+# 0027 Specifying Environment Variables In RunSettings File
+
+## Summary
+Specifying environment variables in the runsettings file. The environment variables can be set which can directly interact with the test host.
+
+## Motivation
+Specifying environment variables in the runsettings file is necessary to support non-trivial projects that require settings env vars like DOTNET_ROOT. These variables are set while spawning the test host process, thus will be available in the host.
+
+## Usage
+The runsettings contains a "EnvironmentVariables" node in the RunConfiguration section.
+The different environment variables can be specified as element name and it's value.
+Below is a sample runsettings for passing environment variables.
+
+```csharp
+
+<?xml version="1.0" encoding="utf-8"?>
+<!-- File name extension must be .runsettings -->
+<RunSettings>
+  <RunConfiguration>
+    <EnvironmentVariables>
+      <!-- List of environment variables we want to set as element and its value-->
+      <DOTNET_ROOT>C:\ProgramFiles\dotnet</DOTNET_ROOT>
+      <SDK_PATH>C:\Codebase\Sdk</SDK_PATH>
+    </EnvironmentVariables>
+  </RunConfiguration>
+</RunSettings>
+
+
+```
+Since these environment variables should always be set when the test host is started, the tests should always run in a separate process.
+For this, the `/InIsolation` flag will be set when there are environment variables so that the test host is always invoked.
