This is a problem I've been struggling to solve for a while. I need a way to either replace code in the method with a parsed code from the template at compile time (PostSharp comes to mind) or to create a dynamic proxy (Linfu or Castle). So given a source code like this

[Template]

private string GetSomething()

{

var template = [%=Customer.Name%]

}

I need it to be compiled into this

private string GetSomething()

{

MemoryStream mStream = new MemoryStream();

            StreamWriter writer = new StreamWriter(mStream,System.Text.Encoding.UTF8);

writer.Write(@"" );

writer.Write(Customer.Name);

StreamReader sr = new StreamReader(mStream); 

writer.Flush();

mStream.Position = 0; 

return sr.ReadToEnd();

}

It is not important what technology is used. I tried with PostSharp's ImplementMethodAspect but got nowhere (due to lack of experience with it). I also looked into Linfu framework. Can somebody suggest some other approach or way to do this, I would really appreciate. My whole project depends on this.
