Unity part of the Build FAILED. error C2259

[lingfei1998]

when running the 'build.cmd' in Unity folder it fails

I find a previous question exactly like mine

• Unity part of the Build FAILED. error C2259 #1964

here is the error message

“C:\Users\ling\source\repos\AirSim\Unity\AirLibWrapper\AirsimWrapper.sln”(Clean;Build 目标) (1) ->

ibWrapper\AirsimWrapper\AirsimWrapper.vcxproj]

Looks the same as the 1964 question

I made sure I downloaded the latest version，but I do not know how to solve it

Hi,
Please try out the fixes done in #2514, I have tested it on Linux only, would be great to know whether it works on Windows or not

yes, it works on Windows now. Thank you.
