.NET Compatibility

The table below shows which .NET version each major Dynamo release series targets. This is relevant when building packages or extensions, as your project must target a compatible .NET version.

Dynamo Version	.NET Version
0.9 – 2.0	.NET Framework 4.5
2.1 – 2.6	.NET Framework 4.7
2.7 – 2.19	.NET Framework 4.8
3.0 – 3.6	.NET 8
3.3.2	.NET 10
3.7	.NET 10
4.0+	.NET 10

3.3.2 and 3.7 are special releases with .NET 10 backported from the 4.0 release candidate.

For guidance on updating your packages to a new .NET version, see the migration guides in the Developer Primer:

• Updating Packages for Dynamo 2.x

• Updating Packages for Dynamo 3.x / .NET 8

• Updating Packages for Dynamo 4.x / .NET 10
