Use TPL Dataflow in. net 4.0

Today, I wrote a small program and used TPL Dataflow. As a result, I found a problem during deployment: the customer's server contains win2003 machines, and 2003 is not supported. net 4.5, but TPL Dataflow can only be in.. net 4.5 program.

I searched on the Internet and someone discussed this issue on the MSDN Forum. The conclusion is that although MS is intended to support it. net 4.0, but there is no corresponding version yet, but it is supported by the first version. net 4.0. However, the link provided on the MSDN forum has expired and is finally found on Stackoverflow.

After finding this 4.0 version, I replaced the 4.5 version library with it, and installed async target pack (now renamed Microsoft. bcl. to support the Async syntax sugar, the version 4.5 program was quickly downgraded to version 4.0, and the program was successfully released. If readers encounter the same problems as me, try this old library.
