今天下了TeeChart  安装中发现没有VS2012选项

在看了官网回答后  可以 如下解决

1.- Install last maintenance release of 28 September for VS2010.
2.- Open VS2012 and create new project .Net framework 4.5
3.- Add TeeChart.dll in the reference folder
4.- Build the project and run it.

如果将Teechart加入Toolbox 可以如下解决

1.- Create a new tab in the ToolBox named, e.g: TeeChart.
2.-Click with right button in new tab TeeChart of ToolBox and select Choose Items
3.- In tab .Net Framework components click browse button and select the TeeChart.dll of the path in you installed it, e.g: 
"C:\Program Files\Steema Software\Steema TeeChart for .NET 2012 4.1.2012.09280\net40\x86\TeeChart.dll"
4.- Click Ok.

关于TeeChart能否在.net 4.5工作  官网如下回答

You can use until we don‘t publish the TeeChart.dll for .Net Framework 4.5, the Teechart.dll for .Net Framework 4.0. The TeeChart.dll of VS2010 is compatible with VS2012 and .Net Framework 4.5 and should work without problems.
