# Example applications for .NET

The `/samples/cs` directory contains four sample applications written in C#, designed to illustrate use of the Saxon API available in the `Saxon.Api` namespace. These are:

- XsltExamples, which shows a variety of ways of invoking XSLT transformations from C#

- XQueryExamples, which similary shows different ways of running XQuery

- XPathExample, a simple application using XPath to find words within a data file such as `othello.xml`

- SchemaExample, which shows how to compile and verify a schema, and use it to validate an instance document and generate a typed document instance in the XDM data model.

The main value of these samples is in reading the source code rather than in actually running them; however, running them is also a good check that your installation has been set up correctly. a quick look at the comments in the source should enable you to see how they are executed. Note that they all require the environment variable `SAXON_HOME` to be set to the directory where Saxon is installed: this is used to find the sample data files.
