Why Can't My ObjectContext Load Metadata? (MetadataException: Unable to Load Specified Metadata Resource)

Debugging the "MetadataException: Unable to Load Specified Metadata Resource" Error

This error, encountered when creating an ObjectContext, usually stems from several potential issues:

1. Incorrect MetadataArtifactProcessing Setting

Double-check your model's MetadataArtifactProcessing property. If it's set to "Copy to Output Directory," the EDMX won't be embedded in your assembly, leading to runtime errors.

2. Connection String Validation

Even if your connection string looks right, ensure it hasn't been affected by recent changes, especially those altering assembly names. Carefully review and update it as needed.

3. EDMX Embedding Issues

If you use a post-build task to embed the EDMX, verify its proper functionality. External factors could have disrupted this process. Investigate the task and its dependencies for clues.

Without more context, pinpointing the precise cause is impossible. However, these points offer a solid starting place for your troubleshooting efforts.
