T4 code generation: access types in current project

Question

Using T4 code generation, is it possible to access the types defined in the current project?

For example, if I have an interface and I want to delegate its implementation to another class, i.e.

interface IDoSomething {
    public void do_something();
}

class DoSomethingImpl : IDoSomething {
    public void do_something() {
        // implementation...
    }
}

class SomeClass : IDoSomething {
    IDoSomething m_doSomething = new DoSomethingImpl();

    // forward calls to impl object
    public void do_something() {
        m_doSomething.do_something();
    }
}

I would like to automate the call-forwarding in SomeClass with code generation; is this possible?

While this doesnt solve the locking problems (although ive heard that VS2010 does), you could try copy the dll to a temp location and just use that copied assembly..

<#@ template debug="false" hostspecific="false" language="C#" #>
<#@ output extension=".txt" #>
<#@ import namespace="System.Reflection" #>
<#@ import namespace="System.IO" #>
<#    
var newFileName = System.IO.Path.GetTempFileName();
System.IO.File.Copy(@"C:\Development\CustomAssembly.dll",newFileName,true);

var assembly = Assembly.LoadFrom(newFileName);
var type = assembly.GetType("CustomAssembly.DummyClass");   
#>
<#=newFileName#>
<#=type#>
