C# 设计器无法在visual studio中加载，常规参数[0]违反了类型参数的约束'；T'；

我有一个GUI，其中包含几个infragistics元素，当我加载它们时，会出现错误

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VisualStudio中

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.

没有其他设计师在展示任何有意义的东西，他们要么抛出上述错误之一，要么向我展示一个小的空白设计师屏幕

我已经尝试过删除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，我发现可能是关于冲突的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Infrastic版本，而只有一个s文件，这表明它已经严重过时

我已经尝试删除bin和obj文件夹。
