Error 4 Failed to find type or namespace name "Aliyun" (is the using directive or assembly reference missing?)



Failed to find the type or namespace name "****" (is there a missing using directive or assembly reference?) error resolution
This error is due to a .net version issue
Due to the current project. .NET Framework is the .NET Framework 4 Client Profile, and this Client Profile is a stripped-down version of the .NET 4.0 framework, resulting in the reference library being unusable.
Right-click on the current project, select the Application tab on the left, and change the target framework to .NET Framework 4.


The above is what I found from the Internet, and finally found that I built a .net 4.0 project, and the library used by Alibaba was built with .net 4.5.

So, I changed my project to the .net 4.5 framework and finally solved it perfectly!!




Previous:QQ remote Win7/Win8/Win10 can see the desktop but cannot control the operation, and the solution cannot be solved
Next:VS2015 No Java Development Kit found
