I have a Web Site and Class Library built with ASP.NET 5. The Class Library depends on an set of external files (XML, EXEs, etc.). Those dependencies are added as part of the project and visible in the Solution Explorer of Visual Studio.
My Web Site has a dependency on the Class Library. When I build the Web Site, I would expect the dependencies of the Class Library to be copied to the Web Site, but they aren't.
The Build Action (Copy always, Copy if changed) appears to be gone with ASP.NET 5. How do I make sure that dependencies other then the DLL of the Class Library itself gets copied to the Web Site project?
First thing first, they won't be in src/yourProject/bin/Debug. Those have been moved to the artifacts folder.
Also, your project by default will not output DLLs. This is mainly due to performance reason but if you need your DLL to publish your application, check your project properties. In the Build section you should have an option called Produce outputs on build. Tick that and bingo.
You have your dlls. Most of the time (aka: while coding), you won't need them since they will always be recompiled in memory.
You need to manually add a pre/post build step in project.json

.Net Core projects do not put the reference DLLs from the nuget packages in the bin folder. Is there a way of any properties that helps in doing that?
It's needed for some third party tools to understand the reference DLLs.
.NET Core, unlike .NET Framework, can resolve assemblies from half a dozen locations. This includes the NuGet cache, servicing cache, runtime store, local app directory, and shared framework folder. During development, these are typically found in the NuGet cache (%USERPROFILE%.NuGet\packages) This makes it unnecessary to copy referenced assemblies to the build output folder (bin) until you publish your application. For more details on how that works, see https://github.com/dotnet/core-setup/blob/master/Documentation/design-docs/corehost.md
You can force the SDK to copy assemblies to your build folder by setting the proper below, but it increase disk use and build time.
<CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>
Or you can use the deps.json and runtimeconfig.json file to locate required assemblies.
I downloaded two DLLs (libgit2sharp.dll and git2.dll) from this site.
After that I successfully added Libgit2sharp.dll by add reference in my .NET Windows application. Now when I add git2.dll by add reference in my .NET Windows Application, it gives an error:
a reference to 'C:\User\nitesh\git2.dll' could not be added please make sure that the file is accessible and that it is a valid assembly or COM component
Can anyone please help me understand the problem?
I downloaded two DLLs (libgit2sharp.dll and git2.dll) from this site.
First off, this is not a distribution channel that the libgit2/libgit2sharp team has anything to do with.
Install as a NuGet package:
Official releases are available as a NuGet package if you prefer to download pre-built sources. See this post which explains how to install the NuGet Package Manager in Visual Studio.
This is the easiest way to make LibGit2Sharp available to your project.
Build from the source code:
You can download the source code and build the C# code into LibGit2Sharp.dll from https://github.com/libgit2/libgit2sharp, which includes the pre-built version of git2.dll which works for the particular version of the C# code.
Easiest way to build the assembly is by launching the build.libgit2sharp.cmd. This will create a Build folder into which you'll find the LibGit2Sharp.dll and a NativeBinaries folder with the native binaries.
Now when I add git2.dll by add reference in my .NET Windows Application, it gives an error
As for the error message, it sounds like you're trying to add the git2.dll to the project as though it were a CLR/.NET assembly. It is however built from C and isn't something VS is going to do anything useful with. You do not need to add it to your project.
It does need to be available for libgit2sharp to load. The following graph depicts the folder hierarchy that libgit2sharp expects
NativeBinaries+
|___amd64+
|___git2-{shortsha}.dll
|___git2-{shortsha}.pdb
|_____x86+
|___git2-{shortsha}.dll
|___git2-{shortsha}.pdb
Note: This folder structure will be dynamically created in your project output folder if you installed LibGit2Sharp as a NuGet package. However, if you built the project from the source code, you'll have to copy this folder structure as part of your project build process yourself.
I'm not very experienced with deploying applications and i'm having an issue with my very small screen scrape application.
I use a project that handles all screen scrapes and i just call the functions from the dll(on dev machines at least). When i reference that dll from the directory, it works fine on my machine but installing and launching on another machine without the project crashes it immediately when it tries to access the class to instantiate the screen scrape object.
Perhaps my assumption of dll is incorrect but doesn't having the dll mean it incapsulates all the classes/references/etc in that project so it can be used elswhere without having to lug the whole project with it?
What could be going on with this dll?
The dll assembly encapsulates the project, but not its references. Anything that the project needs to reference must be available in the new environment as well, whether in the GAC (global assembly cache), the local directory, in a reference path, or wherever.
If you are using Visual Studio 2010 or earlier, you can use Setup Projects to nicely gather all necessary references and package them into an install package for you. There may still be complications that you will need to troubleshoot sometimes, but it simplifies your deployment effort. In Visual Studio 2012 and later, Setup Projects were dropped, but there are other options, like WIX and Install Shield. And that is a whole other topic with plenty of Q&A on this site.
I need to compile my web site, is it possible without converting to a web project first?
I think he wants to "protect" his code for any deployment.
If this is a .Net project you can try hide some code using codebehind components in ASP.NET.
Here is an small tutorial about it:
http://asp.net-tutorials.com/basics/code-behind/
For older projects you may have to build a cgi binary application, but as already mentioned here, add some more details to specify your problem.
I think you want a VS Web Deployment project. This exists as a separate project in your solution but can compile and copy the existing web project to a different directory.
There's a reasonable write-up of it on this blog with step-by-step instructions. You'll need to download and install the new project type separately though (2008, 2010)
Questions:
Are XAP files self-contained?
Do they link in all DLLs I have referenced in the project?
If I need to distribute my app, is all I have to do is hand someone the XAP file?
By default, yes. For alternatives, see answer 3.
By default, all except the core DLLs installed by the runtime; it will contain anything from the SDK, Toolkit, 3rd party controls, or your own libraries.
By default, yes. However, there is an option as of Silverlight 3 to package certain assemblies (for example anything from the SDK) into separate ZIP files, which are downloaded separately. In Visual Studio, look in the project properties for a checkbox called "Reduce XAP size by using application library caching." This option toggles whether to create/use the ZIP files or not. Enabling the ZIP option allows multiple Silverlight apps to share the dependency on the ZIP files, so that instead of packaging everything into the XAP every time, you just download the ZIP for one app, and it's saved in the browser cache for other apps.
As for the general contents of the XAP file, there are 2 important bits:
Foo.dll - your project's main assembly (renamed as appropriate)
AppManifest.xaml - describes the requirements for you app, e.g minimum runtime version required, the entry point into Foo.dll, and other settings, including Out-of-browser settings, or whether to use the Library caching feature mentioned above.
Anything else is just content used by your app.
Silverlight XAP files can be tricky if you're using anything other the the core silverlight assemblies (eg. SilverlightToolkit).
XAP files are just zip files - open one up and take a look. They are self contained to the extent that any custom/extra dlls are included - the standard Silverlight assemblies will be installed when a user installs Silverlight.
References to dlls are required in the .proj files for every assembly that will be used. Ie. unlike other project types, if one project references another project, both projects need to reference all dlls used by either project.
You should be able to just hand someone the XAP file if you want - but Silverlight was designed to be used in browsers, so you will need to include the generated test page at least. The best, and most useful, is to provide a publicly accessible web page that hosts your silverlight app.
HTH.
Even though this question is already answered, i'm going to throw this one in too because it hasn't been mentioned yet.
You mention that you are using SL4 - if you are running out of browser (OOB) then you can just ship the XAP file, and use sllauncher.exe (2) to "install" it to the client machine. As part of that install you can also specify where updates are to be sourced from, which is important for when you find bugs or the requirements change.
