While developing any application we need to separate the application into different projects. In many cases we need to use the functionality from one project into the other. This article explains available options to achieve this. For this I have created a solution having two projects in Visual Studio :. ArthimaticClassLibrary project has an add method.

The code of the same is shown below. So here Add method takes two integers and returns the sum. There are two options to do it:. Now click on the browse button in the dialog and locate the ArthimaticClassLibrary. In the dialog, expand the Solution option in left pane, click on projects and select the ArthimaticClassLibrary project and click on Ok as shown in the below snap. Now the question is when to use the File reference or dll reference option and Project-to-Project Reference?

If the project or source code is already there in the solution like in our casewe should always go with Project-to-Project Reference approach. Following is an advantage of this approach. Project dependency between the projects will be automatically created by Visual Studio.

So due to these automatically created build dependencies where SampleMvcApplication depends on ArthimaticClassLibrary the dependent project ArthimaticClassLibrary will be built if it has changed since the last time the referencing project SampleMvcApplication was built. A file reference does not create a build dependency, so it is possible to build the referencing project without building the dependent project, and the reference can become obsolete.

That is, the project can reference a previously built version of the project. So when should we use dll reference option? We need to use File reference or dll reference when the corresponding project or source code is not available in the solution. For example, for referring the third part libraries we can use this approach.

I've seen some stuff about "Solution Folders", but these don't seem to be the same thing? This post is old, but these days you can easily reuse dependencies in other solutions by building nuget packages for all of them.

VS has nuget package building built in but is currently a Release Candidate. In Visual Studio you can use the Nuget. Packaging nuget package to allow your project to build as a Nuget Package. Then you can just publish new versions of your packages to a local network share and configure it as a Repository in Visual Studio. In the CoreFramework solution you would build a nuget package for the Utility Project that compiles to the utility dll and include the dll and it's pdb file in the package.

Utilities" and it will install the latest version of XYZ. If you make a change to XYZ. Utilities on XYZEcosystem and it will pick up the new version. Actually the method described adds all projects from another solution to the current solution, not quite what we want, but at least this saves time adding all of the projects manually one by one.

A solution is a collection of assemblies that build to create some kind of executable or dll. Having one solution depend on another does not make sense. If your solution depends on other assemblies, then reference them.

Simply add all the projects that you depend on the projects in the 'other' solution to the solution. How are we doing? Please help us improve Stack Overflow. Take our short survey. Learn more.

A reference is essentially an entry in a project file that contains the information that Visual Studio needs to locate the component or the service. For more information, see How to: Add or remove references. If you choose to retarget Windows 8. If you determine that the Extension SDK being referenced by your app is not supported, then you need to perform the following steps:.

Look at the name of the project that is causing the error. The platform your project is targeting is noted in parentheses next to the project name. For example, MyProjectName Windows 8. Go to the site of the vendor who owns the unsupported Extension SDK, and install the version of the Extension SDK with dependencies that are compatible with the version of the platform your project is targeting.

Look at the right pane in the Reference Manager. If it has dependencies, they will be listed there. If the Extension SDK you installed in the previous step has dependencies on other Extension SDKs, go to the sites of the vendors who own the dependencies, and install the versions of these dependencies that are compatible with the version of the platform your project is targeting.

Right-click on the References or Dependencies node in the project that caused the error and choose Add Reference. Click OK. When you make a reference to an assembly in your project, Visual Studio searches for the assembly in the following locations:. The current project directory. You can find these assemblies by using the Browse tab.

Other project directories in the same solution. You can find these assemblies on the Projects tab. If the project contains a reference to an object that is not in one of these locations, you must copy the reference to the output path of the project when you build the project. The CopyLocal property indicates whether this copy has to be made. If the value is Truethe reference is copied to the project directory when you build the project.

If the value is Falsethe reference is not copied. If you deploy an application that contains a reference to a custom component that is registered in the GAC, the component will not be deployed with the application, regardless of the CopyLocal setting. In earlier versions of Visual Studio, you could set the CopyLocal property on a reference to ensure that the assembly was deployed.

This puts all custom code under scrutiny, reducing the risk of publishing custom code with which you are not familiar. By default, the CopyLocal property is set to False if the assembly or component is in the global assembly cache or is a framework component. Otherwise, the value is set to True. Project-to-project references are always set to True.

You can create applications that reference projects or assemblies that target a different version of the. For example, you could create an application that targets.Often, developers partition their applications into separate Visual Studio solutions in order to make managing the complexity of the overall application easier.

Sometimes, the reverse is true. That is, you may want to combine several existing solutions into one master solution.

The reason for doing this may be to make it easier to navigate between the different files in different solutions or perhaps make the build process for the overall application more manageable.

C# 18: Understanding Namespaces and Adding References to Assembly in Visual Studio

One of the little known facts of Visual Studio is that you can add an existing solution to another solution, without impacting the existing solution. Let's assume for this exercise that you want to add the Engine solution to the Robot solution. The first step is to create a "Solution Folder" in the the Robot solution. Give the Solution Folder the same name as the the solution that you're adding, in this case "Engine".

The reason for crating a Solution Folder is that it acts as a container for all of the projects in the Engine solution. Otherwise, the projects in the Engine solution would be mixed with projects from the Robot solution. The nice thing about this approach is that not only are all the projects now in one solution but at any time, you can open the separate solutions without impacting the "master" solution and vice versa.

Below is a screenshot of a real world example after eight solutions have been combined into one. The "master" solution contains eight other solutions.

You can see that "DinnerNow — Main" contains 31 project, even though these projects are part of other solutions. Habib Heydarian. June 26, at am.You can use the Reference Manager dialog box to add and manage references to components that you, Microsoft, or another company developed.

If you are developing a. NET application, your project automatically references mscorlib. References to COM components or custom components have to be added manually.

The Reference Manager dialog box shows different categories on the left side, depending on the project type:. Assemblieswith Framework and Extensions subgroups. Windowswith Core and Extensions subgroups. The Assemblies tab lists all. NET assemblies that are available for referencing. The Assemblies tab doesn't list any assemblies from the global assembly cache GAC because assemblies in the GAC are part of the run-time environment.

If you deploy or copy an application that contains a reference to an assembly that's registered in the GAC, the assembly won't be deployed or copied with the application, regardless of the Copy Local setting. For more information, see Manage references in a project.

Setting this property to True can cause build issues because of certain EnvDTE properties that can't be embedded. All desktop projects contain an implicit reference to mscorlib. Visual Basic projects contain an implicit reference to Microsoft. All projects contain an implicit reference to System. Coreeven if it's removed from the list of references.

If a project type doesn't support assemblies, the tab won't appear in the Reference Manager dialog box. For projects that don't target. The user must add any references that the application requires. Universal Windows projects contain references to all of the assemblies in the targeted framework by default. In managed projects, a read-only node under the References folder in Solution Explorer indicates the reference to the entire framework.

Accordingly, the Framework tab doesn't enumerate any of the assemblies from the framework and instead displays the following message: "All of the Framework assemblies are already referenced. Please use the Object Browser to explore the references in the Framework". Extensions lists all assemblies that external vendors of components and controls have developed to extend the targeted framework. Depending on the purpose of the user application, it might need these assemblies.

Extensions is populated by enumerating the assemblies that are registered in the following locations:. For example, if a project targets. Some components in the list may not be shown, depending on the framework version of your project. This can occur under the following conditions:. A component that uses a recent framework version is incompatible with a project that targets an earlier version.

For information about how to change the target framework version for a project, see Framework targeting overview. A component that uses. NET Framework 4 is incompatible with a project that targets the. NET Framework 4. You should avoid adding file references to outputs of another project in the same solution, because doing this may cause compilation errors. Instead, use the Projects tab of the Add Reference dialog box to create project-to-project references.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I have an external configuration file, for a third party tool, which I would like to be able to edit as part of editing other project components in VS The project I'm working on is an MVC-3 project, and the file is located outside of the folder structure for the project it's in the equivalent of. How do I add a reference to this file to VS? Currently, all my attempts have resulted in VS creating a copy of the file inside of its directory structure, which is not ideal.

Sure, I could go to some strange lengths, like adding a script to the build process to put the config file in the right place, but I'd rather just be able to edit it where it sits. How are we doing? Please help us improve Stack Overflow.
