The provided C# code appears to be a set of Git commands rather than C# code. These commands are used to track certain file types with Git LFS (Large File Storage) and to add the `.gitattributes` file to the staging area in Git.

Since this is not C# code, it cannot be directly converted to VB.NET. If you have any C# code that you would like to convert to VB.NET, please provide it, and I will be happy to assist with the conversion.
