Post a Comment. However, since I work on a wide variety of projects as part of my consultancy, I frequently encounter projects which still leverage Visual Studio Post Build events. A large number of Visual Studio projects have a Post Build event which redirects the output to another directory on the file system and may even include a set of commands needed to create the correct target directory structure.
The problem with this approach is using standard command line commands such as mkdir will emit errors if a directory already exists, thus causing Visual Studio to raise an error if a particular command in the Post Build event fails even though it may have worked just fine overall. So, how do you handle this problem? Well, using the capabilities of MSBuild, you can modify the Visual Studio project file to ignore these Post Build event error messages!
Alternatively, you can even do both! Once you include this target in your relevant Visual Studio project files, the Post Build event error messages you are encountering should disappear! No comments:. Newer Post Older Post Home. Subscribe to: Post Comments Atom.A build event is a command that MSBuild performs at a particular stage in the build process.
The pre-build event occurs before the build starts; the pre-link event occurs before the link step starts; and the post-build event occurs after the build successfully ends. A build event occurs only if the associated build step occurs. For example, the pre-link event does not occur if the link step does not run. Each element is optional, and if you specify the same element multiple times, the last occurrence takes precedence.
The value of the content of a use-in-build element is either true or false. By default, a build event is executed unless its corresponding use-in-build element is set to false. The following example can be added inside of the Project element of the myproject. A pre-build event makes a copy of main. If the project is built using a release configuration, the build events are executed.
If the project is built using a debug configuration, the build events are not executed. You may also leave feedback directly on GitHub.

Build events execute only if the build successfully reaches those points in the build process. When a project is built, pre-build events are added to a file named PreBuildEvent.
If you want to ensure error checking, add your own error-checking commands to the build steps. In Solution Explorerselect the project for which you want to specify the build event.
In the Post-build event command line box, specify the syntax of the build event. Add a call statement before all post-build commands that run. In the Run the post-build event box, specify under what conditions to run the post-build event. The build event syntax can include any command that is valid at a command prompt or in a. The name of a batch file should be preceded by call to ensure that all subsequent commands are executed. If your pre-build or post-build event does not complete successfully, you can terminate the build by having your event action exit with a code other than zero 0which indicates a successful action.
The following procedure shows how to set the minimum operating system version in the application manifest by using an. The minimum operating system version is a four-part number such as 4. Create a new Console App project for the command. In Program. The command takes two arguments: the path of the application manifest that is, the folder in which the build process creates the manifest, typically Projectname. With the project selected in Solution Exploreron the Project menu, choose Properties.
To view the manifest, right-click the file, click Open withselect Select the program from a listand then click Notepad. For example, the version might be:.
When you build the project, this command changes the minimum operating system version in the application manifest to 5. Publishing copies this manifest to the publishing location that you set earlier. You may also leave feedback directly on GitHub. Skip to main content. Exit focus mode. Specify a build event In Solution Explorerselect the project for which you want to specify the build event.Working on a large application can uncover some unique issues. Learning how everything is organized, built, referenced and such - can be challenging to say the least.
In my experience with such an application, I came across an issue with using oost-build events, but only when using MSBuild. This works as expected when you build a solution or project from within Visual Studio. However, it broke the full application build. However, when we run the MSBuild build, it is executed from a different directory… which means that all of the post-build events that exist in any of the projects being built will be executed from that directory as well.
However, we can workaround this problem, and essentially ignore the post-build event while running MSBuild. Remember that the Post-build event command is really just a place to put DOS commands that get executed after a successful build. This means that we can use some DOS variables. Then, add a variable in the batch file before you call the MSBuild process.
Something like this:. Then, you need to modify your post-build event to only do something if the variable is not set, or has the wrong value:. The TargetFileName Whatever. But, when you build using your new batch file - it will not execute the command after the IF statement.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

In SDK projects, the final targets import is implicit, so the event properties get added to the body of the project, and end up with empty values if they try to reference most of the standard build properties.
We've got lots of bugs around this internally, devs use these tabs - removing them doesn't solve the problem. Convinced that we should replace these with targets. We're also not roundtripping the value that the user enters: Are you sure this isn't related to you running over a different kind of binary.
NET Core that the obfuscation tool doesn't recognize? NET Core 1. It was no need in adding Sdk. But now I get " warning MSB " It was already imported at " This is most likely a build authoring error. This subsequent import will be ignored.
The project file was created by VS as. I compile the project with VSso not sure how it handles msbuild and donet sdk under the hood. Please find the file attached proj.
Changed it to Microsoft. Webrather than Microsoft. Sdk as it was before. Get a similar message: " warning MSB " You need to remove the SDK attribute - the explicit Imports effectively doing the same thing as it. Sorry, I'm really slow on the uptake. Yes, it helps and removes all the warnings. Thank you very much! Could you please clarify the status of this issue and the fix? I am using VS AKlaus The fix for this issue does not change your existing property logic so you should move your events into a target as blumu suggests.
This reported issue directs people here. If I'm reading this correctly, its not yet fixed, and the workaround requires unloading and editing the csproj file instead of using the UI.

View All. Gaurav Gahlot Updated date, Aug 02 Think of a scenario where we build our library project and its. For some reason, we want all our library files in one common directory that we would refer somewhere in our project. One way to do it is to manually copy the library files from their respective release or debug directories into the desired directory. Just kidding! We obviously don't want to do that.
Pre build events, on the other hand, are used when we want an operation to be performed before the build starts. These build events are composed of the Shell commands similar to the following one. Assume that the above line of code is a post build event. The event will copy the targeted files from the project directory into the Library directory, which resides in the main directory.
Let's have a closer look at the command line event in parts. Similarly, we can use other commands as well. For example, we can use move instead of copy.
This is the directory from where we wish to extract our files. Visual Studio provides a list of macros that we can use while creating our build event command. You may read more about the available macros here. If the value of TargetExt is not what we want, we can simply replace the macro with our own extension. If we know the file name we can use the file name with the target extension and that file will be copied to the desired location. In the sample command, I have used the project directory, however we can always replace it with other available macros as per our need.
Because I want to store my desired files into the Library directory which lies in the main directory, I have used ". When the build event is triggered, we can see the actual command executed by Visual Studio in the background, in its output window. We can execute multiple commands in our build event. All we need, is to add a new line between the two commands.
