I'm using MSBuild (via NAnt) to compile a bunch of VB.NET assemblies. Because these assemblies depend on COM Interop, I need to guarantee that they run in 32-bit mode on 64 bit OS's. I can get the executable assemblies to compile to 32-bit by changing the project in Visual Studio, but I'd really like to be able to force all of the executables to be compiled to 32 bit mode on the build server.
I've tried a number of command-line parameters to MSBuild with no luck:
What am I doing wrong? Is there some reference to the properties that MSBuild uses when compiling VB projects?

Here's why it matters. Simply put, a 64-bit processor is more capable than a 32-bit processor because it can handle more data at once. A 64-bit processor can store more computational values, including memory addresses, which means it can access over 4 billion times the physical memory of a 32-bit processor.
Visual Studio 2022 uses the 64-bit version of MSBuild for all builds.
MSBuild uses csc.exe as its actual compiler but knows where to find assemblies, references etc based on your solution and project files (these files are actually xml files).
To run MSBuild at a command prompt, pass a project file to MSBuild.exe, together with the appropriate command-line options. Command-line options let you set properties, execute specific targets, and set other options that control the build process.
According to MSDN, you're doing the right thing. Looks like /p:Platform=x86, but actually, maybe it's /p:PlatformTarget=x86.
Try to just invoke MSBuild directly with that parameter (make sure it's not an issue with your NAnt file. Look at the build output for the right build configuration (Debug / Release).

If the assemblies themselves are always going to be 32 bit, why not add the setting to the .vbproj file? That will take MSBuild out of the equation.
Just add the following line to the initial PropertyGroup in the .vbproj file
<PlatformTarget>x86</PlatformTarget> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
