Error adding MergedDictionary to Application.Resources WPF

Question

I use MVVM light to create a “fast” WPF application to test some web services. I have the whole application, but I need to add the ResourceDictionary resource to the application resources. When I add the following to App.xaml:

<ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Resources/ResourceDictionary.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> 

I get an error message:

Error 4 Program '' does not contain a static “Basic” method suitable for entry point

All the help I can find in this error is related to the fact that the Build action is set to ApplicationDefinition, and this is not a problem.

Any help or guidance is appreciated.

TIA!

Answer 1

I had the same error when adding anything to resources in App.xaml while learning MVVM Light Toolkit. The problem is caused by incorrect dictionary declaration in <Application.Resources> and is not related to MVVM Light Toolkit.

The application resource dictionary should look like:

 <Application ...> <Application.Resources> <ResourceDictionary> <!-- Global ViewModelLocator --> <vm:ViewModelLocator x:Key="Locator" d:IsDataSource="True" /> <ResourceDictionary.MergedDictionaries> <!-- Global style --> <ResourceDictionary Source="Skin1.xaml" /> <ResourceDictionary Source="Skin2.xaml" /> <ResourceDictionary Source="Templates1.xaml" /> <ResourceDictionary Source="Templates2.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> 

Thus, you get a working global resource dictionary with the old Locator key in the same place and new keys from the dictionaries declared in the listed files.

The downloaded files are as follows:

 <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Style TargetType="{x:Type Button}"> <Setter Property="Height" Value="28" /> <Setter Property="Padding" Value="12,3" /> </Style> ... </ResourceDictionary>

Hmm, what error: does your program compile and run before you add the merge word section in App.xaml?

It may be worth checking the properties of your project - it looks like it can be installed in a console application, which by default has a static main method, which is the beginning of the application.

If it is not installed in the Console application - it is still worth checking for the "Launch Object" parameter - this can be set for a specific class, which can again be checked for the static main method as an entry point.

The entry point basically means the first that runs as part of the application.
