my project I need to use some Unamanged code dlls in Silverlight. If I wrap these unmanaged dlls in a C# dll will I be able to access the native dlls from silverlight. I use Visual Studio 2010 and Silverlight 4.0 回答1: With Silverlight 4, you can call out to COM objects installed on the local machine. However to do this the user has to choose to allow the Silverlight App full access to their machine. In addition the COM object needs to already be installed on the machine. Therefore

问题 Apparently the implementation of Assembly.Load() in Silverlight needs a full/strong name. E.g. this works: Assembly.Load("MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=..."); while this will fail even if MyAssembly is already loaded: Assembly.Load("MyAssembly"); Is there a workaround so that it's possible to use the simple name? 回答1: As far as I know, there isn't a way to work around this in Silverlight without using the full name.

问题 I have a hopefully trivial question. Currently, my company works with a rather obscure language (SyngergyDE) and we need to call a SilverLight application inside our product. Unfortunately, this obscure 3rd party language only (currently) supports the opening of WPF screens. So with that said, I thought I'd develop a small WPF user control that contains a "WebBrowser" control and navigate to the silverlight application's URI. This works fine, and I'm able to see the SL application. Here is my
