This time, it’s a version of Template Toolkit for .NET. As usual, you can find the project on GitHub.

Not knowing anything about what it takes to convert a template language to .NET I started from ground up learning how to use ANTLR to create a lexer/parser automatically from a grammar definition. As if that wasn’t enough, my parser output is an Abstract Syntax Tree, which I then use another grammar to template it into C# code using StringTemplate templates, which ANTLR supports natively.

It’s slow going, but I’m learning a lot along the way. At some point I’m going to output VB.NET and it still needs a lot of work for compilation, dll caching and such. The code is in a pre beta state, but it does support basic GET/SET/DEFAULT/IF statements and I’m slowly adding more as I get more comfortable with ANTLR.

If you’re using connection strings with an executable, set Application Name to the executable name. If you have to use SQL Profiler to diagnose performance issues, it will be easier to filter out a specific application or web site.

<connectionStrings>
  <add name="LocalSqlServer" connectionString="... Application Name=mywebsite.com;" />
  <add name="LocalSqlServer" connectionString="... Application Name=myapp.exe" />
</connectionStrings>

I was writing a custom config section, and trying to figure out why this wasn’t throwing a duplicate key error:

<monitors>
  <monitor name="File" />
  <monitor name="File" />
</monitors>

After surfing Google endlessly, I finally found this on MSDN:

Note that elements with identical keys and values are not considered duplicates, and are accepted silently. Only elements with identical keys but different values are considered duplicates.

That was fun. :-/
