    <p>I ran into an issue today that is making me pull my hair out. </p> <p>I've created a WCF service which is fairly simple as it only exposes two operations and no data contracts. This WCF service sits on top of a business logic layer. Inside this business logic layer is a dll which exposes some contracts (just plain interfaces). </p> <p>I've also created two test clients for the service. One is a console client and the other is a MVC4 application. Both reference the same endpoints and they both reference, through a project reference, the contract dll.</p> <p>Now, all is fine until I change the contract by adding or removing a method, or even changing the signature of an existing method. At that point my MVC4 app blows and throws all over the place. Keep in mind that I'm not changing the WCF contract, just some internal contracts.</p> <p>The reason is that inside of the business logic layer I am initializing my AutoMapper profiles via a static constructor. Inside this static constructor I basically get all the assemblies of the current domain and iterate through them looking for objects that implement IProfile. It's when I start trying to get types out of one of the dlls that reference the contracts dll that I get a fatal exception: System.TypeLoadException.</p> <p>Now, the console client behaves just fine. Again, referencing the same dll's through a project reference. I can change that contracts dll all day long and it's just happy as a lark, but MVC4 blows chunks. If I go back and make the interface exactly like it was before MVC4 is happy.</p> <p>I noticed that the path to the assembly that was failing to load is in the Temporary ASP.Net files location. I blasted that entire directory and still no luck.</p> <p>I can supply code, but it might be better if I gave you a dependency graph. There's already about 5k lines of code in the BLL.</p> <p>Thanks in advance.</p>

    1. COAre you updating service reference after making changes to WCF? You have such option when right-clicking on service reference in your MVC project

    2. COI'm not changing the WCF contract, just some internal shared contracts. So a shared dll between both the WCF and the MVC app is changing. I didn't think I needed to update the service reference for a shared dll, but I'll give it a shot. Thanks!

    3. COI'm suspicious about "one of the dlls that reference the contracts dll". Are you certain that dll is being rebuilt after you change the contracts dll? I've had cases where a project was accidentally using an assembly reference rather than a project reference, causing problems like those you describe. Have you decompiled the assembly which triggers the problem to double check that it's up-to-date?

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.
