Error in running WPF application

You may to check the following steps to catch more details on the exception : SO Question

I have encountered same issue, and I have solved this.This is caused by missing some environment dll, try to instal Visual C++ Redistributable http://www.microsoft.com/en-us/download/details.aspx?id=30679, and then run your app.

To get more info on the exception, add this method to your App.xaml.cs

public partial class App : Application {    void App_DispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e) {        Exception ex = e.Exception;        Exception ex_inner = ex.InnerException;        string msg = ex.Message + "\n\n" + ex.StackTrace + "\n\n" +            "Inner Exception:\n" + ex_inner.Message + "\n\n" + ex_inner.StackTrace;        MessageBox.Show(msg, "Application Halted!", MessageBoxButton.OK);        e.Handled = true;        Application.Current.Shutdown();    }}

And DispatcherUnhandledException="App_DispatcherUnhandledException" to your App.xaml:

<Application x:Class="MyApp.App"             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"             StartupUri="MainWindow.xaml"             DispatcherUnhandledException="App_DispatcherUnhandledException">    <Application.Resources>             </Application.Resources></Application>
