Question: I am currentlly in the process of writing a Cake build script to build a number of ASP.NET MVC sites. 

At the moment I am unable to see an option to pass arguments to MSBuild to produce the \_PublishedWebsites folder for deployment. 

I believe the arguments that I need to pass are:

```
/p:OutDir=$(build.stagingDirectory)
/p:DeployOnBuild=true
/p:WebPublishMethod=Package
/p:PackageAsSingleFile=true 
/p:SkipInvalidConfigurations=true 

```

If there is an alternative approach which produces the same output content just not in the same folder directory that would be fine.

Answer: 
The following example should set the correct MSBuild properties when building your website solution from Cake.

```
MSBuild("./src/Website.sln", new MSBuildSettings()
  .WithProperty("OutDir", "$(build.stagingDirectory)")
  .WithProperty("DeployOnBuild", "true")
  .WithProperty("WebPublishMethod", "Package")
  .WithProperty("PackageAsSingleFile", "true")
  .WithProperty("SkipInvalidConfigurations", "true"));

```

To set the output directory of the website, simply swap out the `"$(build.stagingDirectory)"` part with the path to the directory where you want the output to appear.

You can read more about the MSBuild alias in Cake here: <http://cakebuild.net/api/cake.common.tools.msbuild/>
For FileSystem publish it can be done this way:

```
MSBuild(/**project path**/, settings =>
    settings.SetConfiguration(/**configuration**/)
    .WithProperty("DeployTarget", "WebPublish")
    .WithProperty("DeployOnBuild", /**boolean**/)
    .WithProperty("PackageAsSingleFile", /**boolean**/)
    .WithProperty("WebPublishMethod", "FileSystem")
    .WithProperty("PublishUrl", /**url**/)
);

```
