When you use MSBuild. The documentation only shows the -switch form. Switches are not case-sensitive. If you run MSBuild from a shell other than the Windows command prompt, lists of arguments to a switch separated by semicolons or commas might need single or double quotes to ensure that lists are passed to MSBuild instead of interpreted by the shell.

The following example builds the rebuild target of the MyProject. You can use MSBuild. For example, you can use it to build specific targets of specific projects in a solution. You may also leave feedback directly on GitHub. Skip to main content. Exit focus mode. Syntax MSBuild. If you don't specify a project file, MSBuild searches the current working directory for a file name extension that ends in proj and uses that file.

You can also specify a Visual Studio solution file for this argument. Switches Switch Short form Description -detailedSummary -ds Show detailed information at the end of the build log about the configurations that were built and how they were scheduled to nodes.

Constructing a graph involves identifying project references to form dependencies. Building that graph involves attempting to build project references prior to the projects that reference them, differing from traditional MSBuild scheduling. The following command is an example: msbuild. Use a semicolon or a comma to separate multiple extensions, as the following example shows: -ignoreprojectextensions:. Do not use this argument in an automated scenario where interactivity is not expected.

Specifying -interactive is the same as specifying -interactive:true. Use the parameter to override a value that comes from a response file.

This is a more restrictive mode of MSBuild as it requires that the project graph be statically discoverable at evaluation time, but can improve scheduling and reduce memory overhead when building a large set of projects. If you don't include this switch, the default value is 1. If you include this switch without specifying a value, MSBuild will use up to the number of processors in the computer.

For more information, see Building multiple projects in parallel. The following example instructs MSBuild to build using three MSBuild processes, which allows three projects to build at the same time: msbuild myproject.

You can specify the following values: - True. Nodes remain after the build finishes so that subsequent builds can use them default. Nodes don't remain after the build completes. A node corresponds to a project that's executing. If you include the -maxcpucount switch, multiple nodes can execute concurrently. You can use this switch to more easily determine which files are being imported, from where the files are being imported, and which files contribute to the build.

When you use this switch, the project isn't built. If you specify a filepaththe aggregated project file is output to the file. Otherwise, the output appears in the console window. For information about how to use the Import element to insert a project file into another project file, see Import element MSBuild and How to: Use the same target in multiple project files.Whether you're building from the Visual Studio IDE, or setting up a command-line build, you need to know how Visual Studio uses the Dockerfile to build your projects.

For performance reasons, Visual Studio follows a special process for containerized apps. Understanding how Visual Studio builds your projects is especially important when you customize your build process by modifying the Dockerfile. When Visual Studio builds a project that doesn't use Docker containers, it invokes MSBuild on the local machine and generates the output files in a folder typically bin under your local solution folder.

For a containerized project, however, the build process takes account of the Dockerfile's instructions for building the containerized app. The Dockerfile that Visual Studio uses is divided into multiple stages. This process relies on Docker's multistage build feature. The multistage build feature helps make the process of building containers more efficient, and makes containers smaller by allowing them to contain only the bits that your app needs at run time.

Multistage build is used for. NET Core projects, not. NET Framework projects. The multistage build allows container images to be created in stages that produce intermediate images. As an example, consider a typical Dockerfile generated by Visual Studio - the first stage is base :. You can see that the build stage starts from a different original image from the registry sdk rather than aspnetrather than continuing from base.

The sdk image has all the build tools, and for that reason it's a lot bigger than the aspnet image, which only contains runtime components.

The reason for using a separate image becomes clear when you look at the rest of the Dockerfile:. This process makes it possible for the final image to be a lot smaller, since it doesn't need to include all of the build tools that were in the sdk image. If you want to build outside of Visual Studio, you can use docker build or MSBuild to build from the command line.

You provide the build context argument. The build context for a Dockerfile is the folder on the local machine that's used as the working folder to generate the image. For example, it's the folder that you copy files from when you copy to the container.

NET Core projects, use the folder that contains the solution file. Expressed as a relative path, this argument is typically ". NET Framework projects, the build context is the project folder, not the solution folder. Dockerfiles created by Visual Studio for.

Developer Community

NET Framework projects and for. The steps in these Dockerfiles do not compile your code. Instead, when Visual Studio builds a. When that succeeds, Visual Studio then builds the Dockerfile, which simply copies the build output from MSBuild into the resulting Docker image.

Because the steps to compile your code aren't included in the Dockerfile, you can't build. NET Framework Dockerfiles using docker build from the command line.

You should use MSBuild to build these projects. For example:. You'll see output similar to what you see in the Output window when you build your solution from the Visual Studio IDE. See Debugging. Here are the tasks that run in the background:. Warmup will only happen in Fast mode, so the running container will have the app folder volume-mounted.

That means that any changes to the app won't invalidate the container.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Problem description: When cloning and building using Visual Studio Preview 1, build. Minimal repro: clone and build under Preview 1.

I should note also that this issue does not occur with the WinForms repo. That build script appears to handle both situations e. Cc ericstj. The next PR should pick up all related changes and pass the new CI build, giving us the appropriate changes. See Wintermute21 If you've done work on top of a commit with your fix, you can interactively rebase on top of the latest update once it arrives and just delete that commit.

Otherwise, just be sure you don't commit your fix. Then you can pull the latest update when it arrives and resolve the conflict to pick up the latest. Btw, this is my first issue in an official MS repo and I appreciate how responsive people have been, especially so late at night.

Wintermute21 It's my first official MS repo that I'm directly involved with, excitement all around! I'll start to look at it when I get in this morning. Wintermute21 Can you retry your build without your workaround and confirm you're good to go? Wintermute21 Closing as everything seems to work now.

Thanks you very much! NET Development Chicago cmscentral. NET, Sitecore and setup development. Monday, October 29, A solution can build fine from inside the Visual Studio, but fail to build with msbuild.

Today I have faced with an interesting issue.

msbuild fails when visual studio succeeds

Although I failed to reproduce it on a fresh new project, I think this info might be useful for others. I have a solution which was upgraded from targeting. NET Framework 2. NET Framework 3. The patch adds new files as well as modifies existing ones. After the patch application, the solution is successfully built from inside the Visual Studio, but fails to build from the command line with msbuild.

To look further into this, I took a look at the link. Note: the link. I suspect it must be an environment variable that is triggering this since the command line arguments match, possibly assigned in LIB?

In my case the root cause of this issue was old Nuget. Old version used old MsBuild v14 instead on v15 and it causes build issues after nuget restore. Try to update it with nuget. I can't seem to find anything in the restore logs or the package management logs in Visual Studio. ChristopherHaws I used nuget. Today I switched back to Restore target. When I used old nuget.

In VS build was working, but failed on the command line.

msbuild fails when visual studio succeeds

I cleaned up my repository with git clean -X -d -f command to verify every attempt to resolve this issue. After some time I noticed in the command line log that my old nuget.

So I tried to update nuget. Later today I switched to the Restore target and I removed nuget. It is working fine. Still the same behavior ChandraTerli Just create a file named build. Then call msbuild. This worked for me. Thank you! Instead, specify msbuild. The core problems with all of these approaches are the same: MSBuild tries very hard to avoid loading projects more than it needs to. That means that if you modify the project or create new imports, such as by restoring NuGet packages after the project has already started building, the rest of that build will not see the updated build logic, because it's already read from disk.

I'm not sure I understand the question aolszowka. Can you elaborate? Hi rainersigwald so we've got a lot of scripts that look something like this:.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Now if I clean and rebuild the same solution file from Visual Studio with the exact same configurations it will build successfully with no errors. Is there a difference in the setup or configuration of MSBuild from Visual Studio that needs to be changed that I am not aware of? After building it copies the files to this directory.

This explains why it works in visual studio and not msbuild I'm currently using TFS In my case I had an old binary version of a dll being referenced by a project that was being built after the one that should have generated the correct file. The old one binary was overwriting the new one built from source as the solution referencing the binary one was being built later in the build.

I assume there's a difference in how the project is built, because Visual Studio does not run MSBuild, as it rather hosts the build engine itself. This was answered here. In my case the project referenced an external library, which was placed in the project's child directory, unluckily named "packages".

After running MSBuild the folder's content was deleted, supposedly to be downloaded again by Nuget. Try checking the paths to the references that MSBuild can't find in the non-building library's project file.

VS seems able to cope with this, but MSBuild not so much. For me the problem was that the some projects in the solution were not included in the build configuration for the solution. Those projects were dependencies for the projects in the build configuration, so all the projects in the solution failed.

After marking the dependcies projects with build in the solution configuration the msbuild ran successfully. Made sure all related projects are indeed being referenced and not just liked to compiled dlls. Project B references A. Remove A from solution. Then add again. B would then reference A but via compiled dll only.

Remove reference and re-add the project. Finally switched to "Release" in Visual Studio. Turns out I had conditional compilation in some code eg. So what was running in MSBuild and Visual Studio were actually different hence the error "The type or namespace name 'foo' does not exist in the namespace 'bar' are you missing an assembly reference?

I fixed the problem by retargeting the PCL. Hope this helps somebody.
