The following is so so simply and yet it fails. What's wrong?
I create a new ASP.NET Core Web Application (.NET Framework 4.6.2) in Visual Studio 2017.
I make no changes to the default template and I push it to VSTS.
I create a new build definition in VSTS with the following two steps:
- NuGet Restore
- Visual Studio Build
I update the NuGet step to use version 4.0.0
I update the definition to use the Hosted VS2017 agent.
I leave the Build step using VS2017 with the default MSBuild arguments:
/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:PackageLocation="$(build.artifactstagingdirectory)\\".
In previous versions this would create me a web deployment package which is exactly what I want.
- I queue a new build.
The NuGet step succeeds.
The build step runs until it logs...
_TransformWebConfig:
...and then...
No web.config found. Creating 'C:\a\1\s\src\WebApp\obj\Release\net462\win7-x86\PubTmp\Out\web.config'
...and...
Microsoft.NET.Sdk.Publish.MSDeployPackage.targets(124,7): Error MSB4184: The expression "[System.IO.Path]::GetDirectoryName('')" cannot be evaluated. The path is not of a legal form.
