Answer 1

I assume your deploying to another machine/server. In that case you need to install team explorer on the server, its the supported way to get the TFS Client object model installed.

Hi I am deploying to my local IIS, are there .dlls that need to be registered in my local GAC?

Answer 3

I was able to resolve this issue by setting the web site application pool property 'Enable 32 bit applications' to true and setting the platform target in the project build properties to x86
