[Mono-ue] Anyone had any success with anything except Play In Editor?

Wed Dec 10 16:54:09 UTC 2014

The issue seems to be the runtime error "Failed to create shadow copy"
error is preventing the new editor process from loading the dlls. I
have seen this a few times, but not consistently enough to be able to
debug it. It seems to be something to do with having multiple
processes. If anyone finds any clues as to how to reproduce it
reliably that would be really helpful.

You mentioned building the "Development Client" configuration. The
configurations in the Visual Studio solution map into
configuration/target pairs when it invokes the Unreal Build tool. The
first part is the configuration, the second part if the target - and
if there is not a second part, it is implicitly the "Game" target.

e.g
"Development" -> Config=Development, Target=UE4Game
"Development Editor" -> Config=Development, Target=UE4Editor
"Development Client" -> Config=Development, Target=UE4Client
"Development Server" -> Config=Development, Target=UE4Server

These all result in different sets of binaries.

The UE4Game binaries are the ones used when you "stage" a build using
the "File->Package Project" from the Unreal Editor. This should work
as long as you have built the Game target for the configuration you
package - we have implemented support for staging the Mono runtime and
assemblies into the game package.

We haven't yet tested the UE4Client/UE4Server targets, since setting
them up is somewhat more complex.
