    Hello Everyone,

    The SOA HelloWorldR2 samples (in the sp2 sdk) have projects that reference .net 4, however when I try to run these samples I get an error "Could not load file or assembly 'file:///C:\ServicesR2\EchoService.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded"  All of my nodes have .net 4 installed so I'm not quite sure what needs to be upgraded here.  Do I need to do an uninstall/reinstall of something?  What exactly needs to be installed to run these SOA samples in .net 4?

    Thanks,

    Bob

    I found the answer to this here:

    Although, in my opinion these executables should already run .net 4 by default and having to manually add a config file to make .net 4 services work is a waste of time for developers.

    Thanks for the feedback. We'll consider changing our sample based on this.

    Why would you want to change the sample?  The problem is that the HPC Server installation doesn't run .net 4 services by default and requires this config file hack to make them work.  Fix the stuff you install with HPC server, not the samples.
