Using different DLL's for debug and release builds [duplicate]

Question

Does anybody know if it is possible, and if so how to link to one set of DLL's in a debug build and a different set of DLL's in a release build on a C# Project using Visual Studio 2008?

Answer 1

If you Unload the project file (context menu of the project) and then edit it, add a condition on the itemgroup for each build configuration holding the references:

<ItemGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCPU' ">
    <Reference Include="Common.Logging, Version=2.0.0.0, Culture=neutral, PublicKeyToken=af08829b84f0328e, processorArchitecture=MSIL" />
    <Reference Include="Elmah, Version=1.2.13605.0, Culture=neutral, processorArchitecture=MSIL" />
</ItemGroup>

After saving your changes, you can Reload the project from the context menu of the project file.

I don't think this can be done with default means of Visual Studio. One thing I could think of is to create some sort of "debug flag" and load the DLLs dynamically depending on that flag.
