I have a solution that consume a nuget that have all DTO classes(DataObjects).
When developing I want to create new DTO's. To avoid to have to add the DTO to the external project DataObjects and recompile and republish the nuget just to have access to the new DTO in my project, I have created a project(DevObjects) that have the same namespace.
I just pop a new DTO class into DevObjects and continue developing.
When I'm done with that particular job I move the DTO to the DataObjects recompile and publish the nuget.
This works fine except that when I publish the the library that I was working on as a nuget, it list DevObjects as a dependency even thou it is not referenced in code.
How can I exclude DevObjects from the library nuget?
The only workaround I can think of is to publish a dummy nuget of DevObjects just to make nuget happy, but it does not feel like a palatable solution.
When I'm done with that particular job I move the DTO to the
DataObjects recompile and publish the nuget.
I think you have added project reference like DevObjects which contains the file DTO into DataObjects project Also, l think the projects are based on Net Standard. When you package DataObjects, it will generate the dependency to DevObjects. This is the normal behavior.
In a way, when you package the project as nuget, the generation of dependencies really means adding project references.
How can I exclude DevObjects from the library nuget?
You can just remove DevObjects by some changes into DataObjects.csproj
> change the include into remove
<ProjectReference Remove="..\xxxx\DevObjects.csproj" />
Besides, you can exclude the reference project by UI Control.(Right-click on DataObjects-->Dependencies-->Add Reference-->Projects-->uncheck DevObjects)
Conclusion
When you package a project, the Project Reference adds a dependency to your nuget package. So if you do not want to have this dependency, you can just add the DTO class as an Existing Item into DataObjects project. Hope it could help you.

I have a solution with an application project (ASP.NET Core) and multiple library projects. I want to separate some of the library projects into a separate solution and turn them into NuGet packages.
With the libraries in the same solution I could of course simply edit something in a library, run the application and see how it works (and debug, if necessary).
However, when I turn the libraries into a NuGet package, the application references the packages from our private NuGet feed instead of the project file.
My question is: is it possible to locally "override" the package reference and use the local source code instead? That way I could still edit the libraries and see the effects in the application. This is a lot easier than having to publish a new package for every small change (especially when trying to fix an issue or implementing a new feature).
DNT (Dot Net Tools) does this. You can specify which packages to switch and where they are.
See the 'switch-to-packages' and 'switch-to-projects' command line switches.
Its a bit fiddley as (when I last tried) you had to create a config file that holds the mapping, and it seems to be easy to break the switching. But its something.
https://github.com/RicoSuter/DNT
I've not tried it, but maybe you can use it to switch to packages on a commit for the build server to work correctly? (Or to ensure the references are correct in source control?)
If you want to use nuget in your project and debug, even modify the source files of the nuget packages, this is not a good choice because you should build the nuget project(generate the new changed dll) and repack it as a nuget package, then reinstall, to enable the changes. It is too complex.
Once you install the nuget, no matter how many changes you make, it’s useless. The nuget installed at this time is the version you made before any changes. No matter how you change it, it is the previous version. The version stays at that timestamp, unless you repackage the project. Generate nupkg and update the nuget version.
So nuget is not a good choice for your situation, you should use ProjectReference.
Directly use the ProjectReference to reference two source projects, build at the same time, and get the changed parts at the same time.
ProjectReference could cross two different solutions.
Add this on the main project:
<ItemGroup>
<!--add any nuget project'csproj file like this to debug its source code-->
<ProjectReference Include="..\xxx\xxx.csproj">
</ProjectReference>
</ItemGroup>
If the proejct is out of the solution, you could directly use the full path of the nuget project's csproj to connect it.
I'm not sure what you mean by "override" but you can always add the library project to your ASP.NET Core solution and reference it like normal project references. A project referenced within a solution doesn't have to be physically placed in the same folder as the solution itself.
This, however, does require that any developer on the project has both GIT repositories cloned locally (given your two solutions are located in separate GIT repos) in order to be able to build the ASP.NET Core solution. But I don't really see that as a downside.
I'm a newcomer to .NET world, and at this point I'm super confused about the packages, references and how to reference them in my c# project.
I have 3 project in my solution:
DataAccess - which contains the logic for accessing data, the mapping between DTOs and entities, etc.,
DataAccessTest - contains unit tests for DataAccess project,
Service - wraps the DataAccess project into a Windows service.
Now, DataAccess project references AutoMapper (among others) to help with data transformation. It's included in <PackageReference /> element in the csproj file. It seems to be working fine when I'm doing dotnet restore, however dotnet build fails when trying to resolve the namespaces! The same goes for JetBrains Rider - it doesn't find the namespaces until I explicitly reference them in <Reference>!
Not sure if related, but the same goes for the dependent projects. For example, DataAccessTest references the DataAccess project - so that the test will run. However, it still requires adding the transitive dependencies (for example AutoMapper), on top of the project reference.
Is this the intended behavior? Do you need to keep both <PackageReference> and <Reference> for project to compile correctly?
In C# you Have to take care about referencing to other projects. if one project has been referenced to other project, the other project couldn't use or reference to first project. if you did, it will gives you compilation Error.
You need to install Nuget packages for each project that references methods in that package. So, if only your DataAccess project requires AutoMapper, it should be sufficient to add the Nuget package to that project. The solution is not much more than a wrapper around a bunch of projects. You should be able to publish a project separately. The project will take care of its own dependencies. It is hard to find out what goes wqrong. It may be helpful if you create a small testproject, e.g. create an empty console project and a DataAccess Library. Then you add a Nuget package to your DataAccess library and copile all stuff. In this way you can try to find out what is goning wrong. Make sure to install the Nuget Packages for the correct project (I got this wrong several times before I discovered how it really worked).
This is the basics of the problem I am having (of course it is oversimplified for the sake of the question):
I have 2 projects in a solution stored in mono-repository:
Project1 - outputs a library
Project2 - outputs an executable
When Project2 references Project1.
I would like to move to multi-repository where Project1 will be stored in different Repository from Project2.
Project1 will output a nuget package and Project2 will reference it instead the project itself.
The issue I am facing: in current situation (mono-repository) when during development I introduce a feature in
Project2 that also requires a change in Project1 it is not a problem. If there are problems I can discover it
during development time.
In a new way (multi-repository) I first need to make a change to Project1, create nuget and push it to nuget
store, then update reference in Project2. If I would have problems in Project1, I must go back to Project1,
fix the issue and push it again, update reference in Project2 and so on. Also, losing the benefit of debugging
both projects.
Is there a solution to this approach? To focus my question: if I have source codes of both projects on my dev machine,
is it possible somehow to instruct Visual Studio to use source code instead of referenced Nuget for debugging?
Hope I explained it right and clear as possible...
If you have two different projects and both of them are in different repositories, you could add the library as a submodule of the first project. I'm assuming you're using git. You could do this simply by:
git submodule add <link for the other repo>
In visual studio you just add the project to the same solution and then reference library from the executable. I'm not sure if that would do the trick for you, but I hope that works.
We have the exact same problem in our company.
This is 2 part problem.
First part is to have both repositories near each other... There are more options, we were deciding between these 2:
git submodule
meta repository (it is a compromise between mono-repository and multi-repository) you have 2 repositories you want to connect, so you create 3rd repository as a meta-repository via https://github.com/mateodelnorte/meta
Second part is how to connect those 2 repositories so that they are debuggable, but still apart each other... We though of these 3 ways:
new .sln in meta repository that will reference both projects (this didn't cut it, because we already been in a position when we had multiple .sln files and maintaining them is not that easy, because when you add some project into one, you have to add it to the other solutions and this goes sideways really quick)
using Reference and PackageReference with Condition - locally for debugging when .dll is build in ProjA then the ProjB would use "Reference", if not the ProjB would use PackageReference => this was our main solution to our problem until we did it like that... (Because we have more than 2 projects ProjA -> ProjB -> ProjC.. The problem here was when it was built locally, referenced via Reference DLL, then ProjA was not visible from ProjC, but when built via CI and referenced via PackageReference, then ProjA was visible from ProjC)
using only Nugets - Every build of ProjA it will create nuget locally (pre-release) and in ProjB, we would reference that via wild-cards. This works, until you make a second change into ProjA, because ProjB will cache that nuget in C:/Users//.nuget/packages :( so when building ProjA and packing the nuget we clear the newly built nuget from this packages folder. You have to restore ProjB every time you make change into ProjA, but this is where we landed as a final solution for now.
So the final solution for us is:
meta-repository for like 5 other repositories
for debugging we use locally built nugets with constant version of "major.minor.patch.65534-local"
for CI we use the same nuget packaging but we override the local version with
feature branches "major.minor.patch.build_number-branch_name" (having -something after the version makes that nuget pre-release)
master/main branch "major.minor.path.build_number"
I need to create csproj file that will be usable as project reference in VS2013 and will output prebuilt binary as it's "Build" result.
We use referenced projects for build, however company policy doesn't allow access to some of that projects for everyone. As a result projects need to be updated manually to make them build. This is really a major inconvenience when switching branches and when making edits to project files, so I want to create dummy project that will be bound to pre-built binaries as their "output" and will be placed instead of real projects.
EDIT: Moving that assembly to Nuget package is not an option for now since Nuget has some issues with dev flow (when you need to debug/test/develop package). I saw some VS extension that implements switching between Nuget package and local project which might solve this issue, but I'm not sure if it will be accepted and want to explore other options.
To be clear - the thing I want to avoid is editing project in any way, so that project can be built cleanly after pulling it from Git, and I don't have to clean it every time before commit.
I haven't properly tested it, but the solution seems really simple (if I understand the question properly).
Just add this to the existing .csproj, overriding the Build target to just give the path to the pre-built assembly.
<Target
Name="Build"
Returns="$(TargetPath)" />
This assumes the TargetPath property already defined, and it should automatically be if you're modifying the original .csproj. Otherwise just define it yourself in a <PropertyGroup> before the Build task.
Note that having TargetPath defined is important for the ProjectReferences in your own project to resolve.
How about having those restricted (binary only) projects reside in an internal Nuget package feed, so that Nuget can install the packages as needed, on build?
I am attempting to publish and consume versioned NuGet packages of class libraries while avoiding headaches for local development. Here is a sample Visual Studio solution layout:
| Libraries
| LibraryA
| LibraryB
| LibraryC
| Applications
| ApplicationD
| ApplicationE
This is a single solution containing both shared class libraries and multiple applications. Currently references to the class libraries by the applications are local in-solution references.
What I would like to do is to publish the libraries (A,B,C) as versioned NuGet packages which are then referenced by the applications as needed (D,E). This allows a change to a shared library to be independent from an update to an application which is deployed. Without this, changing one library could cause the binaries to change in a dozen or more applications, all of which would technically need to be tested. This is undesirable, and versioning with NuGet fixes this.
However, let us say that I want to update the content of LibraryA and ApplicationD at the same time. In order to do this after we have switched to NuGet, I will have to make changes to LibraryA, commit them, wait for the package to be created, tell ApplicationD to update its reference to LibraryA, and then test or develop in ApplicationD. This is far more complicated than simply working with both at the same time using local in-solution references.
What is a better way to get both the robustness of versioned NuGet packages for my shared class libraries while also keeping development simple even if it spans over multiple projects and applications? The only other solutions I have found all involve too much overhead or headache, such as having to constantly change the references for ApplicationD between the NuGet package and the local project.
EDIT: To clarify the premise, this question assumes the following:
The architecture (solution and project organization) cannot be significantly reorganized
Shared libraries are going to change at a non-trivial frequency
Changing a shared library cannot force any application to be updated
Applications can reference different versions of shared libraries
Although it takes some work, it is possible to hand-edit .csproj files in order to set up conditional referencing by adding a Condition attribute to the appropriate references.
EDIT I've moved these conditions into ItemGroups, as it seems this is how my mentioned production code is working, and there has been mention of this being a possible issue in VS 2013.
<ItemGroup Condition="'$(Configuration)' == 'Debug Local'">
<!-- Library A reference as generated by VS for an in-solution reference, children unmodified -->
<ProjectReference>...
</ItemGroup>
<ItemGroup Condition="'$(Configuration)' == 'Debug NuGet'">
<!-- Library A reference as generated by NuGet, child nodes unmodified -->
<Reference Include="LibraryA">...
</ItemGroup>
This would allow you to have, on the Projects D & E, configurations of "Debug NuGet" vs. "Debug Local" which reference the libraries differently. If you then have multiple solution files which have their configurations mapped to the appropriate configurations on the projects within, the end user would never see more than "Debug" and "Release" for most operation, since those are the solution configs, and would only need to open the full solution for editing the A, B, & C projects.
Now, as for getting the A, B, & C projects out of the way, you could set them up under a folder marked as a subrepo (assuming you're using an SCM that supports this, such as Git). Most users would never need to pull the subrepo since they're not accessing the ABC projects, and are instead grabbing from NuGet.
Maintenance wise, I can guarantee that VS will not edit the conditional references, and will respect them during compilation -I have gone through both VS 2010 and 2013 (EDIT: Professional version, though I have delved into doing the same with express) with the same conditional reference projects at work. Keep in mind than in VS, references can be made version-agnostic, making NuGet the only place from which version need be maintained, and that can be done like any other NuGet package. While I'm hopeful, I have NOT tested whether NuGet will fight with the conditional references.
EDIT It may also be prudent to note that conditional references can cause warnings about missing DLLs, but does not actually hinder compilation or run.
EDIT For those still reading this, I'm now (7/2019) hearing that the IDE isn't as friendly to these changes anymore, and either it or the Package Manager may override them. Proceed with caution, and always read your commits!
Update for .NET Core (2.x ++)
.NET Core 2.x actually has this functionality built in!
If you have a project reference to project A in project B, and project A is a .NET Standard or Core project with proper package information (Properties -> Package with Package id set to your NuGet package ID), then you can have a regular project reference in project B's .csproj file:
<ItemGroup>
<ProjectReference Include="..\..\A\ProjectA.csproj" />
</ItemGroup>
When you pack (dotnet pack) project B, because of the Package id in project A, the generated .nuspec file will be set up with a NuGet dependency to that Package ID, together with other NuGet references you might have, instead of just including the built DLL file.
<dependencies>
<group targetFramework=".NETStandard2.0">
<dependency id="Project.A" version="1.2.3" exclude="Build,Analyzers" />
<dependency id="Newtonsoft.Json" version="12.0.2" exclude="Build,Analyzers" />
</group>
</dependencies>
I know this is a 2-years old post, but just found it while facing the same situation. Also found this for VS2015, I'm in the process of testing it. I'll come back and adjust my answer accordingly.

I also faced a similar problem. One approach that worked was using local repository (which is basically just a folder in local) and adding post-build script in the libraries. For example: let's say you need to update your implementation for LibraryA, then include following 3 steps in your post-build event for LibraryA:
Check if local repository has that version of package; if yes then delete it
rd /s /q %userprofile%\.nuget\packages\LibraryA\#(VersionNumber) -Recurse -ErrorAction Ignore
Create a nuget package
nuget pack LibraryA.csproj
Push it to local repository
nuget push LibraryA#(VersionNumber) -Source %userprofile%\.nuget\packages
These steps will make sure that the package is always updated for that version after each build (we had to do this since nuget packages are immutable)
Now in ApplicationD, you can point to local repository (%userprofile%.nuget\packages) to get LibraryA; such that after each build of LibraryA, you will receive an updated version of it in ApplicationD
PS: Inorder to get version number of you library you can use this : Determine assembly version during a post-build event
Unfortunately, there really isn't a way to have the best of both worlds. Internally in my company, we've mitigated it somewhat with a fast build/deploy process, which counteracts most of the burdens with always referencing a NuGet package. Basically, all of our applications use a different version of the same library hosted in a local NuGet repository. Since we use our own software to build, deploy, and host the packages, it makes it pretty quick to update the library, then update its NuGet package in another solution. Essentially, the fastest workflow we've found is this:
Make changes to library
Automatically build and deploy version of library incremented by 1 to internal NuGet feed
Update NuGet package in consumer application
The whole process from check-in to updating the consuming project takes around 3 minutes. The NuGet repository also has a symbol/source server which helps tremendously with debugging.
In the properties of ApplicationD, go to the "Reference Paths" tab and add the path of the output folder of LibraryA. Then, if you change and build LibraryA, the next build of ApplicationD will use the modified LibraryA.
When you are finished, don't forget to remove the "Reference Paths" and update the referenced NuGet package version.
My not-so-clean yet fastest solution so far is:
Assuming the following two separate solutions:
VS Solution 1: contains libraries published as nuget packages:
Solution1
|_ my.first.library
|_ my.second.library
VS Solution 2: contains applications, which consume one or more of the above libraries as PackageReferences:
Solution2
|_ my.first.application
| |_ depends on nuget my.first.library (let us say v1.0.1)
|
|_ my.second.application
In case, I'm making changes to my.first.library
I proceed as follows:
Make code changes to my.first.library and rebuild
Navigate to the build output directory of my.first.library (e.g. <Solution1 directory>/my.first.library/bin/debug/netstandard2.0) and copy the .dll and .pdb files
Navigate to the my.first.library's local directory of the currently being used nuget feed (for example at: C:\Users\user.name\.nuget\packages\my.first.library\1.0.1lib\netstandard2.0) and replace the .dll and .pdb files there with the ones generated in step 1 (possibly making backup).
Changes get reflected in my.first.application. Continue working and repeat steps 1-4, when needed
Advantages:
being completely local. No secondary nuget feeds needed.
zero changes to .csproj/.sln files
Caution:
While this solution offers you flexibility, make sure you clear your nuget cache before acting on them, for example by publishing to a nuget server. Thanks #Benrobot
