Error opening existing project RRS feed

  • Question

  • I've been using the same Visual Studios project for months and suddenly I'm getting the following error when I try to open it:

    "The number of generic arguments provided doesn't equal the arity of the generic type definition.  Parameter name: instantiation"

  • Hi Dana Knight,

    Thank you for posting in MSDN forum.

    The error message seems to be a compiler error, and this forum is discuss Visual Studio WPF/SL Designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System, and Visual Studio Editor.

    To redirect you to the correct forum, could you please tell us your project type, the language in your code, C#, vb or others?

    Besides, would you mind show us your code that related to this error?

    Best Regards,

    Jiayi Li
