+* Issue #1:  Users might obtain a NULL result when calling OperationContext.Current
+
+  This issue occurs when one creates an OperationContextScope and proceeds to call OperationContext.Current within the using clause.  A common pattern that is prone to this failure is the following:
+  
+  ```csharp
+  using (new OperationContextScope(OperationContext.Current))
+  {
+      OperationContext context = OperationContext.Current;  //OperationContext.Current returns null
+      // ...
+  }
+   ```
+
+  To work around this issue, one needs to change the code to something similar to the following:
+ 
+  ``` csharp
+  OperationContext ocx = OperationContext.Current;
+  using (new OperationContextScope(OperationContext.Current))
+  {
+      OperationContext.Current = new OperationContext(ocx.Channel);
+      // ...
+  }
+  ```
+  Issue #2:  Users might run into a deadlock when using Reentrant services.
+
+  This issue occurs when one creates a Reentrant service ? which restricts instances of the service to one thread of execution at a time.  Users prone to running into this problem will have the following ServiceBehaviorAttribute in their code:
+
+  ```csharp
+  [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Reentrant)]
+  ```
+  To work around this issue, users should set the ConcurrencyMode of their service to ConcurrencyMode.Single or ConcurrencyMode.Multiple, and provide the appropriate synchronization primitives to ensure a single thread can execute a single method at a time.
+
+  We have rolled out an update of System.ServiceModel.dll and we strongly encourage users to patch their existing .NET 4.6.2 framework.  The patch fixes Issue #1, disables the flow of OperationContext.Current by default, and provides an Opt-In option to enables feature.
+
+  To enable the flow of OperationContext.Current across multiple threads in async operations, use the following AppSettings key:
+  
+  ```xml
+  <appSettings>
+    <add key="Switch.System.ServiceModel.DisableOperationContextAsyncFlow" value="false"/>
+  </appSettings>
+  ```
+  Setting the value of Switch.System.ServiceModel.DisableOperationContextAsyncFlow to true will disable the flow of the ExecutionContext in OperationContext.Current and will effectively revert the behavior to pre-4.6.2, which is the default behavior after this patch.  Setting the value to false will enable the feature and should not be used in Reentrant services. [253477] [Added: May 2017]

+* On a machine with many processors, there might a desire to have some processes use only some processes with Server GC. For example if you have a 40-proc machine, you might want to have process 0 use only 10 procs and process 1 use only 6. So process 0 gets 10 GC heaps/threads and process 1 gets 6. Below is an example of using these Server GC configs:
+
+    ```xml
+    <configuration>
+    <runtime>
+        <gcServer enabled="true"/>
+        <GCHeapCount enabled="6"/>
+        <GCNoAffinitize enabled="true"/>
+        <GCHeapAffinitizeMask enabled="144"/>
+    </runtime>
+    </configuration>
+    ```
+
+   `<GCNoAffinitize enabled="true"/>` specifies to not affinitize the Server GC threads with CPUs.
+    `<GCHeapCount enabled="6"/>` 6 specifies you want 6 heaps. The actual # of heaps is the min of what you specify and what your proces is allowed to use.
+    `<GCHeapAffinitizeMask enabled="144"/>` the # is in decimal so this is 0x90, meaning you want to use those 2 bits as your process mask. The actual # of heaps is the min of what you specify, what your proces is allowed to use and the # of set bits in this mask you specify. [274126] [Added: May 2017]

+* Applications that frequently queue bursts of work items to the .NET ThreadPool, with idle or light activity between bursts, may be shown using PerfView to spend a significant amount of CPU time in clr!ThreadpoolMgr::UnfairSemaphore::Wait in a spin-wait. A new configuration variable is exposed to configure the spinning limit. The environment variable COMPlus_ThreadPool_UnfairSemaphoreSpinLimit may be set to a lower value (default is 0x32) to reduce the amount of spinning done, or zero (0) to disable spinning, before launching the application. Note that changes to this configuration variable may negatively affect the performance of applications, and such changes are not supported. [381905] [Added: May 2017]
