Postpone AnalyzerChanged operations when analyzer is changed on file system to prevent deadlock #11019

Our project.json should now include all Roslyn dependencies, including
reflection dependencies, so this flag shouldn't be necessary. Fixes #7907

Mark NuGet assemblies as serviceable

Add <serviceable>true</serviceable> and [assembly: AssemblyMetadata("Serviceable", "True")]

Update nuget exe

Throw BadImageFormatException decoding TypeRef with resolution scope with nil AssemblyRef

Update CoreFX to rc3-24206-00

Add support for IntPtr conversion in the call arguments optimizer.

IntPtr conversion can stay in the bound tree past lowering in a case where a COM method is invoked in an Expression Tree lambda.

Fixes: #11751

Provide a synchronous path for outlining so it won't block hte UI thread waiting for a threadpool thread.

On .NET 4.5 the implementation for NamedPipeClientStream busy waits
during the timeout period, blocking the running CPU. Fixes #10413.

fix crash due to race in build synchronization

Merging to unblock folks who are blocked on the build issue asap.

Order GlobalNamespace declarations to match Compilation.SyntaxTrees

* Tests: fix minasync Task<T> to derive from Task

* Tests: provide MinAsyncCorlibRef

This combines the async features of minasync with mincorlib to produce
a minimum unversioned corlib with async stubs.

* Compilation: use System.Object from target corlib

When creating a script compilation without an explicit return type,
System.Object was being resolved via reflection from the host.

This resulted in an implicit dependency of a script compilation on the
host corlib, even if a different corlib was specified as a reference
for the compilation (e.g. Xamarin.iOS).

Fix this by using System.Object as defined in the corlib resovled
for the compilation.

Update the branches and build badges to current targets

Suppress dynamic access to instance indexers off of types.

Provide a synchronous path for outlining so it won't block hte UI thread waiting for a threadpool thread.

Fixes some of the scenarios for https://devdiv.visualstudio.com/DefaultCollection/DevDiv/_workitems?id=204561&_a=edit.

Disallow invocation of extension methods off of types as query operators.

stabilization is now for Visual Studio 2015 Update 3, master is
targeting Visual Studio "15".

Harden active statement mapping

Fixes some of the scenarios for https://devdiv.visualstudio.com/DefaultCollection/DevDiv/_workitems?id=204561&_a=edit.

Updates CoreFX dependencies to rc3-24126-00

Add ChecksumAlgorithm to csc/vbc build task

Fixes #10451
