+# SYNOPSIS
+#
+#   AX_PROG_DOTNETCORE_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE])
+#
+# DESCRIPTION
+#
+#   Makes sure that .NET Core supports the version indicated. If true the
+#   shell commands in ACTION-IF-TRUE are executed. If not the shell commands
+#   in ACTION-IF-FALSE are run. The $dotnetcore_version variable will be
+#   filled with the detected version.
+#
+#   This macro uses the $DOTNETCORE variable to perform the check. If
+#   $DOTNETCORE is not set prior to calling this macro, the macro will fail.
+#
+#   Example:
+#
+#     AC_PATH_PROG([DOTNETCORE],[dotnet])
+#     AC_PROG_DOTNETCORE_VERSION([1.0.2],[ ... ],[ ... ])
+#
+#   Searches for .NET Core, then checks if at least version 1.0.2 is
+#   present.

+ * The ConsistencyLevel is an enum that controls both read and write
+ * behavior based on the ReplicationFactor of the keyspace.  The
+ * different consistency levels have different meanings, depending on
+ * if you're doing a write or read operation. 
+ *
+ * If W + R > ReplicationFactor, where W is the number of nodes to
+ * block for on write, and R the number to block for on reads, you
+ * will have strongly consistent behavior; that is, readers will
+ * always see the most recent write. Of these, the most interesting is
+ * to do QUORUM reads and writes, which gives you consistency while
+ * still allowing availability in the face of node failures up to half
+ * of <ReplicationFactor>. Of course if latency is more important than
+ * consistency then you can use lower values for either or both.
+ * 
+ * Some ConsistencyLevels (ONE, TWO, THREE) refer to a specific number
+ * of replicas rather than a logical concept that adjusts
+ * automatically with the replication factor.  Of these, only ONE is
+ * commonly used; TWO and (even more rarely) THREE are only useful
+ * when you care more about guaranteeing a certain level of
+ * durability, than consistency.
+ * 
+ * Write consistency levels make the following guarantees before reporting success to the client:
+ *   ANY          Ensure that the write has been written once somewhere, including possibly being hinted in a non-target node.
+ *   ONE          Ensure that the write has been written to at least 1 node's commit log and memory table
+ *   TWO          Ensure that the write has been written to at least 2 node's commit log and memory table
+ *   THREE        Ensure that the write has been written to at least 3 node's commit log and memory table
+ *   QUORUM       Ensure that the write has been written to <ReplicationFactor> / 2 + 1 nodes
+ *   LOCAL_QUORUM Ensure that the write has been written to <ReplicationFactor> / 2 + 1 nodes, within the local datacenter (requires NetworkTopologyStrategy)
+ *   EACH_QUORUM  Ensure that the write has been written to <ReplicationFactor> / 2 + 1 nodes in each datacenter (requires NetworkTopologyStrategy)
+ *   ALL          Ensure that the write is written to <code>&lt;ReplicationFactor&gt;</code> nodes before responding to the client.
+ * 
+ * Read consistency levels make the following guarantees before returning successful results to the client:
+ *   ANY          Not supported. You probably want ONE instead.
+ *   ONE          Returns the record obtained from a single replica.
+ *   TWO          Returns the record with the most recent timestamp once two replicas have replied.
+ *   THREE        Returns the record with the most recent timestamp once three replicas have replied.
+ *   QUORUM       Returns the record with the most recent timestamp once a majority of replicas have replied.
+ *   LOCAL_QUORUM Returns the record with the most recent timestamp once a majority of replicas within the local datacenter have replied.
+ *   EACH_QUORUM  Returns the record with the most recent timestamp once a majority of replicas within each datacenter have replied.
+ *   ALL          Returns the record with the most recent timestamp once all replicas have replied (implies no replica may be down)..

+# How to test communication between NetCore and Python
+
+* Generate code with the latest **thrift.exe** util
+* Ensure that **thrift.exe** util generated folder **gen-py** with generated code for Python
+* Create **client.py** and **server.py** from the code examples below and save them to the folder with previosly generated folder **gen-py**
+* Run netcore samples (client and server) and python samples (client and server)
+
+Remarks:
+
+Samples of client and server code below use correct methods (operations) 
+and fields (properties) according to generated contracts from *.thrift files
+
+At Windows 10 add record **127.0.0.1 testserver** to **C:\Windows\System32\drivers\etc\hosts** file
+for correct work of python server
