CLR/CLI linker fails with error LNK2022 - Custom attributes are not consistent

Environment: Visual Studio 10, CLR/CLI Class Library project, built with Platform Toolset v100, targeting framework version v3.5.

I am aware that this question was already asked here, but I did not find an answer that solved the problem for my case, so bringing this up again.

While building a CLR/CLI Class Library (DLL) project the linker is failing with the following errors:

MSVCMRT.lib(managdeh.obj) : error LNK2022: metadata operation failed (80131195) : Custom attributes are not consistent: (0x0c0000f7).
MSVCMRT.lib(managdeh.obj) : error LNK2022: metadata operation failed (80131195) : Custom attributes are not consistent: (0x0c0000fb).

Solution

  • Another thing I learned on the way is that you cannot mix values of Platform Toolset and Target Framework Version.

    The possible combinations I found where:

    .NET 3.5 or less:

    • Platform Toolset: v90, which will use Visual Studio 2008 runtime binaries,
    • TargetFrameworkVersion: v3.5 (or less),
    • In the preprocessor you can have _WIN32_WINNT defined (e.g. _WIN32_WINNT=0x0500)

    .NET 4.0 or higher:

    • Platform Toolset: v100, which will use Visual Studio 2010 runtime binaries,
    • TargetFrameworkVersion: v4.0 (or higher),
    • In the preprocessor you must not have the '_WIN32_WINNT=0x0500' defined

    How to define these values:

    1. Platform Toolset – find it under: Project settings | General,
    2. TargetFrameworkVersion - Unload the project, right-click on the unloaded project and select 'Edit'. Once the '*.*proj' file is open, modify the following line: <TargetFrameworkVersion>v3.5<TargetFrameworkVersion/>
