我有一个包含几个infragistics元素的GUI，当我加载它们时会给我错误
GenericArguments[0], 'Infragistics.Win.UltraWinTabControl.UltraTab', on 'Infragistics.Win.Design.SubObjectCodeDomSerializer`1[T]' violates the constraint of type parameter 'T'.
使用堆栈跟踪：
at System.RuntimeTypeHandle.Instantiate(RuntimeTypeHandle handle, IntPtr* pInst, Int32 numGenericArgs, ObjectHandleOnStack type)
at System.RuntimeTypeHandle.Instantiate(Type[] inst)
at System.RuntimeType.MakeGenericType(Type[]
这是在视觉工作室。
加载设计器时同一项目中的其他错误包括：
Object reference not set to an instance of an object.

没有其他设计师表现出任何明智的事情，他们要么抛出上述错误之一，要么向我展示小空设计师的画面。
我已经尝试删除bin / obj并构建一个干净的版本但是没有，在互联网上的其他地方我发现可能是冲突的infragistis版本可能是问题的一部分。但是这建议在程序集中卸载它们，但是这似乎假设程序集中有多个infragistic版本，而那里只有一个单个文件，这表明它已经过时了。
