Referencing third party DLL's from another project

[nelsonbrodyk]

Hey All,
I have two projects, A and B.

Inside Project A, I have a DataGrid class, that extends a third party libraries datagrid.

So the class looks like:

public class MyDataGrid : ThirdPartyDataGrid.


Now in project B, I reference Project A, and I try and use MyDataGrid, but get a compile time error saying:

Error 53 Unknown build error, 'Cannot resolve dependency to assembly 'Xceed.Wpf.DataGrid, Version=2.0.8127.13040, Culture=neutral, PublicKeyToken=ba83ff368b7563c6' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event.

Now if Project B references the Xceed (thirdParty) datagrid, then it works.

Is there a way that B can just reference A? I would hate to have all other projects that want to use my datagrid to have to actually have a copy and a reference to the dll!

Thanks for your time!

Right click on the reference you added(in your case, in project A for the 3party dll & in project B for the reference project A), Choose Properties & then set the
Copy Local property to True. Afterwards, whenever you build your project, VS will automatically copies the referred assemblies to the output folder.

Yes, but that still doesn't seem to solve the issue. It seems to force me to have Project B have a reference to Project A and to the third party dll. I was hoping to only need a dependency to project A.

Is it just a straight reference from A to B?

You're not using any of the following methods in your code?

Assembly.ReflectionOnlyLoadFrom(String assemblyFile)
Assembly.ReflectionOnlyLoad(byte[] rawAssembly)
Assembly.ReflectionOnlyLoad(String assemblyName)

No I'm not using any of those. My UI.exe just references another project that outputs a .dll. The .dll uses the other third party .dll, but when the .exe project wants to use my wrapped object from my .dll, it still wants the third party .dll.

Note: When I removed the code from XAML and did it in the code behind, the error message actually changed slightly. It gives me something similar to this:

Error 1 The type 'ClassLibrary.Class1' is defined in an assembly that is not referenced. You must add a reference to assembly 'ClassLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'

Sounds strange. I found a reference to the same problem in the Xceed forums, posted about a year ago. As of yet that post doesn't have an answer either, so I don't know if this is caused by the Xceed grid or another issue. Maybe someone else can shed some light on this one?
