I am trying to include some reference files in Wix# managed project using DefaultRefAssemblies.Add method:
ManagedProject project = new ManagedProject();
project.DefaultRefAssemblies.Add("FontAwesome.Sharp.dll");
project.DefaultRefAssemblies.Add("protobuf-net.dll");
project.DefaultRefAssemblies.Add("Newtonsoft.Json.dll");
project.DefaultRefAssemblies.Add("ManagedOpenSsl.dll");
project.DefaultRefAssemblies.Add("ssleay32.dll");
When I try to build a MSI I get an error. The problem happens to be in loading of ssleay32 assembly (part of OpenSSL). When I exclude this file, the build succeeds. Can you please help me understand the exception? The target framework of the Wix# project is .NET Framework 4.8.
Unhandled Exception: System.BadImageFormatException: Could not load file or assembly '361984 bytes loaded from WixSharp, Version=1.15.0.0, Culture=neutral, PublicKeyToken=3775edd25acc43c2' or one of its dependencies. An attempt was made to load a program with an incorrect format. ---> System.BadImageFormatException: Bad IL format.
Wixsharp supports .net assemblies compiled for:
Platform x86
Managed assemblies (Not native)
Target framework 3.5
So, make sure "ssleay32.dll" has 3 requirements above. Every ssleay32 assembly i have found was native (unmanaged).
Workaround in case of no luck with:
You can try to save ssleay32.dll to embedding resource file and before "ManagedOpenSsl.dll" types usage you should load dll in the memory. Load unmanaged assembly
Good luck!

What I'm trying to do
I'm trying to create a library (Arduino.dll) to interact with my Bluetooth device from a laptop (Windows 10). This library is intended to be used by a desktop application.
To achieve that, I had to reference both Windows.winmd and System.Runtime.WindowsRuntime.
What's working
I did write the library and tested it on a console application which was on another project in the same solution. To make it work, I had to reference the project and Windows.winmd in the test project. Note that this test project is used to test all of my libraries, so it is heavily manipulated and I tinkered with the settings a lot for years.
What's not working
I finished to write my dll, and wanted to use it in my desktop application. Therefore, I referenced both Arduino.dll and Windows.winmd as in my test project, expecting to work the same way. Sadly, on running the application, I got a "dll not found" when instantiating a class for Arduino.dll :
An unhandled exception of type 'System.IO.FileNotFoundException' occurred in LuxAFX4.exe
Additional information: Could not load file or assembly 'System.Runtime.WindowsRuntime, Version=4.0.10.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.
Strange, but well, I tried to reference the (same) System.Runtime.WindowsRuntime as in Arduino.dll but no luck, I now got an even weirder error :
An unhandled exception of type 'System.BadImageFormatException' occurred in LuxAFX4.exe
Additional information: Could not load file or assembly 'System.Runtime.WindowsRuntime, Version=4.0.10.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. (Exception from HRESULT: 0x80131058)
During my search for a solution, I understood that I shouldn't try to load this "reference library" and if it is not found, it must be because it is not installed on the system. But then, why would it work in my test project?
Another thing I may have understand, is that if my library doesn't expose members of referenced 'sub'-libraries, they won't be needed when referencing my library. Should I try to 'hide' all references? If so, is there a way to catch all exposed members? Source : How to to avoid referencing a dll's referenced dll
Side note : I use C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETCore\v4.5.1\System.Runtime.WindowsRuntime.dll and C:\Program Files (x86)\Windows Kits\10\UnionMetadata\Windows.winmd.

After some more research, and with the hint given by Hans Passant, I finally understood that I had chosen the wrong System.Runtime.WindowsRuntime.dll to start with. Changing it to use C:\Windows\Microsoft.NET\Framework64\v4.0.30319\System.Runtime.WindowsRuntime.dll instead in both the project with the DLL and the project using it, resolved my problem.

I'm having error when running WPF application with reference to C:\Program Files\Affectiva\Affdex SDK\bin\release\Affdex.dll
Exception:
Could not load file or assembly 'Affdex, Version=3.1.1.419, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format."
The WPF application is running under .Net Framework 4.5 and I'm running SDK version downloaded as AffdexSDK-3.1.1-419-win64.exe
According to this Affdex.dll depends on affdex-native.dll and loads it in runtime. Make sure that the latter is accessible to your program by adding it to your %PATH% variable or by adding it to your visual studio project. See example in AffdexMe source code.
I am now dealing with a existing solution in VS2012.
Now I can execute it in debug mode but cannot trigger some of the function with the error
"Exceptions: System.Exception: Could not load file or assembly
'Interop.Score, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=5ce8a8a190705d24' or one of its dependencies. The
located assembly's manifest definition does not match the assembly
reference. (Exception from HRESULT: 0x80131040)"
After finding some of the suggestion, some of that suggest me to compile the solution in 32-bit (x86).
However, when I tried to rebuild with the target platform x86, another type of error occur and I even cannot run in debug mode, the error:
Referenced assembly 'GenCode128.dll' is not a valid assembly C#
P.S. GenCode128.dll is one of the error .dll, there is at least 2 of this kind of error.
I cannot search any successful way to solve this problem, appreciate for any help.
You can use a decompiler such as DotPeek (https://www.jetbrains.com/decompiler) to look inside your DLL and see if it is a valid .NET DLL -- and which version of .NET it is. It could be an x64-compiled assembly; in that case you cannot use it on a 32-bit system or from a 32-bit-compiled .NET assembly.
You can try installing it from NuGet.
I've created a NuGet package for GenCode128.dll here: https://www.nuget.org/packages/GenCode128/
Also the source can be found in GitHub: https://github.com/SourceCodeBackup/GenCode128
I'm trying to use ILMerge to create a single executable that uses Windows Azure SDK 2.0 including the Microsoft.WindowsAzure.ServiceRuntime.dll, which I added manually because I couldn't find any NuGET package that contains it.
I'm using the following command line on a VS2012 post-build event:
/wildcards /targetplatform:"v4,C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0" /log:ILMerge.log /closed Output.exe *.dll /out:Executable.exe
However, I'm getting the following error in ILMerge.log, even though the output window reports no issues at all after building:
The assembly 'Microsoft.WindowsAzure.ServiceRuntime' was not merged in correctly. It is still listed as an external reference in the target assembly.
An exception occurred during merging:
ILMerge.Merge: The assembly 'Microsoft.WindowsAzure.ServiceRuntime' was not merged in correctly. It is still listed as an external reference in the target assembly.
at ILMerging.ILMerge.Merge()
at ILMerging.ILMerge.Main(String[] args)
And then the executable throws the following exception when opened:
System.Reflection.TargetInvocationException: Exception has been thrown by the
target of an invocation. ---> System.IO.FileNotFoundException: Could not load file
or assembly 'msshrtmi, Version=2.0.0.0, Culture=neutral, publicKeyToken=31bf3856ad364e35'
or one of its dependencies.
I have also tested the same output without merging and it works fine.
What am I missing here?
It would seem like this cannot be done, or at least not how I want it done.
Microsoft.WindowsAzure.ServiceRuntime.dll seems to have a dependency on the native library msshrtmi.dll. This means that ILMerge cannot handle it, since unmanaged code cannot be merged with managed code.
According to these two questions there is a way to work around this problem, but it involves packaging the msshrtmi.dllas a resource and unpacking it when it's needed. I feel it's kinda hacky.
So I guess I'll just have to do what I should have done before: remove all references to Microsoft.WindowsAzure.ServiceRuntime.dll from the project that builds the merged, non-Azure version of my WCF service. This might involve using some IoC container and doing some heavy refactoring, which is why I was trying to avoid it at this stage.
Hey guys (and gals) I'm having a problem using Assembly GetExportedTypes() in .NET 4.0. The same code is working perfectly in a project targeted at an older .NET version.
NOTE: *The code works for local assemblies but when trying to open them off a network drive it does not work, that is my problem... It looks to be loading the assembly, but it claims it can't find it when using GetExportedTypes(). Again if I open a dll off my machine it works, this error only occurs with dlls located on network drives *
EDIT: The error is thrown on GetExportedTypes
The Code:
Assembly assembly;
Type[] t;
assembly = Assembly.LoadFrom(dllPathOpenFileDialog.FileName.ToString());
t = assembly.GetExportedTypes();
The Error:
Could not load file or assembly '*..***.***.****, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

The way certain security policies are handled was changed in .NET 4.0. This article should provide some background.
