Run AnyCPU as 32-bit on 64-bit systems

问题

We are using a Third-Party assembly that seems to be compiled as AnyCPU.

However, we have a number of installations of our application where this leads to problems. This Third-Party assembly makes use of the oracle dataaccess library, and will not work on 64-bit machines where only a 32-bit oracle client is installed.

Installing a additional 64-bit oracle client would be possible, but also expensive (takes a lot of time, many machines have to be updated etc.)

Is there a way to force a AnyCPU .Net assembly to run as 32-bit without recompiling?

回答1:

Have a look at CorFlags.exe.

Example (set 32BIT flag):

corflags [path]\[YourAssembly.exe] /32Bit+

回答2:

Assuming that you are building the .EXE that has a reference to a AnyCPU third party assembly you need to build your project as x86. This project can reference AnyCPU assemblies but being marked as x86 it will run as a 32 bit process on both 32 bit and 64 bit Windows.
