+To programmatically configure a file outside the classpath:
+```java
+public static void main(String[] args) {
+    System.setProperty("applicationinsights.configuration.file", "{path}/applicationinsights-dev.json");
+    ApplicationInsights.attach();

+}
+```
+
+#### Programmatically configure the connection string
+
+First, add the `applicationinsights-core` dependency:
+
+```xml
+<dependency>
+    <groupId>com.microsoft.azure</groupId>
+    <artifactId>applicationinsights-core</artifactId>
+    <version>3.4.19</version>
+</dependency>
+```
+
+Then, call the `ConnectionString.configure` method after `ApplicationInsights.attach()`:
+
+```java
+public static void main(String[] args) {
+    System.setProperty("applicationinsights.configuration.file", "{path}/applicationinsights-dev.json");
+    ApplicationInsights.attach();
+    SpringApplication.run(PetClinicApplication.class, args);
+}
+```
+Alternatively, call the  `ConnectionString.configure` method from a Spring component.
+
+Enable connection string configured at runtime:
 
 ```json
 {
-  "connectionString":"Your-Intrumentation-Key"
+  "connectionStringConfiguredAtRuntime": true
 }
 ```
