I am getting missing method exception in Sitecore while using Glass mapper. This is working in Sitecore 7 project but when I tried to use same in Sitecore 6.6 project it fails. I am not getting that how to find what is the problem in underlying method invocation going on.
I guess this may be due to .net framework version difference in Sitecore 6.6 and Sitecore 7.0
I am using Glass.Mapper.Sc.CastleWindsor nuget package version 3.0.3.7

Also I am not able to find complete source anywhere for Glass mapper.
It's your .NET framework version. Am guessing your Sitecore 7 runs as .NET 4.5 and your 6.6 solution on something lower.
Recent builds of 6.6 (as of atleast 130404) support .NET Framework Version 4.5
