Solution:

1. Get LuaInterface project files from the server
2. Recomplie lua51.dll and luaInterface.dll on .net 4.0
3. Add new .dll's to your project reference directory

I'll update the projects and attach a release that supports .NET 4

You need to add the <a 
href="http://msdn.microsoft.com/en-us/library/bbx34a2h.aspx">useLegacyV2RuntimeA
ctivationPolicy</a> attribute to your app.config file. I had the same issue 
when upgrading to C# 4 for a managed DX9 class library.

Please fix this and re-release the updated binary. .NET 4.0 has been out for a 
long time now.

Adding that to the app.config doesn't work for me. However, the binaries here 
worked:  
http://www.mdome.org/2011/05/16/luainterface-for-csharp-net-4-custom-build/

Once caveat, I had to make sure that the target cpu for my application was x86 
(I run Win7 64-bit).
