I notice in the Harness project there is some design time support using the ViewModelLocator and DesignTimeResourceMgtUnitOfWorkManager.

I am trying to get this going, for example on the StaffingResourceSummaryView. However, when I switch over to design view, it throws an error:

You must first set a valid CompositionProvider by using Composition.SetProvider.

I like the idea of Design time support as when I am tweaking out a GUI, getting a visual is the only way to go.

Is this happening in TempHire or your own solution? If it's in TempHire, can you do me a favor and open a bug on github?

Greg,
I wanted to set some expectations before I fix this bug. Currently, DevForce doesn't fully support design time data. In particular you can't use code-first at design time. There are security constraints at design time that cause DF to fail when trying to load the metadata. You can suggest a feature on our new User Voice site for DevForce if full design time data support is important to you. I can fix the current bug in Cocktail, but that only gets you so far.

Hi Marcel,

Don't worry about this. I have been able to get what I want by using:

d:DataContext="{d:DesignInstance Type=designTime:DesignTimeViewModel, IsDesignTimeCreatable=True}"

All I do is create a DesignTimeViewModel with one property of an Entity. I just hand code a bit of data into the entity and it all shows up in the designer just fine.

So that's really all I need to lay out a view.

Greg
