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

Question

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

Answer 1

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: v3.5
