Visual Studio C# project in Monodevelop - Errors for GenerateSatelliteAssemblies and GenerateTargetFrameworkMonikerAttribute

I am trying to setup a C# project that is compatible with both Windows 10 / Visual Studio 2015 and Ubuntu 16.04 / MonoDevelop.
In the MonoDevelop project options, I set the target framework to Mono / .NET 4.5 and configuration to Debug|x86.

The .csproj file now looks like this:

<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration>
    <Platform Condition=" '$(Platform)' == '' ">x86</Platform>
    <ProjectGuid>{myprojectsguid}</ProjectGuid>
    <OutputType>Exe</OutputType>
    <RootNamespace>myproject</RootNamespace>
    <AssemblyName>myproject</AssemblyName>

  </PropertyGroup>
  <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x86' ">
    <DebugSymbols>true</DebugSymbols>
    <DebugType>full</DebugType>
    <Optimize>false</Optimize>
    <OutputPath>bin\Debug</OutputPath>
    <DefineConstants>DEBUG;</DefineConstants>
    <ErrorReport>prompt</ErrorReport>

  </PropertyGroup>
  <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x86' ">
    <DebugType>full</DebugType>
    <Optimize>true</Optimize>
    <OutputPath>bin\Release</OutputPath>
    <ErrorReport>prompt</ErrorReport>
    <WarningLevel>4</WarningLevel>
    <Externalconsole>true</Externalconsole>
    <PlatformTarget>x86</PlatformTarget>
  </PropertyGroup>
  <ItemGroup>
    <Reference Include="System" />
  </ItemGroup>
  <ItemGroup>
    <Compile Include="Program.cs" />
    <Compile Include="Properties\AssemblyInfo.cs" />
  </ItemGroup>
  <Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
</Project>

When I build, I get this message:

Erzeuge Projektmappe: myproject (Debug|x86)

myproject (Debug|x86) wird erzeugt

The message seems to contradict itself. The English part says "build failed", while the localized/German part says "build successful". But no executable was created.
I did not find any applicable information about GenerateSatelliteAssemblies or GenerateTargetFrameworkMonikerAttribute.
Do I need to change the project settings even further? Do I need to supply some missing files?

Update:
Apparently, some packages were missing. So I ran sudo apt-get install mono-complete. Now the project builds successfully.
Though, the notifications about GenerateSatelliteAssemblies and GenerateTargetFrameworkMonikerAttribute are still there. Looks like they don't break the build. I still wonder what they mean.
