I have to call functions from a custom dll from BizTalk orchestrations (similar to this solution Call a custom .NET component from BizTalk 2006). The dll calls functions of a third party dll, which uses some other third party dlls (we are using to communicate with a legacy system).
The article Global Assembly Cache Tool (Gacutil.exe) says that my best bet would be to "include" the referenced dll into the dll I put into the GAC, but I don't know how to do this from Visual Studio (2010).
Any ideas to get this work ?
It looks like putting them into the system PATH solved this problem.

Backgroud:
I am in the process of migrating a console application to be part of our existing web API project. All development work is done on Visual Studiod 2015 (with IIS Express). The application uses few third party datasource api DLLs to grab data from that datasource. All these DLLs are managed by our internal nuget package sources.
Issue:
Now the console application runs fine and can load up the those DLLs. I copied across the logic into my web project and added the DLLs via nuget. Solution builds but got the following error when starting up the web project:
Could not load file or assembly 'ABC.DLL' or one of its dependencies. The specified module could not be found.
Where ABC.DLL is one of the third party DLLs.
I have done the following:
Confirm ABC.DLL is in the bin folder of my web project
Changed target build platform of my web project to be x86 and unchecked "Use 64 bit version of IIS Express for websites and project" setting in VS2015 (the third party dll is 32-bit)
Ran dumpbin.exe on ABC.DLL's dependency and got XYZ.dll,MSVCR120.dll,KERNEL32.dll,MSVCP120.dll,mscoree.dll
Regarding to the last step, those dlls were all missing in the bin folder (but the last 4 DLLs should be in system32 win directory so shouldn't matter?)
As for XYZ.dll, it is another third party library and is located on C:\Program Files (x86)\XYZ\ folder. I manually copied it across to the web project bin folder (in fact copied across all Dlls inside XYZ folder) and still get the same issue.
Questions
What am I missing here? The console app obviously can load ABC.DLL but the web project can't. Appreciate it if you can tell me what to check next.
The error message from start up web page is not very useful, is there a way to find out where the web project is trying to load the third party DLLs?
Thank you in advance!
Simply adding external DLLs to your Bin folder is not a great idea. Files can disappear from this folder for various reasons, such as your team members deleting a seemingly useless DLL, or through Visual Studio clearing it. Also, the output DLLs from referenced projects in your solution, would end up there, and are replaced every time you build your project.
What you should do for third-party DLLs, is create some "dependencies" folder in, or close to, your project, and stick the DLLs in there. Then you should right-click on the project, select Add Reference, browse to that new "dependencies" folder, and add a reference to the DLL that way. This is similar to the way NuGet works; it keeps DLLs in their respective folders inside the packages folder, and adds references to those DLLs.
I finally found the issue and thanks for all the help, I had to disable shadow copying in VS (mentioned in 64 bit managed assembly with unmanaged dependencies not loading in IIS / ASP.NET MVC 4).
When i Publish my project i m getting this error:
error CS0009: Metadata file
'D:\home\site\approot\packages\Microsoft.ApplicationInsights\1.1.1-beta\lib\net45\Microsoft.ApplicationInsights.dll'
could not be opened -- Invalid COR20 header signature.
(I m using asp.net core 1)
Did Someone knows or has experienced the same problem?
Thanks
This problem can occur when you have added a third-party DLL to your application and have not properly added it to your compiler’s project file or references list.
If that's the case this might work:
Open your project in Visual Studio .NET. Make sure the DLL exists and has been properly added to the reference list. If you are using VBC or CSC to compile your project, check your application’s CompileApplication.rsp file to make sure the DLL is in the /references list like the other DLLs.
Your DLL may not be compatible with .NET or with .NET’s 32-bit mode. Ensure that your DLL is .NET compatible.
If your project still won’t compile properly, try switching your application’s compiler selection in Iron Speed Designer’s Application Wizard from 'vbc.exe' or ‘csc.exe’ to Visual Studio .NET or vice versa. Using Visual Studio .NET will take longer to build than .NET’s VBC or CSC built-in compilers, but Visual Studio .NET will resolve all of the references properly without having to change your application’s CompileApplication.rsp file.
Am I doing this right? I've got many, many separate ASP.NET webforms projects which reference the same main library which contains many tool methods. When I change something in that library, I don't know of a way to make sure that these projects get the updated version of the library. Does auto-refresh detect changes in references even if you don't open the project in Visual Studio? Or does IIS know when a reference has changed and will recompile the project?
Assuming the DLL file is binary compatible (changing an existing method signature is the easiest way to break compatibility) all it comes down is that the newest DLL is in the \bin\ folder. If the site is running it would need to be restarted to pick up the DLL being replaced.
If this is a project reference in your solution, building just does all of this for you.
If this project is outside of your solution, you really should look into using Nuget to distribute this shared project. Even if you only distribute it to yourself. You do not need to host the package publicly on nuget.org
is there a way for msdeploy to figure out reference of reference?
for example, i have project B that references project A that references TFS assemblies.
On my dev machine, TFS assemblies are GACed with Visual Studio installation, but my server doesn't have VS installed so it isn't GACed.
msdeploy doesn't seem to understand that it has to copy both assembly A and TFS assemblies that assembly A references.
I believe it is by design that VS ignores 'CopyLocal' if the assembly is GACed and i know that i can work around it by adding the assembly directly into the project but i am looking for more automatic way.
You should use the TFS API Nuget package to reference these assemblies instead of the GAC.

Is there a way to use BTSTask to add a non dll assembly to a BizTalk application? If I use the "AddReference" command it seems like it only allows you to add BizTalk assemblies?
Yes you can add any .NET assembly as resource and package it in the MSI. See this topic http://msdn.microsoft.com/en-us/library/aa561819(BTS.70).aspx
