Add Clean script to MsBuild

Add the following Target to the Project.csproj file :

    <Target Name = "Clean">
        <RemoveDir Directories="$(builtdir)" />
    </Target>

We will have to declare what is builtdir (which will be pointing to something like bin) and for this we will have to add 

<builtdir>BuiltApp</builtdir>

and to create a new directory during build process

<MakeDir Directories = "$(builtdir)" Condition = "!Exists('$(builtdir)')" />

Now to clean use the following

msbuild <file name>.proj /target:Clean

and to build use

msbuild <file name>.proj /target:Build
