    <p>Previous versions of Autofac worked, but since they switched to making it a Portable Class Library it won't load.</p> <p>I tried applying the fix listed <a href="https://code.google.com/p/autofac/wiki/FrequentlyAskedQuestions">here</a> (KB2468871) but it told me that it was not needed.</p> <p>The error goes away when I move the Autofac.dll file into the same location as the executable. When it loads it from the external DLL it loads fine.</p> <p>Why won't it work as an embedded DLL?</p> <p>Here is the exception:</p> <pre><code> System.IO.FileNotFoundException: Could not load file or assembly 'System.Core, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes' or one of its dependencies.

    1. COLooks like your assembly resolve handler isn't being run. Can you confirm this? Also, it's so much easier to just use the designer to add the file as a resource. You can access it via a byte[] property [root namespace].Properties.Resources.SomeEmbeddedFile. Slam it in a MemoryStream and be done with it. GMRS is old school.

    2. CO@Will if the assembly resolve handler isn't being run, it wouldn't be able to load Autofac at all. Autofac is getting loaded, it's just having trying to load an old version of System.Core.It seems as though the Retargetable property of the assembly isn't working when it's loaded as an embedded resource. It does work when I copy the Autofac dll into the same folder as the exe.

    3. COOh, gotcha. Probably something to do with load contexts. They're damned hard to understand and they aren't documented well at all. Tried loading it yourself?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
