Third Party View Engines R.I.P?

After finishing my recent overview of ASP.NET MVC view engines, I thought that I would take a deeper look at a specific third party view engine implementation. The users of Stack Overflow have provided a good list of available view engines. I took a brief look at the web sites for all of the view engines, and one thing that really stuck out at me was the fact that none of them had been updated for quite some time.

Despite this, I decided that I would experiment one of them, and chose NHaml. Based on the Rails Haml view engine, NHaml sounds intriguing to me. It takes a different approach than most by abstracting away the HTML markup language.

I saw that a NuGet package was available for NHaml, so i figured that chances for getting it running were promising. Unfortunately, after fiddling around with it for a while, I did not have good luck getting it running under MVC5. I managed to get around the initial error with the NuGet package (Derived types must either match the security accessibility of the base type or be less accessible) by downloading the source code and removing the “AllowPartiallyTrustedCallers” attribute from the SharedAssemblyInfo.cs in the System.Web.NHaml project. However, I then found myself running into access denied errors as NHaml apparently tries to delete temp files from disk.

Considering that NHaml has not been updated for quite some time, I decided that it wasn’t worth investing anymore time into getting it up and running. I may still take a look at one of the other view engines, just to get a sense for how different it is from Razor.

I do still wonder why there has been no recent action on the third party view engine front. I don’t have any complaints about Razor, but is it really that good that it deserves no well maintained competition other than the ASPX view engine? Apparently, Microsoft has done a good job of meeting the desires of developers with the feature set that they have provided in Razor.
