推荐答案
试试这个
作为By Ahmed Omer，将框架设置为4.0，而不是客户端版本。
也，设置你的平台到64位或32位，不是任何。
Try this
as By Ahmed Omer , set framework to 4.0 , not the client version.
also , set your platform to either 64 bit or 32 bit ,Not any.
转到项目的属性，
选择目标框架为.Net framework 4
和平台目标为x86或x64不使用任何。
go to the properties of your project,
choose Target framework as .Net framework 4
and Platform Target as x86 or x64 not use any.
您好Sagotharan Jagadeeswaran，
尝试这个
将Framework设置为4.0，而不是客户端版本。此外，将您的平台设置为X86或X64，而不是任何。
谢谢
