How to Use .gitignore in D365 F&O (Complete Guide for Developers)

If your repository is cluttered with unnecessary files, slow check-ins, and confusing changes, your .gitignore likely needs attention—especially in enterprise ERP development. In Dynamics 365 Finance and Operations, managing source control properly isn’t optional; it directly impacts build reliability, collaboration, and deployment efficiency.

This guide walks you through how to use .gitignore effectively in D365 F&O projects—and includes a ready-to-use sample you can download and apply immediately.


🚀 Why .gitignore matters in D365 F&O

Development in D365 F&O using Visual Studio produces a large number of temporary, generated, and environment-specific files.

If these files are committed into Git:

  • Your repository size grows unnecessarily
  • Developers face constant merge conflicts
  • Builds become inconsistent across environments

.gitignore ensures only relevant, reproducible source files are tracked.


📂 What should NOT go into source control

1) Build outputs & binaries

These are generated during compilation and should never be committed:

**/bin/
**/obj/
**/*.dll
**/*.pdb

2) Visual Studio user-specific files

These vary by developer machine:

*.suo
*.user
*.userosscache
*.sln.docstates
.vs/

3) D365 F&O generated artifacts

System-generated metadata and temp files:

**/xppMetadata/Temp/
**/xppMetadata/Generated/
**/xppSource/Temp/
