I have made a website with Visual Studio 2010. I have a simple Fortran .dll that I want to call from my project. I have added this DLL in my project but when I run it I get the error:
Unable to load DLL 'Dll1.dll': The specified module could not be found.
which probably means that the DLL can not be found. Do I have to add the .dll somewhere specifically or add the location of the DLL to the code?
Assuming that Dll1.dll is the DLL that is one that's referenced, make sure that in Solution Explorer, this DLLs properties are set to Copy Always.
Right-click the dll file, click on properties, then in the properties pane below the solution explorer, set "Copy to Output Directory" to "Copy Always".

I've got an ASP.NET MVC 5 project with a reference to a class library project which is using OpenXML installed via NuGet.
Install-Package DocumentFormat.OpenXml
It all works on my development machine. But when I publish the OpenXML assembly (DocumentFormat.OpenXml.dll) is no where to be found on the server.
What do I need to do get it included when I publish?
You should set copy to local to true for that assembly file. To do that, right click on the reference file (which is showed in your image) and then click "properties". In the showed window you can find it.
Try removing any instance of DocumentFormat.OpenXml.dll from your workstation's Global Assembly Cache (GAC).
Open the GAC root in Windows Explorer (Win 7: %windir%\Microsoft.NET\assembly)
Search for OpenXml
Delete any appropriate folders (or to be safe, cut them out to your desktop in case you should want to restore them)
remove the dll and add is a nuget:
Install-Package DocumentFormat.OpenXml
Currently I'm playing with sitecore 7. I followed this blog to setup my visual studio with the sitecore.
Everything is fine until when I tried to create a sc:placeholder on the aspx.
It throws this error regardless whatever sitecore control I have tried to insert:
Error 180 The type or namespace name 'Web' does not exist in the namespace 'Sitecore' (are you missing an assembly reference?)
C:\inetpub\wwwroot\abc Sc7\Website\layouts\Customized\MainLayout.aspx.designer.cs
I tried to create a placeholder using code behind, no error was thrown.
I have tried to create an empty web application project. And added a reference to only Sitecore.Kernel.dll
I created a dummy page to test out the reference to the dll thing.
It still throws the same errors.
I know the blog mentions it, but have you added a reference to the "Sitecore.Kernel" DLL in your project? Open your references folder and ensure that there is not a problem with the reference.
Make sure your project is using .net 4.5 (you will need to use something other than VS2010)
After default sitecore installtion Sitecore.Kernel assembly is placed in bin folder. Maybe you used 'Clean project' and after this operation your assembly was deleted. Please check if this assembly is present in bin folder. It should be loaded by IIS automatically from bin folder, even if you have wrong reference in you csproj file.
When I start new project I always move dlls from bin folder to other folder, and put references to this files in csproj, so when I run clean project (or clean solution from VS) i have empty folder (only one file is present - *.lic file).
The *.dll.refresh file tells visual studio about the class library location but whenever I delete it the application still works in debugging mode.
Why is this? Is the location not needed?
Because that's only a pointer to the referenced DLL.
It is used to copy the DLL to the bin location, but if you already copied the DLL, then deleting the .refresh file won't affect Visual Studio
If you delete the DLL from the bin folder and the _*.refresh_ file then you would get compilation errors if you try to access the types defined in the referenced DLL
dll.refresh files gives the path of the DLL in question to tell visual studio where to find it. They will be created each time you add a reference to the project.
They normally appear when you are using a project type that does not create a standard Visual Studio project file, as normally paths to referenced DLLs would go in there.
Their role ends once DLL gets loaded in your project. Hence you will not get any error
when you delete *.dll.refresh files from your project.
I've got a question about something that's just been irritating me.
A colleague and I are building a support framework for our current client that we want to reference in other projects.
The DLL we want as a reference in our project would be an external reference. We're adding it by doing "Add Reference...", then browsing to the location of the .dll. What I want Visual Studio to do is only add the .xml, .pdb, and a .dll.refresh file, but instead it copies the actual .dll (and .xml and .pdb) into the bin.
When we rebuild the framework project, the other project that uses its .dll gets all out of whack until we drop and re-add the reference. Everything I've read online says that VS2008 is supposed to create the .dll.refresh files for you, but it never does.
Any ideas? Am I missing something or doing something wrong?
At this point I'm ready to add a pre-build event to simply copy the framework .dll into my bin, but the .refresh file seems like less of a hassle if it would just work.
Thanks.
UPDATE:
This SO post describes the actions that are supposed to be happening with the refresh files.
So it turns out that .refresh files are only created for Web Site projects, not Web Application projects.
The problem stems from Visual Studio having trouble deleting lock files for DLL references over 64kb, a problem supposedly fixed in VS 2010.
The current workaround is to close and reopen the solution or to unload and reload the project containing the references.
If the Projects are in the same Solution and you add a "Project Reference" that should solve your problem.
You can try to add references another way.
Add reference
Choose tab Browser (Not tab Project)
Choose *.dll that you need
I have tried it and been successful.
If you choose tab Project --> there are no *.dll.refresh added
How do you attach a DLL to a asp.net site? I want to be able to debug and edit the DLL without having to keep replacing the reference in my asp.net site. I checked attach to process but didn't see the worker process. I am using asp.net, IIS 7.
Just put it into /bin folder of your web application.
OR
Add reference to this .dll by right clicking on References > Add Reference > Browse > Select your .dll file and lick OK.
Then set it's "Copy Local" property to "True". This way .dll will be copied into /Bin folder each time you build application.

Using Visual Studio you should create a solution that has your website as a project and the DLL (code) as another project. Make a reference in the website project to the DLL project and it should update it automatically.
If you are not using the web application model and just the website model you could just have your DLL project output to your website's /bin directory directly. That will update the DLL in the website/bin folder whenever you build your DLL project.
If you want to edit the dll, open that project up in a second instance of Visual Studio and treat it like you would for any other project.
Set the reference in your /bin folder to the debug dll that the second Visual Studio creates.
I'm assuming you have Visual Studio...
If you're just trying to add a dll, you can add a reference to it by right clicking on your website node and choosing "Add Reference..." .
You will be able to debug the dll if you have its pdb along with it (to load the symbols from). You will NOT be able to edit the dll.
If the dll is in fact another project you have the source code for, just add the project to your solution, and from your website project add a reference from the "projects" tab. VS should add a reference and dependency so that it keeps the dll updated when you change code in your dll project.
