nuget error - windows 10 - Anaconda Python 3.5.2 64 bit

from @mphielipp

Hi, I install this package. But when I run the project I get a runtime error . I have a Anaconda Python 3.5.2 64 bits install. I use the Nuget PAckage 3.5. I have tried to run it with x86, Any CPU, amd x64. Any suggestions?

Now I'm running x86. Crash in this line Py.GIL().
There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "Python.Runtime, Version=2.3.0.0, Culture=neutral, processorArchitecture=x86", "x86". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.

Windows 10

I installed it using the "MAnage Nuget Package" option in Visual Studio 2005.

I changed the "Target Platform Option" in project settings to x86. But I still get this runtime error in the same line:

An unhandled exception of type 'System.BadImageFormatException' occurred in Python.Runtime.dll

Additional information: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

@mphielipp are you really using VS 2005??? Your anaconda is clearly 64-bit, hence you need to select x64 target in VS. Which nuget pythonnet package did you install? There are many versions of them.

What .NET runtime are you targetting?

What do these commands show?

where python
python --version

I see the issue, nuget does not switch automatically the version of package (x86 and x64) depending on the architecture:

@denfromufa looks like you arrived to the same solution we did. We got it fixed by manually updating the dll reference to the 64bit version. I don't know how other libraries deal w this though, dllexport and nunit may have some solution for this.

@denfromufa i would like to confirm my understanding on this issue.
Do you mean that currently, the System.BadImageFormatException error still have not been solve if we downloaded Pythonnet from NuGet ?
