Replied by support on topic Unnecessary warnings messages are thrown in code compile, isolate these warnings

Hello.
The messages are well known and should be ignored. There is nothing that can be done about them (except suppressing them for msbuild).

Explanation:

QuickOPC contains some assemblies written in C++/CLR. Such assemblies cannot be compiled for "AnyCPU". They need to target a specific processor bitness - either x86, or x64. We thus have the same assembly compiled for both. And in the runtime, we always load just the correct one.

The compiler, however, has no way of knowing what happens in runtime. If you compile the whole project for x86, the assembly for x64 will look "wrong" to the compiler, even though it never gets loaded. Vice versa, if you compile for x64, the assembly for x86 will look wrong to the compiler. If you compile to AnyCPU, which is most common, BOTH will look wrong to the compiler. But it is all perfectly fine.

Best regards

our applications are completely warnings free, we need to resolve these and isolate in our build process, please can you check this.
