Based on your other posts I am going to assume you are working with a SL SketchFlow project.
Here are the simple manual process instructions: http://msdn.microsoft.com/en-us/library/dd185521%28Expression.30%29.aspx
If you want automated deployment, like you suggested in the first post, you will need to add a web project, such as an asp.net web application project. In the properties for that project you can set it up to host your SL app. That web project will have the publish options you are looking for.
Blend does not support publishing in the same way the VS does. SketchFlow projects do have a menu option under File -> Package SketchFlow project that will give you easy access to the built assemblies for manual deployment. But if you want to do any automated publishing/packaging, you will need to open the solution in Visual Studio.
