+# MA0155 - UseShellExecute must be explicitly set
+
+Detects when `Process.Start` is called without specifying the value of `UseShellExecute`.
+
+The goal is to help for those two cases:
+- The default value for this property is true on .NET Framework apps and false on .NET Core apps. 
+- It must be set to to false when redirecting I/O.
+
+
+````c#

+Process.Start("cmd"); // Intent is not clear if you want to use ShellExecute or not

+
+Process.Start(new ProcessStartInfo("cmd")
+{
+    RedirectStandardOutput = true,
+    UseShellExecute = true,
+});  // It will throw with error "UseShellExecute must be set to false when redirecting I/O"
