We need to write transitive reference assemblies to the deps.json file.

[moh-hassan]

I have a solution in vs2017.3 RTM with two projects ConsoleAppCore2 and NetStand2Lib.
.Netcore2 console application ('ConsoleAppCore2') reference NetStand2Lib project (NetStand2Lib)

The NetStand2Lib project reference mylib.dll which is .Net Framework 45 (net45).
The compilation is successful and mylib.dll is copied to the bin folder.
When I try to run the application, I get run-time exception error:

System.IO.FileNotFoundException occurred
HResult=0x80070002
Message=Could not load file or assembly 'mylib, Version=10.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'. The system cannot find the file specified.

I inspected the generated dependency of ConsoleAppCore2.deps.json file and find **no entry for dependency at all ** to mylib.dll, below is part of deps.json :

		  {
		  "runtimeTarget": {
			"name": ".NETCoreApp,Version=v2.0",
			"signature": "78d5ac0bccb1c0063faa39eccad7f2c5c81c635a"
		  },
		  "compilationOptions": {},
		  "targets": {
			".NETCoreApp,Version=v2.0": {
			  "ConsoleAppCore2/1.0.0": {
				"dependencies": {
				  "NetStand2Lib": "1.0.0"
				},
				"runtime": {
				  "ConsoleAppCore2.dll": {}
				}
			  },
                               ..........

My workaround solution:
I explicitly added mylib.dll as a reference in ConsoleAppCore2 project. , I find an entry in the file ConsoleAppCore2.deps.json to mylib.dll and it's working fine.

i reached these issues #5954 , #120, but they can't help.

What i missed to avoid my workaround solution and avoid the reference twice to mylib.dll
Or is this a waiting support feature?

Should be fixed with #2090
