Returns the type of a directive processor, given its friendly name.
Assembly: Microsoft.VisualStudio.TextTemplating.Interfaces.10.0 (in Microsoft.VisualStudio.TextTemplating.Interfaces.10.0.dll)
The engine calls this method based on the directives the user has specified in the text template. This method can be called 0, 1, or multiple times, for each text template transformation. For more information, see T4 Text Template Directives.
If the directive processor name cannot be resolved, this method should throw an exception.
If the mechanism that the host uses to find a directive processor in the method is not secure, a malicious directive processor could be run. The malicious directive processor could provide code that is run in full trust mode when the template is run. If you create a custom host, you must use a secure mechanism, such as the registry, to locate directive processors. For more information, see Security of Text Templates.
The following code example shows a possible implementation for a custom host. This code example is part of a larger example that is provided for the ITextTemplatingEngineHost interface.
For a more detailed example that shows how to resolve a request for a generated directive processor, see Walkthrough: Connecting a Host to a Generated Directive Processor.
