# Transforming .NET applications with Amazon Q Developer
<a name="transform-dotnet-IDE"></a>

Amazon Q Developer can port your Windows-based .NET applications to Linux-compatible cross-platform .NET applications through a generative AI-powered refactoring workflow. Amazon Q also helps you upgrade outdated versions of cross-platform .NET applications to newer versions. 

To transform a .NET solution or project, Amazon Q analyzes your codebase, determines the necessary updates to port your application, and generates a transformation plan before the transformation begins. During this analysis, Amazon Q divides your .NET solution or project into code groups that you can view in the transformation plan. A *code group* is a project and all its dependencies that together generate a buildable unit of code such as a dynamic link library (DLL) or an executable. 

During the transformation, Amazon Q provides step-by-step updates in a Transformation Hub where you can monitor progress. After transforming your application, Amazon Q generates a summary with the proposed changes in a diff view for you to optionally verify the changes before you accept them. When you accept the changes, Amazon Q makes in-place updates to your .NET solution or project. 

Amazon Q performs four keys tasks to port .NET applications to Linux:
+ **Upgrades language version** – Replaces outdated C\# versions of code with Linux-compatible C\# versions.
+ **Migrates from .NET Framework to cross-platform .NET** – Migrates projects and packages from Windows dependent .NET Framework to cross-platform .NET compatible with Linux.
+ **Rewrites code for Linux compatibility** – Refactors and rewrites deprecated and inefficient code components.
+ **Generates a Linux compatibility readiness report **– For open-ended tasks where user intervention is needed to make the code build and run on Linux, Amazon Q provides a detailed report of actions needed to configure your application after transformation.

## Quotas
<a name="quotas-dotnet-transformation"></a>

.NET transformations with Amazon Q in the IDE maintain the following quotas: 
+ **Lines of code per job** – The maximum number of code lines that Amazon Q can transform in a given transformation job. This is also the monthly total limit for .NET transformations. 
+ **Concurrent jobs** – The maximum number of transformation jobs you can run at the same time. This quota applies to all transformations in the IDE, including [Java transformations](transform-java.md).


| Resource | Quotas | 
| --- | --- | 
| Lines of code per job | 100,000 lines of code | 
| Concurrent jobs | 1 job per user<br />2 jobs per AWS account |
