Howdy,

Have downloaded Godot 3 today, very keen to have a look and see what Godot is all about. Am having a lot of trouble getting started however...

My system has recently been completely reformatted so I'm starting 100% fresh, no dev tools or build tools or anything. Previously was setup to build for/with Unreal Engine and Unity 3D, but having done little-to-no gamedev in the last 12 months I'm very keen to keep the install footprint as small as possible.

Through the course of trying to get going the primary things I've downloaded and installed are:

• Godot 3.0.1 with Mono support
• Mono 5.4.1.7 & Mono 5.4.0.201
• VS Code
• VS Build Tools
• MS .NET Framework 4.5.2 Dev Pack

Have tried a couple other versions of MS .NET Framework, and Mono.

Running Windows 10 (with Fall Creators Update).

A snippet of startup log when running Godot with -v:

Mono: Initializing module...
Mono: Logfile is C:\Users\Dan\AppData\Roaming/Godot/mono/mono_logs/1520059173.txt
Mono: Runtime initialized
Mono: Loading assembly mscorlib...
Mono: Assembly mscorlib loaded from path: C:\Program Files\Mono\lib\/mono/4.5/mscorlib.dll

Mono: Loading scripts domain...
Mono: Debugger wait timeout
Mono: Loading assembly GodotSharp...
Mono: Failed to load Core API assembly
Mono: INITIALIZED

This line is of particular interest:

Mono: Failed to load Core API assembly

There is a build error in the Output view, but the message is far too long to view in both the list of errors and the tooltip that appears when hovering the message so can't be sure of what it says. Doesn't seem to be a way to copy that message out, nor does it appear in the Godot log in the console.

When opening the generated project in VS Code there is an OmniSharp.MSBuild.ProjectLoad error, which includes the text The reference assemblies for framework ".NETFramework,Version=v4.5" were not found.

Have tried a number of solutions when Googling for that last error, but have had no success. Needless to say, my goal of having a minimal install footprint is slipping while I install all these packages to try and solve the problem...

Has anyone had this problem and found a solution to it? Either my Google-fu is weak or it's not a common issue.
