MSBuild and .CsProjects - msbuild

I am using MSbuild for CI tool and have many C# projects located in different directories. There many dependents projects as well. Some developers use Add Project option to add project and some directly connect to .dll file and i have no control over it. some cases all projects added to a solution So if i compile that solution then it takes care of all dependencies. But i do not this in my auto build. I want to compile all .csproj and output .dlls to a particular folder and then all projects including web should point to this folder for reference.
Want to know if this a ideal process?

In my Project we do the same and it works. Sometimes we have project references and sometimes we have direct dlls references in a folder called "Solution DLLs".
How we do it:
The reason is that we have many projects (120 or more) and we have split them in several solutions. One of the solutions is for framework and commmon dlls. These Dlls are copied in postbuild scripts to a "Solutions Dlls" folder and checked in in TFS. Later our build scripts copy these solutions dlls...
How it works:
It works "fine" and is acceptable. But many problems came (and sometimes still come) with postbuild scripts not working fine. We are aiming to reduce the number of csprojs to 50-60 and use again one single solution.

MSBuild task does not build solution file

I have a project file that should build another solution. I tried using the MSBuild task for this, like this:
<MSBuild Projects="MySolution.sln" Properties="Configuration=$(Configuration)"/>
I tried a lot of variants, like supplying hardcoded configuration, target Rebuild and so on. Building reports an error when I pass a wrong solution name, non-existing configuration or target and so on, so it definitely loads the solution and the project files. It exits relatively fast though and produces no output. According to documentation and examples, this should work though. I also tried passing an ItemGroup for the project, including project-specific properties as suggested by examples or in MSBuild - How to build a .NET solution file (in an XML task script) from pre-written command line commands , but that does not work either. It runs without error but no output.
When passing a list of project files instead (or a single project file), it builds correctly, but the problem is that dependencies between the projects are not properly resolved. At the end, I have to supply all project files in the solution and add them to the list, which is what I want to avoid.
So, why does solution building not work, even though it should? What is wrong here?
Is this a .net project? If so you probably need to pass in a platform as well as a configuration.
<MSBuild
Projects="MySolution.sln"
Targets="build"
Properties="Configuration=$(Configuration);Platform=$(Platform)" />
If the project just contains web sites and libraries then the platform should be Any CPU if your solution just contains executables then x86 or x64 or if it's a mixture of different types of platform then you can use mixed platforms
To check what are available open the solution in Visual Studio, right click on the solution in solution explorer and select "Configuration Manager" you'll then have a drop down for "Active Solution Platforms"

Using VB.NET, how can I bring an existing project in an existing solution into a new solution so that it resides completely within the new solution?

I am creating an application which will coordinate and organize a lot of standalone functions. For instance, the main application might be called ABC Company Operations, and within it might be Engineering Bills Of Material and Project Management Purchase Orders, among many others. I want to develop each of these tools as a standalone solution, then include them in the main application when I am done with them. For one thing this will allow me to distribute the main application with a fair number of tools complete, then issue an update when each new one is included, and for another thing having these functions in their own projects will cut down on the madness inside the solution explorer.
Searching and reading have shown me how to include existing projects in a solution, but they are included as a reference - the files continue to reside in the standalone solution. This is not good because I wish to make any changes needed in the standalone, then replace the project in the main solution when those changes are done and also because I would prefer not to have all these solutions hanging around in a public place.
I tried just copying and pasting the project directory from the standalone solution into the main solution, but the solution explorer hasn't picked it up and there are somehow two listings of the standalone in the main Visual Studio screen where you select which solution you will work on. This seems like a bad road, so before I continue down it I would like to ask for any advice you folk may have.
Visual Studio allows you to reference the same project in different solutions.
Right click the solution in the solution explorer > Add > Existing Project...
I have done it and it works perfectly.
But very often referencing the DLL of a class library project is just enough. Usually you would reference the bin\Release version. You can even reference an EXE.
I achieve something like what you want by using the Subversion code management system. I keep each project in a directory. These are top-level directories in the Subversion repository.
Each solution is also a top-level entry in the Subversion repository, but does not have any projects in with it. So I have in my repository something like this:-
project directory
project
files directory
files
project directory
project
files directory
files
single-project-solution directory
single-project solution
single-project-solution directory
single-project-solution
multiple-project solution directory
multiple-project solution
I then use svn:externals to include all the needful project directories when either a single project solution or a multiple project solution is checked out, and it ends up in the working copy like this:-
multiple-project solution directory
multiple-project solution
project directory
project
files directory
files
project directory
project
files directory
files
or
single-project-solution directory
single-project-solution
project directory
project
files directory
files

msbuild, multiple projects and dependency resolution

I have solution that consists of 10 projects. Each project has a test assembly (making 20 projects).
Currently, my build script builds all the test assemblies, then runs all the tests, great.
Except that each test assembly references 2 or more of the core assemblies (directly and indirectly), which means there is lots of redundant building going on.
How can I simplify things (without reducing number of assemblies) to speed up the build?
I guess I could build each project directly without resolving the inter-project references and bung it all in a single output dir, but how do i still resolve the other references projects have to 3rd aprty ddls etc.
Other suggestions?
thanks
I am working on a tool to automate the build process it is still on development and it's open source here is the link:

To speed up your build you could try to build in parallel your projects:
http://geekswithblogs.net/deadlydog/archive/2012/03/30/parallel-msbuild-ftwndashbuild-faster-in-parallel.aspx
http://www.hanselman.com/blog/FasterBuildsWithMSBuildUsingParallelBuildsAndMulticoreCPUs.aspx
To force MSBuild to use a single output directory:
<BuildProperties>
Configuration=$(Configuration);
Platform=$(Platform);
OutputPath=$(BuildingPath);
$(BuildProperties);
</BuildProperties>
<MSBuild Projects="$(FullSolutionFilePath)" Properties="$(BuildProperties);" Targets="ReBuild"/>
Can you build the referenced assemblies first, copy them to a "Common" folder, and have the "Common" folder assemblies referenced in the using projects as "Referenced Libraries"?
We do this with our CompanyName.Enterprise libraries and it works fine. They get built once or twice a year and the projects using them build daily.

I would like to have my AssemblyVersion in my deployment package name

I am using MSbuild to create a deployment package (simply copying various files from the projects in my solution to different folders) I would like the root folder to be of the format
DeploymentPackage2.3.4.5ForRelease
How can I get MSbuild to put the Assembly number in the folder name automatically?
EDIT:
The solution has a great deal of projects in it (too many really) they all get their version number from a SharedAssemblyInfo.cs file that is manually updated but in the fullness of time will pick up the svn build number (but that is a job for later)
I am building using an external .bat file that calls a custom written .targets/.proj setup that simply calls msbuild on the .sln of the solution.
The 'create package' step I am trying to create happens after a succesful build and will eventually be run by our CI framework, however I would like to be able to run it locally too.
I have created a "CreatePackage" target that does the copying that I want, however it is currently into a fixed folder. I need the folder name to reflect the AssemblyVersion of one of the final dll's.
If there is a better way then I want to know about it... but I am going to use this I think
MSBuild Task to read version of dll

MSBuild overwriting dependencies

Ok, so I've got a somewhat complicated problem with my build environment that I'm trying to deal with.
I have a solution file that contains multiple C# projects which is built by a NAnt script calling MSBuild - passing MSBuild the name of the solution file and a path to copy the binaries to. This is because I want my automated build environment (CruiseControl.Net) to create a folder named after the revision of each build - this way I can easily go back to previous binaries for any reason.
So idealy I have a folder layout like this
c:\build\nightly\rev1
c:\build\nightly\rev2
c:\build\nightly\rev3
...
c:\build\nightly\rev10
etc.
The problem that's arisen is I recently added the latest version of the Unity IoC container to my project, checking it directly out of MS's online SVN repository. What's happening is I have a Silverlight 3 project that references the Silverlight version of Unity but I also have other projects (namely my Unit testing project) that reference the standard (non-Silverlight) version of Unity.
So what happens is since MSBuild is dumping everything into one single folder the Silverlight version of the Unity assembly is overwriting the non-Silverlight version because they have the exact same assembly file name.
Then when CruistControl runs my unit tests they fail because they don't have the proper dependencies available anymore (they try to load the Silverlight specific Unity assembly which obviously doesn't work).
So what I want to do is:
keep my desired output directory
structure (folder\revision)
I don't want to have to manually edit
every single proj file I have as this
is error prone when adding new
projects to the solution
Idealy I would like MSBuild to put everything into a folder structure similar to this:
nightly\revision1\project1
nightly\revision1\project2
nightly\revision1\project3
...
nightly\revision2\project1
nightly\revision2\project2
nightly\revision2\project3
etc
I can't modify the Unity project to give it a different file name because it comes from another SVN repository I cannot commit changes to. I found a similar question posted here and the suggested solution was to use a "master" MSBuild file that used a custom task to extract all the project file names out of the solution then loop over each one building them. I tried that but it doesn't build them in the order of their dependencies, so it fails for my project.
Help?
Firstly I would always have the build server delete the old working copy and check out a fresh copy to avoid any problems with stale artifacts from the previous build.
Next I would have nant or msbuild build the solutions as before with the artifacts from each build going to their local working output folders.
After that I'd move the artifacts from their working paths to their output paths, this shouldn't require digging through the project files since you can just tell msbuild/nant to copy working\project1\bin\release\**\*.* to artifacts\project1\.
The script that does this should ideally be stored along with the source with the main file, e.g. build.nant or build.proj in top level of the trunk.
For third party libraries I would simple include the DLLs directory in your repository. Nothing worse than writing some code and having a third party dependency break your build because of changes on their end.
Simply document the versions of the libraries you are using, and if you must update them, you'll have a better sense of what breaks the build before you even check it in.
Also, doesn't CC.Net automatically handle the providing of releases based on revision? I'm using TeamCity and it keeps a copy of the artifacts of every build.
I highly recommend reading JP Boodhoo's Automating Builds with NAnt blog series. That's been my starting point and have made lots of changes for my own taste. I also highly recommend checking out the builds of many open sources projects for examples. I've learned a lot from the builds of the Castle/Nhibernate/Rhino-Tools stack.
