Project won't build when I change configuration in Visual Studio - asp.net-mvc

I refactored my MVC/Entity Framework projects by separating namespaces into separate projects. So I now have this structure:
MySolution.Data
MySolution.Data.Contracts
MySolution.Model
MySolution.Website
Everything builds and runs in my development environment. However I hit problems when I tried to deploy to my "Staging" server.
The problem I have is that it would not build when I changed the solution configuration to "Staging". In the configuration manager all the projects also have "Staging" configurations. I assume these were created when the new projects were added.
The first thing I tried was to create a new solution configuration with everything copied from Debug named "Solution 2". No luck, still fails.
Then I figured that I only need a different configuration for the Website project - where I transform the configuration file. So I changed the solution configuration, telling it to build and deploy the "Debug" configuration of Hub.Model - which from the first error message looked like the problem project. Sure enough it now builds.
The first error message (of 263) is:
The type or namespace name 'Schema' does not exist in the namespace 'System.ComponentModel.DataAnnotations' (are you missing an assembly reference?) MySolution.Model
So it looks like a problem with references to Entity Framework dlls
While I do have a workaround for now, I am concerned that this unexplained error will come back and bite me at some point in the future - probably just when I am about to deploy an urgent fix.
So why would one of my projects fail to build when I change project configuration?

You need to make sure you are installing proper nuget packages and referencing all assemblies.
The solution of the error you have shown is as below: (Reference)
You have to reference the assembly in which this namespace is defined
(it is not referenced by default in the visual studio templates). Open
your reference manager and add a reference to the
System.ComponentModel.DataAnnotations assembly (Solution explorer ->
Add reference -> Select .Net tab -> select
System.ComponentModel.DataAnnotations from the list). Then select that reference and under properties set "copy local" to true and once you publish it will be in your bin folder and wont impact at all on any server be it x32 or x64.
Happy coding :)

Adding references search folder for MSBuild from Visual Studio Build definition UI

I am working on configuring a XAML build definition for a .net solution (of another company) stored in TFS2015.
The solution uses Dll references from a software X, installed on the developers computers, but not present in the Build server. (FTS and Build servers are shared among many clients).
I have option to add the required Dlls in a folder along with the source code, but I do not have option to modify the .csproj files.
In the Build definition, I tried to add the following in the MSBuild arguments field :
/p:AdditionalLibPaths=$/[long tfs path here]/CommonDlls
/p:AdditionalLibPaths=$(SourceDir)/CommonDlls
but it is not working.
Ideally, I would like to specify a relative folder from the root of the source code.
(a static path might work but only for one build server and agent, which is not the objective of shared build).
Any ideas on how I can define this parameter ?
There is also option to add a prebuild script path. I can store a script file along with source code. Any pointers for how to write such script file ?
You do not really need a script.
There are two things to make this work.
The first step is making sure that the DLLs are downloaded to the Agent working folder, the simplest way is have the $/[long tfs path here]/CommonDlls mapped in the Build Workspace; this is specified in the Source Settings tab of the Build Definition. Be careful to use the $(SourceDir) token in the mapping (see here).
The second point is to use a proper reference to the downloaded folder: use the TF_BUILD_SOURCESDIRECTORY variable (see here for full list).
So, if you added a mapping like
$/[long tfs path here]/CommonDlls -> $(SourceDir)\CommonDlls
use $(TF_BUILD_SOURCESDIRECTORY)\CommonDlls.
It took me almost 20 trials to get the right one, it all started with how long it took that warning to consider all other directories, I could've ignored it but here's the warning first
C:\Program Files (x86)\MSBuild\14.0\bin\Microsoft.Common.CurrentVersion.targets(1820,5): Warning MSB3245: Could not resolve this reference. Could not locate the assembly "nameOfDllFile". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.
and this is the argument that got it working
/p:ReferencePath="$(build.sourcesdirectory)\Binaries"
where Binaries is the equivalent to CommonDlls from the question, and it is all because of the vague documentation and differences between versions of MSBuild, mine is 14.0 (VS2015).

TFS custom build process activity assemblies per branch

What do I do if I want one TFS 2012 build controller to have access to two versions of the same custom build process assembly (one for each of my branches)?
I have one build process template per branch, and one build definition per branch. Each branch has it's own custom build process assembly, but they all have the same assembly name and namespace (e.g. Company.Build.Activities.dll). (I realize I could make all of this go away by having different names for each branch's assembly, e.g. Company.Build.Activities.Dev.dll and Company.Build.Activities.Com.dll)
My build controller points to one location for "Version control path to custom assemblies" ($/Build/ForTFS). I tried putting the two assemblies under different subfolders, but the build process causes an error:
TF215097: An error occurred while initializing a build for build definition \Company\Dev_BuildDef:
Exception Message: Cannot set unknown member 'Company.Build.Activities.LastActivity.CustomFolderPath'. (type XamlObjectWriterException)
It seems that it's using the wrong copy of the assembly (CustomFolderPath is only defined in one assembly, not the other).
I think I could resolve this if I could specify the path or required assembly version in the template xaml, but I am not sure I can do that. I have read posts that suggest that you can add a reference to the specific assembly version in the Visual Studio project you are using to edit the template. But that didn't seem to work for me, and how would the build process definition know about that project's references... it only points to the template file itself, not the project.
Any suggestions? Am I approaching this wrong?
You cant have different assemblies loaded between different branches. You would need to run different controllers and use separate folders.

TeamCity Build Web Solution with Multiple Projects ASP.NET MVC

I have what I believe is a really common scenario with an ASP.NET MVC 3 solution. It has a WEB project and a DAL class library. I have the all my data access in the class library, which is required to be built before the web project.
When I rebuild my solution in standard Visual Studio I have no issues. But lets say I make a data change (for example to the database) and check in the DBML (LINQ to SQL) file and the corresponding reference files from the WEB Project.
What I'm seeing is TeamCity not cleaning/rebuilding the class library DLL at all. Below is my solution configuration. How can I force TeamCity to rebuild each project as it doesn't seem to be doing such. I have to actually check in the bin/debug DLL locally in order for TeamCity to successfully build. I feel that should not be the case. Do I need to setup a build step for each project...?
How can I force TeamCity to rebuild each project as it doesn't seem to be doing such.
I think the surest way to do this is to enforce a clean checkout of the source tree prior to each build. (see also: nuke it from orbit.)
You can have TeamCity do this for you by enabling the Clean all files before build option on Version Control Settings -> Checkout Settings. This option deletes the entire checkout directory and does a full, clean checkout of all the sources prior to the build. The TeamCity 'Clean Checkout' documentation has more info.
Sounds like your build configuration (in Visual Studio) is messed up.
First off, make sure your DAL reference is a project reference, not a file reference.
The easiest way to correct this is to remove the reference and re-add it. While adding, ensure you are looking at the projects tab. This should reset the project dependencies.
To ensure that the MVC project depends on the DAL project, right-click on the MVC project and select Project Dependencies... from the context menu. The DAL project should be checked.

Deploying Custom Policy on TFS2010 using VSIX and PKGDEF

I'm having a hell of a time trying to get a custom policy to install on TFS2010 using VSIX.
I have the policy up and running and working fine on my development PC, I have written a value to the registry manually, and the policy is enforced.
The trouble is setting up a VSIX project and deployment to our other development machines.
I followed the instructions in:
http://blogs.msdn.com/b/jimlamb/archive/2010/03/31/how-to-implement-package-and-deploy-custom-check-in-policy-for-tfs-2010.aspx
The preferred method appears to be to use the new VSIX project type in VS 2010, I add a VSIX project to my solution, but the instructions in the blog entry are very vague about what to do next. My understanding is that the PKGDEF file means you do not have write a value to the registry when deploying, and the content of the PKGDEF file is rolled into the config when you start Visual Studio. That's fine, but how do you build up the VSIX package?
I tried adding the custom policy project to the VSIX project as a VS Package type, but when I build I get the error: The target "PkgdefProjectOutputGroup" does not exist in the project.
I have tried adding just the dll, the pkgdef file as a custom content type, etc, but nothing works.
I have changed the PKGDEF file in the blog to match my own project.
When I install the VSIX package on a development machine, I can see the add-in in the Extensions Manager in Visual Studio, but when I check the custom policies in TFS, I get the "is not registered" error.
I really need a step-by-step to setting up a VSIX project to deploy a custom policy, can anyone help?
The blog post definitely has a missing step. I think what the author intended was that you add the pkgdef file to the VSIX project (via the vsixmanifest editor) as Content of type VS Package. Then, add a project reference to the checkin policy project from your VSIX project (which will cause the checkin policy DLL to be added to your VSIX).
As a side note....when you pick "VS Package" as the content type and then point to a project...it needs to be a proper VS Package project (not just a vanilla C#/VB class library).
The problem is the assembly name "NArrange.CheckinPolicy.dll" does not match the name in the Policies.pkgdef. To correct this make sure that your Policies.pkgdef looks like this:
[$RootKey$\TeamFoundation\SourceControl\Checkin Policies]
"TeamFoundation.Samples.CheckinPolicies"="$PackageFolder$\NArrange.CheckinPolicy.dll"
Additionally I would avoid further confusion by changing the "Product Name" in source.extension.vsixmanifest to NArrange.CheckinPolicy. This way the assembly will match the product name in VS Extensions.

Why are some solutions not building completely with TFS?

I'm noticing some solutions in Team Foundation Server 2008 won't build completely. As in, some number of the projects in the solution succeed but then one fails. The particular failing project says I’m missing an assembly reference. But I'm not - the project has the reference. It builds fine on my PC. I'm looking at the .csproj file that the build agent pulled down and it has the reference, too (it's line-for-line identical to the project I'm building).
The reference in question is to another project in the solution. At first I thought it wasn't building projects in the right order but the build log is telling me that it did (i.e., the project which the reference is in reference to built successfully). So my guess is that somehow on this project (and I’d say about 10-20% of the projects I’m having it build are failing) it’s looking at the wrong folder for assemblies, but I have no idea.
Has anyone ever seen this before?
I did have one Solution which was building things in the wrong order and some Googling seemed to indicate that this was an occasional side-effect of converting a VS2003 SLN file to a VS2008 SLN file (and it was happening in Visual Studio as well), so in that case I made a new SLN from scratch, checked that in "on top" of the problematic one, and it worked fine. But I tried that in the problem above and it didn’t make a difference.
I've seen it on multicore machines where the project dependencies haven't been setup correctly, meaning that tfs starts a project compiling before it's dependencies are finished compiling.
At first I thought it wasn't building projects in the right order but the build log is telling me that it did (i.e., the project which the reference is in reference to built successfully).
Define "built successfully." In particular, make sure the CoreCompile target was invoked and ran to completion. I've seen cases where a different target on the referenced project was built, but that target was insufficient to generate the output the dependent project needed. For example, a web project that includes a Silverlight control will call the GetXapOutputFile target on the Silverlight project -- which is fine & dandy, but it's no replacement for CoreCompile.
If this clue isn't enough to resolve your issue, you should probably post a link to the log and/or the msbuild makefiles.
