Answer 1

msbuild 15 is not used by default. You can use it, with a little modification to your Kudu script.

Here is an example using msbuild 15 for restore, build and publish*.

:: 1. Restore nuget packages
call :ExecuteCmd nuget.exe restore "%DEPLOYMENT_SOURCE%\BACON.sln" -MSBuildPath "%MSBUILD_15_DIR%"
IF !ERRORLEVEL! NEQ 0 goto error

:: 2. Build and publish
call :ExecuteCmd "%MSBUILD_15_DIR%\MSBuild.exe" "%DEPLOYMENT_SOURCE%\BACON.WEB.csproj" /p:DeployOnBuild=true /p:configuration=Release /p:publishurl="%DEPLOYMENT_TEMP%" %SCM_BUILD_ARGS%
IF !ERRORLEVEL! NEQ 0 goto error

* change BACON.sln & BACON.WEB.csproj to your project file names
