Build C# project with msbuild.exe doesn't overwrite project target platform configuration?

Question

I have a c# project and in the solution, the platform target is AnyCPU. While I have a build program that will daily build this solution and it uses msbuild.exe. The command likes:

MSBuild D:\my.sln /p:Configuration=Release /p:Platform=x86 /t:rebuild ....

Here I specify the compiled platform should be x86.

I my opinion, the msbuild.exe should overwrite solution configure and the output should be x86 exe instead of anyCPU type.

I try these codes into this project:

        PortableExecutableKinds peKind;
        ImageFileMachine machine;

        Assembly.GetExecutingAssembly().ManifestModule.GetPEKind(out peKind, out machine);

The test result suggest, the exe is AnyCPU mode (ILOnly), not what expected. In such condition, how can i know my program it compiler by x86 or x64, by code?

Thanks. Li

I prefer not to build the .sln file but use use a little build script with msbuild.exe

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Deploy" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">


<Target Name="BuildProjects" >

    <ItemGroup>      
        <BuildProjectsInputFiles Include="**\MainProject\*.??proj" />
        <BuildProjectsInputFiles Include="**\AnotherProject\*.??proj" />
    </ItemGroup>

    <MSBuild Projects="@(BuildProjectsInputFiles)" Properties="Configuration=$(Configuration);OutputPath=$(MSBuildProjectDirectory)\Deploy\bin\%(BuildProjectsInputFiles.FileName)">
        <Output TaskParameter="TargetOutputs"
                ItemName="BuildProjectsOutputFiles" />
    </MSBuild>

</Target>

</Project>

Now I use msbuild with this call

msbuild.exe build.xml /p:OutputPath=bin\Debug;Configuration=Release;Platform=x86 /target:BuildProjects

And that works

Thanks SchlaWiener. I just update my post. I can't modified the build scripts because that out of my territory. So my question shrinks to how can i get x86/x64 info by code? After testing, if i compiler with /p:Platform=x86 or /p:Platform=x64, the dll actually is different (I try to dynamically load x86 .net dll inside x64 compiled program, an error happen) regardless both peKind = ILOnly.

Check IntPtr.Size which should be different for x86/x64 processes.
