I don't know how you faced the fact that Reflector is no longer free, but I for one was very-very dissapointed. Now, our favorite JetBrains team comes to rescue with their brand new tool called dotPeek.
Go and get it here.
PS. Five minutes later I found another tool that will compete to take Reflector's place - JustDecompile from Telerik. It is here.
PPS. Also, there is a work being done for Silverlight by Denis Vuyka and there is another OSS tool to compete for our souls - ILSpy.
PPPS. Life is good again.
