Nothing else 'csc' works on Mono

Mono is a set of build tools. Before and after version 5.0, Mono tools never worked, except% with%. To clarify, although the version is not related to the problem, since the version 5.0 Mono integrated .NET tools such as csc , msbuild etc. and obsoletando some ( nuget and maybe more). Mono also has the xbuild tool that does not work correctly even today ... Everything from Windows 8 (.1) to Windows 10, to me Mono never did anything.

mkbundle exports applications to executables, installers, etc. Now it works instead of exporting error, but it generates failed executables that print mkbundle instead of Error mapping file: No error .

Olá, mundo! failed with:

And here's my CSProj, according to documentation :

<Project DefaultTargets='Build' xmlns='http://schemas.microsoft.com/developer/msbuild/2003'>
    <PropertyGroup>
        <AssemblyName>TurboCS</AssemblyName>
        <OutputPath>target</OutputPath>
    </PropertyGroup>
    <ItemGroup>
        <Compile Include='src/*.cs'/>
    </ItemGroup>
    <Target Name='Build'>
        <MakeDir Directories="$(OutputPath)" Condition="!Exists('$(OutputPath)')"/>
        <Csc Sources="@(Compile)" OutputAssembly="$(OutputPath)$(AssemblyName).exe"/>
    </Target>
    <Target Name='Clean'>
        <Delete Files="$(OutputPath)$(AssemblyName).exe"/>

Any ideas?
