Is there any MSBuild alternative?

[DrMAF]

**I'm an under training student with so few experience of C#.
Our company is developing a solution using T4 templates (C# VS2010).
The generated files can't be compiled under MSBuild because it is VS dependent.
My task is to find a tool or a library or a .dll file or SDK or any thing that can replace VS in building time. Other wise I have to modify the generated code to be VS independent my selef, which I think is a diffucult task for me.
code samble:

Project GetProjectContainingT4File(DTE dte) {

    // Find the .tt file's ProjectItem
    ProjectItem projectItem = dte.Solution.FindProjectItem(Host.TemplateFile);

    // If the .tt file is not opened, open it
    if (projectItem.Document == null)
        projectItem.Open(Constants.vsViewKindCode);

    if (AlwaysKeepTemplateDirty) {
        // Mark the .tt file as unsaved. This way it will be saved and update itself next time the
        // project is built. Basically, it keeps marking itself as unsaved to make the next build work.
        // Note: this is certainly hacky, but is the best I could come up with so far.
        projectItem.Document.Saved = false;
    }

    return projectItem.ContainingProject;
}

I would appreciat your help.**
