unresolved external symbol ?.cctor@@$$FYMXXZ

This error is usually related to upgrading Managed C++ project from Visual Studio 2003 to Visual Studio 2005. It is easy to resolve by removing a few options from both the compiler and linker, then recompiling the project. For the compiler remove the /ZI flag (don't confuse with /Zi). In the project properties pages choose "Configuration Properties", then "C/C++", then "Command Line". In the bottom part of the page you'll see "Additional Options". Remove /ZI from there if you have it at all. Next, go to "Linker", then "Command Line". Remove /NOENTRY and /NODEFAULTLIB from there if you have it at all. In all cases make sure you do this for all configurations not just the debug or the release configuration. More details about the context and background are available here.
