You could get the error if you enabled Sign the ClickOnce manifests and the .pfx file specified for ClickOnce manifest signing could not be found in your certificate store when MSBuild was trying to publish the manifest.

To resolve this error, try re-importing the .pfx file again in the certificate store. To re-import the .pfx file, right-click the .pfx file in Windows Explorer and choose Install PFX.

I created a new Console Application that was built and working as expected using visual studio 2022. However, when I build an application on another version of Visual Studio such as Visual Studio 2015 with a different version of the framework, I receive this error "Unable to find manifest signing certificate in the certificate store".

If you get a compilation error saying "Unable to find manifest signing certificate in the certificate store." right click on Ifs.Prjmsp.Cloud then select properties and then create a test certificate.

Unless a customization has been done, setup is signed with a valid R & D certificate. If you get warning saying "Unknown Publisher" and does not proceed with the application, install *Digicert* Intermediate certificate in the end user machine.

@Sri-Boddupalli While I'm not sure about the syntax (I normally use an external pfx file instead of the certificate store), so I'm not sure of syntax for getting from the store. But consider these ideas:

Subject Name matched with Manifest file CN name verified it. Just to reassure I exported the certificate installed by our team in the store as a .cer file and imported it during the MSIX pacakging process. Which do not sign the package but automatically generates the correct publisher information.

One thing I noticed is it does not have .MSIX file in the drop down selection of file type we are signing shown in below. Does this mean our code signing certificate is not supporting MSIX file type? after all the error message we got while using the signtool was "The file format cannot be signed because it is not recognized"

If the Digicert utility doesn't recognise .msix, you can try renaming the file to .appx and then sign it. Ultimately I assume this utility is calling the Microsoft signtool.exe utility to perform the signing.

(1) Start with testing if the certificate you have is valid for code signing. Are you able to sign any executable with it? (download 7-zip EXE from the official website and try to sign it). If you get an error at this point, then there is something probably wrong with your certificate. After all, one of the error codes your reported was

(2) If signing works for EXE, then it should (with the version you have) work for MSIX as well. You should try to validate your MSIX then - how did you create it? Can you use makeappx.exe to unpack it, and then pack it again? It should do some semantic validation to ensure that the manifest is correct and some values are in place.

It was so frustrating to fight with AD team on getting the .PFX file with Password. I understand their security concerns but without that we are pretty much helpless. @John Vintzel @ShakersMSFT Any better explanation I can come up with, if our AD team ask why exactly we need .PFX file instead of installing the certificate in cert store and using that? OR if you could develop a Signtool GUI utility that would be wonderful

I am trying to build a vdproj file using devenv. I have read several post that explain how I can do it by embedding a task in the project file and having it invoke devenv. I'm trying to build the project outside of visual studio using a CI tool. My concern with adding this code into the project file is how somebody is effected building it within visual studio.

I have a really odd and hard to diagnose issue with MSBuild / TFS. I have a solution that contains about 12 different build configurations. When running on the build server, it takes maybe 30mins to build the lot and has worked fine for weeks now but now is occasionally failing.

The error will sometimes happen on a different file. It won't happen for every build configuration either, it's very inconsistent and occasionally even builds all of them successfully. There's not much different between the build configurations either, mostly it's just a few string changes and of course they all build locally just fine.

We have a line of business app which is deployed via clickonce. I can build and publish the application without any problems but when I try to use Continuous Integration (Build each check-in) I get the following error:

The Certificate is stored in Certificate store on my local workstation. The Certificate is also in the certificate store of the build server (1. In the Personal Store, 2. in the Personal store of the TFSBuildServiceHost Service Account and 3. in the Personal store of the tfs/build server itself).

I'm trying to make a .targets file for my NuGet package, which will link to a proper .lib file depending on the C++ runtime library of a project. This answer recommends to use %(ClCompile.RuntimeLibrary) metadata for this. But I cannot use metadata in condition of the node. When trying to run MSBuild with the following test script:

The problem is that I am seeing many warnings when I build this project related to the MSBuild Microsoft.Common.CurrentVersion.targets file. The project actually seems to run, but there are more than 100 warnings all coming from the targets file.

I am setting up environment for building hadoop code in windows 8.1. This needs CPP compilers (v120/V110), I installed windows SDK successfully but I still dont see MSBuild/Microsoft.Cpp created. I tried with windows SDK 7 and 8 also. It looks like none showing up this.

My problem looks like this: I need to use a dll in a java application through JNI. I have 2 dll libraries build from EXACTLY the same code. The first one is built by somebody else on another machine and the second one is built by me on my machine.

I have a VS Package (C#) project that builds fine from within Visual Studio. I want to be able to build from the command line. I know that I need tocall "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\vsvars32.bat" and set the VSSDKInstall environment variable.

(I know that "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VSSDK" is not the right path, as that causes the command line to not build and furthermore causes Visual Studio IDE to no longer build.)

However, I have to build certain projects using PlatformToolset=v110 (Visual Studio 2012), and prefer to do the development under VS 2013 (single mixed project solution). The PreferredToolArchitecture property does not work, and build falls back on using the 32-bit compiler stack for these projects. Neither does setting _IsNativeEnvironment=true work.

Hi, I have a question regarding the difference I have noticed when building a solution file using MSBuild from command line and when doing it inside Visual Studio 2013 Update 4. The solution file I am using contains a lot of projects.

In this scenario, after successfully building the solution file, if I try to build it again, then MSBuild notifies me that the projects are up-to-date and it doesn't try to compile any source files, which is evidently the expected behavior. But it actually tries to execute or goes through the targets in the Build step trying to determine whether the Output files are out-of-date. And this occurs for every project that is existent in the solution. Even though it doesn't build the solution again, the process of checking time stamps of files for each project actually takes quite a long time.

When doing it inside Visual Studio, after a successful build, if I try to build the solution again, then it automatically notifies me that the projects are up-to-date. It actually takes few seconds to return this output. Looking at the build output, I noticed Visual Studio doesn't really execute targets to conclude that the projects are up-to-date. So I figured it must be using something different to check the statuses of the projects.

I really want to bridge the performance gap between these two "worlds". I would really appreciate any help or hints in regards to how Visual Studio is performing this check or ways I could implement something similar in MSBuild.

Code signing is a procedure that verifies the legitimacy of the author and the originality and authenticity of digital information, particularly software code. It also ensures that the information is not malicious code. Additionally, it guarantees that this information has not been altered, falsified, or canceled after being digitally signed.

Your projects developed in Visual Studio with Visual Basics and Visual C# can be published and updated using ClickOnce. ClickOnce is a Microsoft technology used to deploy and update Windows desktop applications over the internet. It allows developers to publish their applications on a web server or network file share and make them available to users via a single click without any complex installation or configuration process.

While you publish your project using ClickOnce, you can sign ClickOnce manifests using a certificate. This will help prove the legitimacy of your application, and this process is called Code signing. Codesigning with ClickOnce provides several security features to ensure that the application and its updates are downloaded from a trusted source and that users are protected against potential security threats. It adds an extra layer of security to your application and can help increase user trust.
