(Don't include 183 | the brackets!) The text should be enclosed in the appropriate 184 | comment syntax for the file format.

To enable resolution of controllers from Unity you need to add following line to MVC configuration: 57 | 58 | ```C# 59 | public void ConfigureServices(IServiceCollection services) 60 | { 61 | ... 62 | services.AddMvc() 63 | .AddControllersAsServices() //<-- Add this line 64 | .SetCompatibilityVersion(CompatibilityVersion.Version_3_0) 65 | ... 66 | } 67 | ``` 68 | 69 | ## Examples 70 | 71 | For example of using Unity with Core 3.1 Web application follow [this link](https://github.com/unitycontainer/examples/tree/master/src/web/ASP.Net.Unity.Example) 72 | 73 | ## Code of Conduct 74 | 75 | This project has adopted the code of conduct defined by the [Contributor Covenant](https://www.contributor-covenant.org/) to clarify expected behavior in our community.
