In my solution with several projects I am trying to change the Platform from Any CPU to x86. But x86 is not in the drop down. What do I need to do to be able to choose x86?

I need to change to x86 because of an System.BadImageFormatException error, as per this question: What causes System.BadImageFormatException when constructing System.Data.SQLite.SQLiteConnection

enter image description here

And, in a possibly related problem, the newest project in the solution is missing one of the configurations from the configuration drop down:

It should have a "Staging" configuration like all of the other projects, but does not. How do I add it?

EDIT:

If I choose the "New ..." option, then it asks me to copy from "Any CPU". If I copy from "Any CPU", isnt that just the same as using "Any CPU" in the first place?

Both the Configuration and Platform drop downs have a:

  • <New...>

option. In fact you have them circled in your annotated screenshots!

Use that option to create the "Staging" configuration and the "x86" platform for the corresponding project.

    Yeah I saw that but was not sure if it was the right option. x86 is not a new platform so why would I have to chose "new ..." to create an option for it? Same thing for the "Staging" configuration, it isn't new it already exists. – JK. Jun 18 '11 at 22:31
  • @JK: Those are **solution** configurations and platforms, not **project** configurations and platforms. They are different. It is **new** to the project that doesn't have it yet. – Rick Sladkey Jun 18 '11 at 22:34

    If I choose the "New ..." option, then it asks me to copy from "Any CPU". If I copy from "Any CPU", isnt that just the same as using "Any CPU" in the first place? See new screenshot in the question. And should I click the "Create new solution platforms" checkbox or not (I guess not) – JK. Jun 18 '11 at 22:57

    @JK: Copying copies the **other** settings that don't depend on the platform; it will still create an **x86** specific setting even when you copy from **Any CPU**. As far as creating solution configurations, it doesn't matter if the configurations already exist. If they didn't exist, you might or might not want to create them. – Rick Sladkey Jun 18 '11 at 23:13

I removed a solution platform and created it again with Create new project platforms check-box. It helped.

You can set project platform using the /platform compiler switch like below

/platform:string

Where the string can be either of x86, Itanium, x64, or anycpu (default)

csc /platform:x86 myprogram.cs

In case you want to achieve the same from Visual Studio then you can follow the below steps

  1. Open the Properties page for the project.

  2. Click the Build property page.

3.Modify the Platform target property.

See Here For more information on the same.
