NET Core files, and this means that you do not need to install anything on the client machine. I believe that this is a cool feature for people who need to run their applications on several machines and do not know what is installed. The support staff can benefit from it as well, for example when they need to test a specific version on the client machine. In this blog, I want to use one of our sample applications to demonstrate this feature. In the latest Visual Studio Preview there is no need to use a command anymore, and you can do this from the UI.
First, right-click on the project and then hit Publish, then select folder and click create. Once ready, save and click Publish. You can now go to the publish folder and get your app. I have tested the application on several machines, and it works without issues. The entire package is a large MB , but it contains all needed assemblies. It comes with a day free trial , giving you some time to explore the toolkit and consider using it for your current or upcoming WinForms development.
He joined Telerik after graduating from the Telerik Academy in Apart from work he likes outdoor activities and reading philosophy literature. You'll also be able to specify whether to include the pdb's, exclude certain assemblies, or extracting the assemblies on the fly. As far as I know, also unmanaged assemblies are supported. Currently, some people are trying to add support for DNX. Fody version 4. Current version: If they're actually managed assemblies, you can use ILMerge. For native DLLs, you'll have a bit more work to do.
Yes, it is possible to merge. NET executables with libraries. There are multiple tools available to get the job done:. In addition this can be combined with the Mono Linker , which does remove unused code and therefor makes the resulting assembly smaller. Another possibility is to use. NETZ , which does not only allow compressing of an assembly, but also can pack the dlls straight into the exe. The difference to the above mentioned solutions is that. NETZ does not merge them, they stay separate assemblies but are packed into one package.
NETZ is a open source tool that compresses and packs the Microsoft. ILMerge can combine assemblies to one single assembly provided the assembly has only managed code. You can use the commandline app, or add reference to the exe and programmatically merge. For a GUI version there is Eazfuscator , and also.
Netz both of which are free. Paid apps include BoxedApp and SmartAssembly. If you have to merge assemblies with unmanaged code, I would suggest SmartAssembly. I never had hiccups with SmartAssembly but with all others. Here, it can embed the required dependencies as resources to your main exe. You can do all this manually not needing to worry if assembly is managed or in mixed mode by embedding dll to your resources and then relying on AppDomain's Assembly ResolveHandler. This is a one stop solution by adopting the worst case, ie assemblies with unmanaged code.
The key here is to write the bytes to a file and load from its location. To avoid chicken and egg problem, you have to ensure you declare the handler before accessing assembly and that you do not access the assembly members or instantiate anything that has to deal with the assembly inside the loading assembly resolving part. Also take care to ensure GetMyApplicationSpecificPath is not any temp directory since temp files could be attempted to get erased by other programs or by yourself not that it will get deleted while your program is accessing the dll, but at least its a nuisance.
AppData is good location. Also note that you have to write the bytes each time, you cant load from location just 'cos the dll already resides there. For managed dlls, you need not write bytes, but directly load from the location of the dll, or just read the bytes and load the assembly from memory. Like this or so:. If the assembly is fully unmanaged, you can see this link or this as to how to load such dlls. The excerpt by Jeffrey Richter is very good. In short, add the library's as embedded resources and add a callback before anything else.
Here is a version of the code found in the comments of his page that I put at the start of Main method for a console app just make sure that any calls that use the library's are in a different method to Main. To expand on Bobby's asnwer above. You can edit your. See my answer for this question for further details. You could add the DLLs as embedded resources, and then have your program unpack them into the application directory on startup after checking to see if they're there already.
EDIT: This technique would be easy with. NET assemblies. With non-. NET DLLs it would be a lot more work you'd have to figure out where to unpack the files and register them and so on. Another product that can handle this elegantly is SmartAssembly, at SmartAssembly. This product will, in addition to merging all dependencies into a single DLL, optionally obfuscate your code, remove extra meta-data to reduce the resulting file size, and can also actually optimize the IL to increase runtime performance.
I believe it also has a command-line API so you can make it part of your build process. Say executable H loads assembly P dynamically and accesses it via interface IP defined in an separate assembly. To embed IP into H one shall need a little modification to Lars's code:. The trick to handle repeated attempts to resolve the same assembly and return the existing one instead of creating a new instance.
EDIT: Lest it spoil. NET's serialization, make sure to return null for all assemblies not embedded in yours, thereby defaulting to the standard behaviour. You can get a list of these libraries by:. When you have a lot of DLL it can be hard to manually include the one you need in your exe. The best method i found was explained by Wegged here on StackOverflow.
Copy pasted his answer here for clarity all credit to Wegged. It may sound simplistic, but WinRar gives the option to compress a bunch of files to a self-extracting executable. May be useful in some cases. In your xyz. I name the vbs script to match the. Unless you have a strict requirement to produce a hybrid assembly, I'd agree with MusiGenesis that this isn't really worth the trouble to do with C.
Generally you would need some form of post build tool to perform an assembly merge like you are describing. There is a free tool called Eazfuscator eazfuscator. You can add this into a post build command line with Visual Studio to merge your assemblies, but your mileage will vary due to issues that will arise in any non trival assembly merging scenarios.
You could also check to see if the build make untility NANT has the ability to merge assemblies after building, but I am not familiar enough with NANT myself to say whether the functionality is built in or not. There are also many many Visual Studio plugins that will perform assembly merging as part of building the application. Alternatively if you don't need this to be done automatically, there are a number of tools like ILMerge that will merge.
The biggest issue I've had with merging assemblies is if they use any similar namespaces. Or worse, reference different versions of the same dll my problems were generally with the NUnit dll files.

Fody - It is available as Nuget Pkg for best and easiest way to embed resources in your assembly. After adding it to the project, it will automatically embed all added references to your main assembly. When deploying this application, all the files must be deployed. However, there is a technique that you can use to deploy just a single EXE file.
NET Framework itself. The code should look something like this:. NET reactor has the feature of merging the assemblies and its not very expensive. Here is a tweaked version of the quoted code from Matthieu that doesn't require knowing the namespace to extract the code. For WPF, put this in the application startup event code. To make them available at compile time, I create a folder named ExternalDLLs and copy the dlls there and set them to EmbeddedResource as noted above. To use them in your code, you still need to set a reference to them, but set Copy local to False.
To get the code to compile cleanly without errors you also need to set using statments in your code to the namespaces of the dlls. Here is a little utility that spins through the embedded resource names and displays their namespaces in the output window.
Or doing the equivalent operation in Visual Studio: in your Publish Profile Settings, choose a target runtime you must have one selected to publish as a single file , then expand the "File Select Options" section and select "Produce Single File". Exact steps may vary with Visual Studio versions.
However using this approach I've had issues with running my unit tests, so I personally just select the option when publishing. Since all the other solutions are in C , and I needed this for VB.
