What is a .TT file?

A .TT file is a special kind of file known as a Visual Studio Text Template. Visual Studio is a program made by Microsoft that helps people create software. The .TT file is like a blueprint or a pattern that Visual Studio uses to make new text files. It's not just plain text, though. Inside a .TT file, there are parts that are regular text, which will appear just as they are in the new file. But there are also parts that are instructions or code, written in programming languages like Visual C# or Visual Basic. These instructions tell Visual Studio how to customize the new file it's creating.

For example, imagine you're making many invitations that all follow the same format but need different names on each. A .TT file could have the common parts of the invitation written out, and then use code to insert the different names wherever needed. This way, you don't have to write each invitation from scratch; the .TT file helps automate the process.

These .TT files are useful for two main things. First, they can help generate text files that are needed while a program is running. Second, they're used to create source code files, which are the building blocks of software. This makes .TT files very important for developers who are building complex applications, as it saves a lot of time and ensures consistency across multiple files.

To open and work with a .TT file, you would typically use Microsoft Visual Studio 2022 or a later version. Visual Studio understands the mix of text and code inside the .TT file and can process it to generate new files as intended. If you're working on software development or any project that involves generating lots of similar files, knowing how to use .TT files in Visual Studio can be very helpful.
