+## Using msbuild props with File-Based C# Application
+
+Single file csharp applications can also be used with msbuild props files. You can create a `*.props` file and the dotnet sdk will automatically include it when running the file-based application.
+
+1. Create a file named `Directory.build.props` with the following content:
+
+    ```xml
+    <Project>
+        <ItemGroup>
+        <PackageReference Include="TUnit" Version="*" />
+        </ItemGroup>
+    </Project>
+    ```
+
+2. Create a csharp file with the following content:
+
+    ```csharp
+    using TUnit;
+    public class Tests
+    {
+        [Test]
+        public void Basic()
+        {
+            Console.WriteLine("This is a basic test");
+        }
+
+        [Test]
+        [Arguments(1, 2, 3)]
+        [Arguments(2, 3, 5)]
+        public async Task DataDrivenArguments(int a, int b, int c)
+        {
+            Console.WriteLine("This one can accept arguments from an attribute");
+            var result = a + b;
+            await Assert.That(result).IsEqualTo(c);
+        }
+    }
+    ```
+
+3. Run the script using the following command:
+
+    ```powershell
+    dotnet run file.cs
+    ```
+
+This will automatically include the `Directory.build.props` file as long as it is in the same directory as the csharp file, and you will be able to run your tests with TUnit.
