+#### .Net Test
+
+The [JunitXML.TestLogger](https://www.nuget.org/packages/JunitXml.TestLogger/) nuget
+package can generate test reports for .Net Framework and .Net Core applications. The following
+example expects a solution in the root folder of the repository, with one or more 
+project files in sub-folders. One result file is produced per test project, and each
+are placed in a new artifacts folder. This example includes optional formatting arguments, which
+improve the readability of test data in the test widget. A full .Net Core example is availble 
+[here](https://gitlab.com/Siphonophora/dot-net-cicd-test-logging-demo).
+
+```yaml
+## Source code and documentation are here: https://github.com/spekt/junit.testlogger/
+
+Test:
+  stage: test
+  script: 
+    - 'dotnet test --test-adapter-path:. --logger:"junit;LogFilePath=..\artifacts\{assembly}-test-result.xml;MethodFormat=Class;FailureBodyFormat=Verbose"'
+  artifacts:
+    when: always
+    paths: 
+     - .\**\*test-result.xml
+    reports:

+       - .\**\*test-result.xml
+```

 ## Limitations
 
 Currently, the following tools might not work because their XML formats are unsupported in GitLab.
