"The invocation of the constructor on type 'TestWPF.MainWindow' that matches the specified binding constraints threw an exception."- how to fix this?

Question

I'm working with WPF. When I'm trying to declare SQLiteConnection in the code, the problem arises-

The invocation of the constructor on type 'TestWPF.MainWindow' that matches the specified binding constraints threw an exception.  InnerException: Make sure that the file is a valid .NET Framework assembly. 

can anyone tell me, how to fix it?

Answer 1

If you click on View Detail... from the exception window you can look at the InnerException. Expand that node and you will see exactly what went wrong.
