Steps that work in my machine:
<ol>
<li>See <a href="https://stackoverflow.com/questions/58119480/visual-studio-prebuild-powershell-script-exiting-with-code-9009-and-failing-to-b/58127448#58127448">this</a>, first we need to make sure <code>MSBuild</code> can be recognized by <code>cmd.exe</code>.
</li>
<li>If the command can be recognized by <code>cmd.exe</code> but not build-event from VS, restart the PC can help resolve this issue.
(Something strange is that for my VS still can't recognize it until a restart of the computer)
</li>
<li>For VS2019, the correct msbuild path is <code>C:\Program Files (x86)\Microsoft Visual Studio\2019\xxx\MSBuild\Current\Bin</code>
</li>
</ol>
And here's another workaround:
Apart from adding the path of <code>msbuild.exe</code> into <code>Environment Path</code> and call it in <code>pre-build</code> event, you can also consider using <a href="https://docs.microsoft.com/en-us/visualstudio/msbuild/msbuild-task?view=vs-2019" rel="nofollow noreferrer">MSBuild Task</a>.
Add script below into <code>xx.csproj</code>:(work for .net framework...)
<pre><code> &lt;Target Name=&quot;MyCleanBeforeBuild&quot; BeforeTargets=&quot;BeforeBuild&quot;&gt;
 &lt;MSBuild Projects=&quot;$(ProjectPath)&quot; Targets=&quot;clean&quot;/&gt;
 &lt;!--&lt;Message Text=&quot;Custom Clean&quot; Importance=&quot;high&quot;/&gt;--&gt;
 &lt;/Target&gt;
</code></pre>

blocks|key|2695933|text|随着VS2019的最新更新-版本16.3.4+-错误不再存在。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2695934|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

With latest update to VS2019 - version 16.3.4 - the error is no longer there.

I am using VS2019 community and I've set pre-build event:

<pre><code>msbuild "$(ProjectPath)" /t:Clean
</code></pre>

I am getting error:

<pre><code> 'MSBuild' is not recognized as an internal or external command,
 operable program or batch file
</code></pre>

How is this possible? Isn't this command supposed to be build into visual studio?

I've checked <a href="https://stackoverflow.com/questions/6319274/how-do-i-run-msbuild-from-the-command-line-using-windows-sdk-7-1">this</a> and tried to set path environment, but it doesn't help.

Does anybody else has the same problem with this command in VS2019?
