I wish I knew what I did to cause this, but I cannot use the
Visual Studio
2008 Designer at all with with MVVMLight templates. I receive a "Could not create an instance of type 'ViewModelLocator'. in any of my xaml pages. The application builds and runs fine but only the designer is broken. In the App.xaml is
<Application x:Class="ExcelReportGenerator.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:vm="clr-namespace:ExcelReportGenerator.ViewModel"
xmlns:res="clr-namespace:ExcelReportGenerator.Resources"
Startup="Application_Startup"
mc:Ignorable="d">
<Application.Resources>
<!--Global View Model Locator-->
<vm:ViewModelLocator x:Key="Locator"
d:IsDataSource="True" />
</Application.Resources>
I even receive the error when I create a brand new MVVMLight application. The interesting thing is if I use an express version of VS2010 I can view, edit and work in designer just fine. As much as I would love to go to VS2010, I can't right now convince IT to make that move.
