Environment
- Pythonnet version: master
- Python version: 3.7
- Operating System: Windows 10
- .NET Runtime: .NET 4.8
Details
- Describe what you were trying to get done.
Calling .NET methods from Python
- What commands did you run to trigger this issue?
Given a class like the following, any value you pass for address to the first MethodA will cause the exception underneath, it looks like because when needsResolution is true, the Converter will see the the value as an Int32 in GetTypeByAlias since in 3.7 there is no distinction between int and long anymore.
public class MethodResolutionInt
{
public IEnumerable<byte> MethodA(ulong address, int size)
{
return new byte[10];
}
public int MethodA(string dummy, ulong address, int size)
{
return 0;
}
}mri = MethodResolutionInt()
data = list(mri.MethodA(0x1000, 10))
assert len(data) == 10
assert data[0] == 0
data = list(mri.MethodA(0x100000000, 10))
assert len(data) == 10
assert data[0] == 0- If there was a crash, please include the traceback here.

I have a PR almost ready with A solution to the issue, but it may not be the correct solution.
