title: I can't build C# code with Monodevelop on Raspberry Pi
body: <p>I installed MonoDevelop on Raspberry Pi and copied one unit of project folder for C# which I had already written with VisualStudio2017 on Windows PC to Raspberry Pi. But, I can’t built(compiled) the source code with MonoDevelop.</p>
  
  <p>What should I do?</p>
  
  <p>Raspberry pi: CM3+(32GB) and CMIO<br>
  Raspbian:10(buster)  </p>
  
  <p>I installed MonoDevelop on Raspberry Pi and copied one unit of project folder for C# which I had already written with VisualStudio2017 on Windows PC to Raspberry Pi. But, I can’t built(compiled) the source code with MonoDevelop.</p>
  
  <p>What should I do?</p>
  
  <p>By the way, the following error message is output in MonoDevelop when building.</p>
  
  <blockquote>
    <p>[331
    Imported project
    “/Home/pi/,cache/MonoDevelop/7.0/MSBuild/1068_1/Microsoft.CSharp.Core.targets”
    Was not found.
    Check whether the  declaration path is correct, and whether the file exists on the disk. (MSB4019) '' ]</p>

  <p>(the original message is Japanese.)</p>
  
  <p>When I used <code>cd</code> and <code>ls</code> with CUI, I could not find <code>Microsoft.CSharp.Core.targets</code> in the folder <code>1608_1</code> (there were many files with similar names).</p>
  
  <p>By the way, executable file that I have already built on Windows PC works on Raspberry Pi.</p>
  
  <p>I would like to make a program roughly with VisualStudio on Windows PC and adjust fine debugging with MonoDevelop on the target machine, Raspberry Pi.</p>
