+### Using client SDK in [Azure Functions][azure-functions]
+Azure Function doesn't currently support [bindingRedirect][binding-redirect] **element**
+
+**Example**
+
+```
+<dependentAssembly>
+        <assemblyIdentity name="Validation" publicKeyToken="2fc06f0d701809a7" culture="neutral" />
+        <bindingRedirect oldVersion="0.0.0.0-2.2.0.0" newVersion="2.2.0.0" />
+</dependentAssembly>
+```
+
+So **workaround** would be to directly install older version of **validation.dll** using [project.json][project-json] covered under [Package management][package-management] 
+
+**Example**
+
+```
+{
+"frameworks": {
+    "net46":{
+        "dependencies": {
+            "Microsoft.Azure.Devices.Client": "1.1.1",
+             "Validation": "2.0.6.15003"
+                    }
+                }
+        }
+}
