I downloaded and installed the latest version of the T4 Toolbox for VIsual Studio 2010, in an attempt to create LINQ business objects, but I'm having some troubles with it. First, I was getting errors saying it couldn't find T4Toolbox.tt and T4Toolbox\LinqtoSql.tt in my project directory, but that's not where they are installed. Am I to provide the absolute path to them in my template?
In trying to get this to work, I removed the files I added via the instructions, and added them again. This time the error changed to "File doesn't exist: "\XML\SCHEMAS\DBMLSCHEMA.XSD". I have populated the dbml file using the server explorer.
Both errors reference the same file, the "ServerBiz.tt" file that I created from a Linq to SQL Model template in the Code Generation section in Visual Studio. They've also both generated the warning "The C# 2.0 and C# 3.5 compilers are no longer supported. Templates will always be compiled with the version 4 compiler instead of 'v3.5' as specified.", though switching the language attribute in the .tt file to "C#" cleared that up (and has had no effect on the errors I'm receiving). I've also got no color highlighting in the editor, though something tells me I just need to install a tool or something to get that to work. But I thought I'd mention these things in case they were relevant.
Update: I was mistaken, the search did find T4Toolbox.tt in C:\Program Files\T4 Toolbox. I've updated the post to reflect this.
