Error loading project without PropertyGroup

[mhutch]

I have a project without any PropertyGroup element, which gets its TargetFramework etc via SDK imports.

The project is

<Project Sdk="Mono.UE4.Sdk" ToolsVersion="15.0">
</Project>

When I load it, I get the following error. It looks like some (but not all) code is assuming the project always has a property group.

ERROR [2018-03-27 21:24:58Z]: Error while trying to load the project /Users/mikayla/code/ProjectFae/Source/ProjectFaeMono/ProjectFaeMono.csproj

Is this the same as #4343? The exception callstack looks the same but the #4343 does not have an example project.

[mhutch]

This is #4343 🙂

[mrward]

Whoops I meant #3859 😄

[mhutch]

Ah yes, different project & project type, same bug :)
