+# Apache Thrift netstd
+
+Thrift client library for Microsoft .NET Standard 
+
+# Build the library
+
+## How to build on Windows
+- Get Thrift IDL compiler executable, add to some folder and add path to this folder into PATH variable
+- Open the Thrift.sln project with Visual Studio and build.
+or 
+- Build with scripts
+
+## How to build on Unix/Linux
+- Ensure you have .NET SDK >= 2.0 installed, or use the [Ubuntu docker image](../../build/docker/README.md)
+- Follow common automake build practice: `./ bootstrap && ./ configure && make`
+
+## Known issues
+- In trace logging mode you can see some not important internal exceptions
+
+# Migration to netstd
+
+## ... from netcore
+
+If you are migrating your code from netcore library, you will have to:
+
+- Switch to `thrift -gen netstd`
+- the following compiler flags are no longer needed or supported: `hashcode` is now standard, while `nullable` is no longer supported.
+- the `Thrift.Transport` and `Thrift.Protocol` namespaces now use the singular form
+- add `using Thrift.Processor;` in the server code where appropriate
+- rename all `T*ClientTransport` to `T*Transport` 
+- rename all `TBaseServer` occurrences in your code to `TServer`
+- the `SingletonTProcessorFactory` is now called `TSingletonProcessorFactory`
+- and the `AsyncBaseServer` is now the `TSimpleAsyncServer`
+
+You may wonder why we changed so many names. The naming scheme has been revised for two reasons: First, we want to get back the established, well-known naming consistency across the Thrift libraries which the netcore library did not fully respect. Second, by achieving that first objective, we get the additional benefit of making migration at least a bit easier for C# projects.
+
+## ... from csharp
+
+Because of the different environment requirements, migration from C# takes slightly more efforts. While the code changes related to Thrift itself are moderate, you may need to upgrade certain dependencies, components or even modules to more recent versions. 
+
+1. Client and server applications must use at least framework 4.6.1, any version below will not work. 
+1. Switch to `thrift -gen netstd`. The following compiler flags are no longer needed or supported: `hashcode` and `async` are now standard, while `nullable` is no longer supported.
+1. [Familiarize yourself with the `async/await` model](https://msdn.microsoft.com/en-us/magazine/jj991977.aspx), if you have not already done so. As netstd does not support `ISync` anymore, async is mandatory. The synchronous model is simply no longer available (that's also the reason why we don't need the `async` flag anymore). 
+1. Consider proper use of `cancellationToken` parameters. They are optional but may be quite helpful.
+1. As you probably already guessed, there are a few names that have been changed:
+- add `using Thrift.Processor;` in the server code where appropriate
+- the `TServerSocket` is now called `TServerSocketTransport`
+- change `IProtocolFactory` into `ITProtocolFactory`
+- if you are looking for `TSimpleServer`, try `TSimpleAsyncServer` instead
+- similarly, the `TThreadPoolServer` is now a `TThreadPoolAsyncServer` 
+- the server's `Serve()` method does now `ServeAsync()`
+- In case you are using Thrift server event handlers: the `SetEventHandler` method now starts with an uppercase letter
+- and you will also have to revise the method names of all `TServerEventHandler` descendants you have in your code

+/** 
+ * 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.

+    * TMultiplexedProtocol is a protocol-independent concrete decorator that allows a Thrift

+    * to the function name during function calls.
+    *
+    * NOTE: THIS IS NOT TO BE USED BY SERVERS.
+    * On the server, use TMultiplexedProcessor to handle requests from a multiplexing client.
+    *
+    * This example uses a single socket transport to invoke two services:
+    *
+    *     TSocketTransport transport = new TSocketTransport("localhost", 9090);
+    *     transport.open();

+# Building of samples for different platforms 
+
+# Reused components 
+- NET Core Standard 2.0
+- NET Core App 2.0
+
+# How to build
+- Download and install the latest .NET Core SDK for your platform https://www.microsoft.com/net/core#windowsvs2015 (archive for SDK 1.0.0-preview2-003121 located by: https://github.com/dotnet/core/blob/master/release-notes/download-archive.md)
+- Ensure that you have thrift.exe which supports netstd lib and it added to PATH 
+- Go to current folder 
+- Run **build.sh** or **build.cmd** from the root of cloned repository
+- Check tests in **src/Tests** folder
+- Continue with /tutorials/netstd 
+
+# How to run 
+
+Notes: dotnet run supports passing arguments to app after -- symbols (https://docs.microsoft.com/en-us/dotnet/articles/core/tools/dotnet-run) - example: **dotnet run -- -h** will show help for app
+
+- build 
+- go to folder (Client/Server) 
+- run with specifying of correct parameters **dotnet run -tr:tcp -pr:multiplexed**, **dotnet run -help** (later, after migration to csproj and latest SDK will be possibility to use more usable form **dotnet run -- arguments**)
+
+#Notes
+- Possible adding additional platforms after stabilization of .NET Core (runtimes, platforms (Red Hat Linux, OpenSuse, etc.) 
+
+#Known issues
+- In trace logging mode you can see some not important internal exceptions
+
+# Running of samples 
+Please install Thrift C# .NET Core library or copy sources and build them to correcly build and run samples 
+
+# NetCore Server
+
+Usage: 
+
+    Server.exe -h
+        will diplay help information 
+
+    Server.exe -tr:<transport> -pr:<protocol> 
+        will run server with specified arguments (tcp transport and binary protocol by default)
+
+Options:
+
+    -tr (transport): 
+        tcp - (default) tcp transport will be used (host - ""localhost"", port - 9090)
+        tcpbuffered - tcp buffered transport will be used (host - ""localhost"", port - 9090)
+        namedpipe - namedpipe transport will be used (pipe address - "".test"")
+        http - http transport will be used (http address - ""localhost:9090"")
+        tcptls - tcp transport with tls will be used (host - ""localhost"", port - 9090)
+        framed - tcp framed transport will be used (host - ""localhost"", port - 9090)
+
+    -pr (protocol): 
+        binary - (default) binary protocol will be used
+        compact - compact protocol will be used
+        json - json protocol will be used
+		
+Sample:
+
+    Server.exe -tr:tcp
+
+**Remarks**:
+
+    For TcpTls mode certificate's file ThriftTest.pfx should be in directory with binaries in case of command line usage (or at project level in case of debugging from IDE).

+# 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 netstd 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
