Microsoft.WebApplication.targets

Harvey Colasino 6

After I setup my workflow in GitHub for building and deploying my project to Azure, I'm getting this error:

"C:\Users\runneradmin\AppData\Local\Microsoft\dotnet\sdk\5.0.406\Microsoft\VisualStudio\v15.0\WebApplications\Microsoft.WebApplication.targets" was not found. Confirm that the expression in the Import declaration "C:\Users\runneradmin\AppData\Local\Microsoft\dotnet\sdk\5.0.406\Microsoft\VisualStudio\v15.0\WebApplications\Microsoft.WebApplication.targets" is correct, and that the file exists on disk.

I tried the following suggestion from the article:

https://alastaircrabtree.com/microsoft-webapplication-targets-was-not-found-again/

Can anyone help?

Thank you

Hi @HarveyColasino-5251 , you need to check if this Microsoft.WebApplication.targets file exists. If it doesn’t exist, you need to get(install) it. Assume you use VS Installer and have VS Build Tools, then you can try to install Web development build tools workload from VS Installer for VS Build Tools 2017.

Hi Microsoft or @tianyusun-msft,

I am also running into this same exact issue. I am new to Microsoft Visual Studio and I am using Mac. Here is the path I took and the runtime environment I am coming from.

Using MacOS Ventura (13.x)

Installed Visual Studio for Mac, v 17.5.2 (build 14) - Community license

Installed Mono project for Visual Studio for Mac 6.12.0 Stable (6.12.0.182)

My class project team member is using Visual Studio Enterprise Edition for Windows 11, where he created the WebApplication using C# and committed to our Git repo.

When I cloned the Git repo and attempt to run, I received the same runtime dependency error message as the OP.

After many internet search attempts, according to this blog post, it seems to imply this WebApplication component can only be installed from Professional or Enterprise Edition of Visual Studio. Is this a valid assumption in 2023 for Mac? If this is no longer true, can you please provide a reference or how-to guide to install this web component runtime dependency?

In the Github mono repo, this Microsoft.WebApplication.targets was last committed on Jan 8, 2014. However, not much documentation provides how to build or install this runtime dependency.

I can not find the Mac version of the Build Tools for Visual Studio 2022. Can you please share the Mac version installer location?

According to this Microsoft Visual Studio for Mac forum post, this was some how fixed in Mono Framework Stable Release: 15.2.2 Servicing Release on May 23, 2017. However, this 15.2.2. version string does not conform to the Mono release version string for Mac I installed in the above point #3 6.12.0.182.

According to Microsoft Visual Studio 2022 Build tools component directory documentation, it indicates it does NOT applies to Visual Studio for Mac.
This is the exact error message I am trying to resolve:

Error MSB4019: The imported project "/Library/Frameworks/Mono.framework/Versions/6.12.0/lib/mono/xbuild/Microsoft/VisualStudio/v17.0/WebApplications/Microsoft.WebApplication.targets" was not found. Confirm that the expression in the Import declaration "/Library/Frameworks/Mono.framework/Versions/6.12.0/lib/mono/xbuild/Microsoft/VisualStudio/v17.0/WebApplications/Microsoft.WebApplication.targets" is correct, and that the file exists on disk. (MSB4019) (WCA)

Thank you for any official insights on how to overcome this runtime dependency.

I too am awaiting a solution. I copied the file to the exact folder it is looking for, and have checked my spelling about 20 times. It is there. Still says not found.

I want to preface this by saying, this solution does not feel right, but does seem to work.

I found this article from Microsoft and installed web tools

dotnet workload install wasm-tools-net6

Then I went to the location called out by the error and copied the WebApplications folder from v16.0 to v17.0

cd /lib/mono/xbuild/Microsoft/VisualStudio/ sudo cp -r v16.0/WebApplications v17.0

There should be a more official way to handle this, but this at least got me to a point where I could build projects at work again
