[libRETS-users] Could not load file or assembly 'librets-dotnet' or one of its dependencies

[David R. Castranio]

I have problems streaming the photos into my application on .Net 4.0. It works on Visual Studio 2012 on my local machine, but on the Windows Server and IIS, the pictures will not come in. I tried to upgrade the version of .Net to the new 1.5.3 x64. It seemed like it might have been an issue with 64 bit version. When I loaded that version I get the following error

Could not load file or assembly 'librets-dotnet' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Did you register the DLL in the system32 directory?

This error indicates one of two things: you are mixing the x86 and x64
versions (e.g. putting an x64 version into x86 cache or vice versa);
you are running at a higher security level and this libraries need to
be self signed.

Thanks for your response, and thanks to the others who responded also.

I was thinking that the version we had been running with .Net 2.0 needed
upgraded to work correctly with .Net 4.0. The problem I have been having
with the picture imports failing on the host machine (but working on my dev
box) involves a Windows server and IIS with .Net 4.0.

Which version should I be using?

There was a problem with the SWIG generated bindings to dotnet that
needed to be fixed for .NET 4.0. This was done with SWIG 2.x+ and
librets rolled to that version in 1.5.2. So, 1.5.2 or 1.5.3 would be
the versions. You get more fixes with the 1.5.3 release. See http://code.crt.realtors.org/projects/librets/browser/librets/trunk/NEWS

Oh, do not use the MINGW versions unless you know what you're
doing ... not sure how they will react with .NET.
