Ah the good old error You most likely seen it looking something like this The type 'Prometer.Objects.AnalysisEngineData' is ambiguous: it could come from assembly 'C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\aa63ddac\c47315b5\App_Code.8t9ff09n.DLL' or from assembly 'C:\Projects\Webbprojects\Prometer\bin\Prometer.DLL'. Please specify the assembly explicitly in the type name.

In short

Now there are quite a few tricks out there that suggest how to solve this. None of them shows to be correct unless you are really lucky. In general this error depend on a structural error in your Visual Studio project. That means this can be solved by either moving the file or by changing the "Build Action" from Compile to Content.

In reasonable depth

This occur when an aspx page tries to reach a class (like an objectdatasource) and tries to (or actually do) compile the class. But since it's already compiled everything will fail. Now in the case shown above I had put my class libraries in the App_Code directory and set the "Build Action" to "Compile" on each library. This solution works but will fail if an aspx-page tries to reach a library since it will build it's own version of the library (stupid). Now I can solve this by leaving my files in the App_Code folder just setting the "Build Action" to "Content" instead. But other things might fail doing that. The best option is to move the class libraries to a separate directory, in example "/Classes". If so done remember to set the "Build Action" to "Compile".

If in App_Code

If in /Classes

So that should be it, please not that there are no work around for this. The structure has to be correct otherwise it simply wont work. Good luck!
