启动时加载主窗口XamlParseException的异常

Question

getting and Exception thrown: 'System.Windows.Markup.XamlParseException' in PresentationFramework.dll additional information 'The invocation of the constructor on type 'Wpf.Controller' that matches the specified binding constraints threw an exception.'

Where Wpf.Controller is just a controller class.... so, I've re-targeted a WPF app as a dll, and have some environmental WPF applications using that XAML dll as the core UI. (minor changes to wpf.exe to help deployment).

This error isn't happening will all the wpf.exe projects... (3 of the 5 are running without issue - the code is the same, outside some app.config and properties which have deployment differences.

Answer 1

When I re-targeted the WPF.exe to a wpf.dll, I didn't change it's name, so the wpf.dll and wpf.exe project clashed. Once I renamed the dll to something else, it all worked. Error made sense, but a gotcha.
