C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets(132,11):
error MSB4064: The "Retries" parameter is not supported by the "Copy" task. Verify the parameter exists on the task, and it is a settable public instance property.

After some debugging i realized that Visual Studio 2010 had changed a line in the csproj file of my web application project.

From:

To:

I just had to change this line back to v9.0 to get it to work again. Hopefully this can help someone that has the same problem as me.

UPDATE!

Now when the RTM of Visual Studio was released i of course ran into this problem again. This time i tried to find a better solution and found this post on devlicio. In the comments to that post i found a solution that worked great for me.

I had the same issue. I had to alter the MSbuild WebApplication file located: C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications and remove these entries.

Retries=”$(CopyRetryCount)”

and          RetryDelayMilliseconds=”$(CopyRetryDelayMilliseconds)”

Once both of these were removed (in 13 places) everything worked fine. Hope it helps you too.

Anyway i started to look at MSBuild and see if it could handle my Publish task and i found this great article. It explains how to make a build file that build your project and then also simulate the publish feature and put just the files necessary into a separate folder.

While i was on the subject i thought that i could as well see if i could set up my source control machine to build my app as soon as i check in some files, copy the build to a folder and make that folder a web application.

I actually was kind of easy. I found an article by Omar Al Zabir that explains this in great detail.

Not any problem at all?

Ofcourse. The one i had most problem with was the infamous Microsoft.WebApplication.targets bug. When you build your project on the build machine you get this error.

error MSB4019: The imported project “C:\Program Files\MSBuild\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets” was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.

I have had this problem before when we migrated a “Website” to a “Web application project” at my last job. What i remembered from it was that you had to copy the file Microsoft.WebApplication.targets from it’s location on your dev machine to the build machine. Well fine. The problem in my case was that the file already was there. I looked around for maybe an hour or until i realized that the path on my build machine was:

C:\Program Files\MSBuild\Microsoft\Visual Studio\v9.0\WebApplications\Microsoft.WebApplication.targets

While on my dev machine it was:

C:\Program Files\MSBuild\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets

Notice the difference? Don’t you just love Microsoft sometimes .. just copy the path and remove the space from “Visual Studio” and it works.

That was actually the only major problem i had. Otherwise i used my brain and the articles i linked to and everything is happy puppy.

Thanks and good night.
