Programming, error messages and sample code > sample code
By default, ASP.NET Core request time out is 2 minutes, and we can change it via requestTimeout in setting file. For more ASP.NET Core configuration, please refer to ASP.NET Core Module configuration reference

      <aspNetCore processPath="dotnet" arguments=".\MyApp.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" requestTimeout="00:20:00">
Note: For apps running on .NET Core 2.2 or later, the ASP.NET Core Module supports an in-process hosting model. The requestTimeout attribute doesn't apply to in-process hosting.
