Running k web from mapped network drive causes unhandled exception (klr.exe has stopped working)

[clintkolodziej]

When running the 'k web' command from one of the samples (HelloWeb, HelloMvc) from a mapped network drive (w:) I get the following unhandled exception. Probably not a bad idea to just output an error message, or a security confirmation message asking the user if it is safe to run, rather than crashing out the klr.exe.

Output from the command:

W:\repositories\Home\samples\HelloMvc>k web

Out of interest, can you run it when using -svrc50?

[clintkolodziej]

Works fine with -svrc50, fails with -svr50:

Is there a workaround for this?
