Question

I have ws2008 x64 with vs2008.

When I set my vs to x64 (because I have 64bit dlls) and run compilation sgen says that

An attempt was made to load an assembly with an incorrect format

VS takse sgen from
C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\

and I think that it should take it from
C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\x64\

when i take 64bit version of sgen and put it into C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\ (replace 32bit version). I was able to compile.

What should I do to point to the correct version of sgen under vs.

Can I somehow configure solutinon platforms for one project to point to the correct sgens (for x86 to 32 bit and for x64 to 64 bit sgen version)?

Answer 1

This is the best answer I could find: Conditional Post-Build Event Command for x64 sgen, a blog post by Michael Hanes.

Use a post build event, that conditionally checks if the 64 bit SGEN is installed, and use it when needed:

REM Use the 64-bit sgen from the Win 2008 and 
REM .NET 3.5 SDK in a 64-bit dev environment
REM ProgramFiles variable is set to 
REM 'Program Files (x86)' in a x64 environment 
REM Processor_Architecture variable returns x86 
REM in both an x86 and x64 environment within VS.

if /I "%ProgramFiles%" == "C:\Program Files" (
set SgenToolPath="C:\Program Files\Microsoft
SDKs\Windows\v6.0A\Bin\sgen.exe"
) else (
set SgenToolPath="C:\Program Files\Microsoft
SDKs\Windows\v6.1\Bin\x64\sgen.exe"
)

%SgenToolPath% /compiler:"\"/keyfile:$(ProjectDir)
MyKeyFile.snk"\" /force "$(TargetPath)"

This is intended to be a replacement for the “Generate Serialization Assemblies” dropdown setting for “On” for a given Visual Studio project.
