* Workaround problems when opening solution files in Visual Studio (#4569)
Changes:
* Condense Routing.sln into HttpAbstractions.sln
* Workaround NU1105 by adding all ProjectReferences to the .sln
* Workaround exceptions in the ReferencesHostBridge by moving Reference items to a temporary item group
* Add a 'startvs.cmd' script for launching VS with the right env variables
* Remove RangeHelper test project
* Move RangeHelper tests into StaticFiles.Tests and add target for NPM restore
* Convert Session to use Reference and move to Middleware folder (#4576)
* Add RoutingSample.Web to HttpAbstractions.sln
Changes:
* Stop producing Microsoft.AspNetCore.Routing.DecisionTree.Sources. I could not find any usages outside of the Microsoft.AspNetCore.Routing assembly, so I've moved this to be a subfolder of code in the Microsoft.AspNetCore.Routing project.
* Stop building src/Routing as a submodule. Use ProjectReference instead
* Move projects from src/Routing into src/Http/Routing/ and src/Http/Routing.Abstractions/
* Update package baselines and dependencies to support building routing projects and samples
* corefx to preview.18571.3
* core-setup to 3.0.0-preview-27122-01
* buildtools to 3.0.0-build-20181120.4
* extensions to 3.0.0-preview.18572.1
* efcore to 3.0.0-preview.18572.1
Fix#4172 - remove signcheck exclusion for core-setup files
This changes the way Microsoft.AspNetCore.App works to follow patterns set by Microsoft.NETCore.App. Instead of being a metapackage with dozens of dependencies, this package has no dependencies. It uses RID-splitting to deliver standalone assets for self-contained deployments.
Changes:
* Implements RID-split packages for Microsoft.AspNetCore.App.
* Update shared fx deps.json generation to only include entries for the RID-specific metapackages
* Include platform-specific packages in publish output
* Remove all nuspec dependencies of Microsoft.AspNetCore.App and collect all references into the package.
* Replace the aspnet/JsonPatch git submodule and merge the master branch of its source to this repo
* Likewise for aspnet/DotNetTools
* And aspnet/HtmlAbstractions
* merge latest infrastructure changes from the release/2.2 branch
