Hi,
How does one use, 
IdeaBlade.EntityModel.EntityMetadataStore.Instance.LoadMetadataFromEmbeddedResources(assembly);

Any possiblity of doing this sort of thing, if probing is not possible?
IdeaBlade.EntityModel.EntityMetadataStore.Instance.LoadMetadataFromAnyModelAssembly(assembly);
thanks
John

Why do you want to call this directly?
 
It's actually something used internally by DevForce when looking for and initializing Code First models.  The method will search for any *.ibmmx files embedded in the given assembly and merge the contained metadata into the EntityMetadataStore.  This all happens automatically, or is supposed to, whenever a new entity type is seen in a query or save list.  The assembly normally passed into the method is one holding entity declarations, so should already be probed.
 
If you're seeing a problem with your Code First entities, please let us know the details of the problem.

Hi,
Thanks for response. Idle interest really! I noticed it and was wondering why there wasn't a family of such methods!

I was trying to get the metadata from within a T4 template, but the metadata store instance was returning nothing.
var et =  IdeaBlade.EntityModel.EntityMetadataStore.Instance.GetEntityTypes();
I suppose the MEF probing couldn't operate correctly.

Since then I've moved over to a PreProcessed T4 template and it's working fine.

thanks
John

That's great that you found an answer to your issue with the preprocessed templates.
 
Regarding MEF probing - at design/build time the only way to have MEF probe an assembly is to add it to the IdeaBladeConfig ProbeAssemblyNames collection, since the normal MEF probing is turned off.
