Today in this article, we will cover below aspects,

  • Issue Description
  • Resolution

Issue Description

WPF application runtime gives below error,

System.Windows.Markup.XamlParseException
Message=’No matching constructor found on type MissingMethodException: No default constructor found for type ‘WPFDesktopApp.EmployeeWindow’. You can use the Arguments or FactoryMethod directives to construct this type.

XamlParseException No matching constructor found on type

Resolution

This issue is more visible when you try to provide a custom instance of the Window object.

For Example, The issue is common when the target Window is being instantiated with parameterized constructor etc. 

 public partial class EmployeeWindow : Window
    {

        private readonly IEmployeeViewModel _businessObject;
        public EmployeeWindow(IEmployeeViewModel business)
        {
            InitializeComponent();
            _businessObject = business;

        }
...

   }

In such cases, please remove default StartupUri property being set in the App.xaml file.

No matching constructor found on type

The issue resolves once the above line is removed.

I have written a WPF application, on my compuyter it is running ok.
Now I am trying to deploy wpf application on W7 computer. And getting following exception:

Юрий, добрый день!

Ошибка XAML больше не показывается, приложение SampleConnection запустилось.
И выдало новую ошибку

  • Question

  • I can run my WPF application.exe file locally fine, however if I copy the executable to another machine I get a Windows report error dialog. The only useful error info I see is:

    system.windows.markup.xamlparse

    I am including the referenced dlls. Is there anything else that could cause this?

Answers

  • It is more then likely a problem with your xaml that is only discovered at runtime.  For example if you you reference a static resource that doesn’t exist, you will get the exception you mentioned.  Here would be an example of offending code, because
    MissStyle does not exist.

    <TextBlock Style=»{StaticResource MissingStyle}»/>

    To find out what the exact problem is  you may have to set up the IDE to break on WPF exceptions:
    –Open the «Exceptions» window (Debug/Exceptions) in Visual Studio.
    –Click “Add»
    — Set Type to “Common Language Runtime Exceptions”
    — Set Name to “System.Windows.Markup.XamlParseException”
    — Hit “OK”
    — Check the box to “Break on Thrown”

    Run the app again and it should break on the line that has the issue.

There is an exception which many people hit when first creating dependency properties.

System.Windows.Markup.XamlParseException: The invocation of the constructor on type ‘[type name here]’ that matches the specified binding constraints threw an exception.

Don’t worry – it’s very easy to fix and also very commonly made.

You first dependency property may look something like this, especially if you use the code snippet “propdp“.

        public long MyProperty
        {
            get { return (long)GetValue(MyPropertyProperty); }
            set { SetValue(MyPropertyProperty, value); }
        }

        public static readonly DependencyProperty MyPropertyProperty =
            DependencyProperty.Register(
                "MyProperty",
                typeof(long),
                typeof(MyClass),
                new PropertyMetadata(0));

If you created your code using the code snippet it will compile just fine and the world will be a happy place. The problem lies in the constructor of the PropertyMetadata on line 12 above where you set the default value for the property.

The definition of the constructor is:

public PropertyMetadata(object defaultValue);

The type of the parameter ‘defaultValue‘ is ‘object‘, this means that your default value will be boxed as an object type.

The error comes when the default value is needed and is unboxed. If you didn’t carefully force the type of the value going in then the most sensible type will be chosen by the compiler, which may differ from the type you specified on line 10, i.e. the underlying type you wish to use for your dependency property.

Using the above as an example, the default value is set to ‘0‘ – the compiler will interpret ‘0‘ to be an Int32 and then the constructor will store that Int32 typed value as the default value in the defaultValue object.

When you come to need the default value the code that is executed behind the scenes will attempt to turn your default value back to the type specified for your dependency property, i.e.

long value = (long)defaultValue;

Much to many people’s surprise, this is not possible and will throw the exception above. Why? Well, you need to unbox back to the underlying type before you cast it to another type.

Take the following code, which you can paste into a console project to check out:

var myInt = 0;
Console.WriteLine(myInt.GetType().Name); // produces Int32

object myObj = myInt;
Console.WriteLine(myObj.GetType().Name); // produces Int32 - the underlying type

// no problem
long myLong1 = (long)myInt;

// no problem - unboxing to int and then casting to long
long myLong2 = (long)(int)myObj;

// exception - can't unbox to a different type
long myLong3 = (long)myObj;

Note that on line 1 I declared the variable using var instead of int, however we can still see that the compiler has decided that Int32 is the best way to go with this value.

So, back to the exception, and how to correct it. Simple really, make sure that the compiler is aware of the type of value that you are passing in and make sure that it matches the type you are declaring for your dependency property.

In the example above we only need to replace line 12 with the following using an explicit cast.

                new PropertyMetadata((long)0));

Alternatively we could have used a type suffixes as a shortcut.

 new PropertyMetadata(0l));

Other type suffices are:
u – uint
l – long
ul – ulong
f – float
d – double
m – decimal

If you are interested in a more depth article on boxing and unboxing and casting in general, see Eric Lippert’s excellent blog post.
