Edit 2011-12-11: This article is compatible with the final version of Silverlight 5 (5.0.61118.0).
The first posts with questions about 64-bit support in Silverlight 5 already start to show up. The thing is that the 64-bit version of the plug-in is not installed by default when you install the tools. So even though the documentation says Silverlight 5 has 64-bit support, you are still prompted to install Silverlight when you use a 64-bit browser to access a Silverlight application.
The solution to this is to install the 64-bit runtime manually; the installer can be downloaded from here:
… or by using the direct links here:
After the installation, you will see that Silverlight content shows up correctly in e.g. IE9 64-bit.
