Investigate whether we need to do anything special for `dotnet publish` to work

[alexrp]

It seems to be fine:

$ dotnet publish
Microsoft (R) Build Engine version 17.0.0-preview-21302-02+018bed83d for .NET
Copyright (C) Microsoft Corporation. All rights reserved.

  Determining projects to restore...
  All projects are up-to-date for restore.
  You are using a preview version of .NET. See: https://aka.ms/dotnet-core-preview
  clib -> C:\Users\alex\source\repos\zig-msbuild-sdk\src\samples\clib\bin\Debug\win-x64\clib.dll
  clib -> C:\Users\alex\source\repos\zig-msbuild-sdk\src\samples\clib\bin\Debug\win-x64\publish\

~/source/repos/zig-msbuild-sdk/src/samples/clib  master
$ ls bin/Debug/win-x64/publish/
clib.dll  clib.pdb

But there may be edge cases we aren't covering.

This might tie into:

• Project and package reference support #8

Closing; see:

• dotnet build followed by dotnet publish --no-build does not work #34
