title: What is a BLAT file (.blat extension)?
body: <p>I am building a Blazor WASM application and noticed a file with a &quot;.blat&quot; extension (dotnet.timezones.blat). The file is readable in a text editor and contains coded timezones and geographic information. I can infer the purpose of the file but am wondering what the meaning of BLAT is in this context. I have searched online and have only been able to learn that it is a new extension in .NET 5.0+. Any insights?</p>
  <p>(Note: I am assuming it is unrelated to the email console utility.)</p>
