As it says, It cant load some of the .NET assemblies. Are you sure you have .NET 3.5 properly installed on that system? – codingbunny
I have .NET 4 installed. but this talks about 3.5.. or do you think my .net 4 install is bad? – ZVenue
.NET 4 isnt the same as 3.5, the version is checked with strong typed assemblies – codingbunny

Make sure thatn .Net Framework 3.5.0.0 is installed in your system. In addition, does your builds have been configured to run on a remote agent? If yes, you should have it installed on all the agents that build .net projects.
