Build succeeded with projects Ctrl + Shift + B that MSBuild can't build

Question

Does anyone know where I can take a look at my project if after I make a build with MSBuild through MSBuild console I get this warning:

MSB4078: The project file 'MyProject.csproj' is not supported by MSBuild and cannot be built?

My project is running with Target Framework .Net Core 2.0. The MSBuild version I am using is 14.0.25420.1

This is the cs.proj

Answer 1

You are using the new csproj file format (see Project sdk=...)

You will need to use MSBuild 15 in order for it to build. You have two options:

1) Download Build Tools for Visual Studio 2017 and install. Then the path will be:

C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin

2) If you have VS installed, the path will be:

C:\Program Files (x86)\Microsoft Visual Studio\2017\<VS Version>\MSBuild\15.0\Bin

Using MSBuild 15 should fix the error.

Answer 2

Please check what version of MSBuild are you running. I tested with the version 15.0, it runs without any error.

Generally, make sure that you have configured a build agent for your team project, and that you have Visual Studio 2017 installed on the agent machine and that you installed the latest Visual Studio update.

Also make sure you have select the MSbuild version 15.0 for the build.

See Build your ASP.NET Core app for details.

Answer 3

I suggest to use MSBuild in more reliable way.

1. Download Build Tools for Visual Studio 2017 from Visual Studio Downloads page, it includes latest MSBuild 15.* (direct link).

   Command-line arguments documented here: Use command-line parameters to install Visual Studio 2017.

   All workloads and components are listed here: Visual Studio Build Tools 2017 component directory.

2. Use PowerShell module VSSetup to find MSBuild. Download it or install from here: Github: Microsoft/Visual Studio Setup PowerShell Module

Find MS Build

Import-Module $PSScriptRoot\VSSetup\VSSetup.psd1

$msBuildPath = (Get-VSSetupInstance | Select-VSSetupInstance -Version 15.0 -Product Microsoft.VisualStudio.Product.BuildTools).InstallationPath

if ([System.IntPtr]::Size -eq 8)
{
    $global:msbuildPath = Join-Path $msBuildPath 'MSBuild\15.0\Bin\amd64'
}
else
{
    $global:msbuildPath = Join-Path $msBuildPath 'MSBuild\15.0\Bin'
}

Write-Output "Using MSBuild from $global:msbuildPath"
Write-Output "MSBuild /version"

$msbuild = Join-Path $global:msbuildPath msbuild

& $msbuild /version
