title: "Write Assembly Versions"
---
Updates AssemblyVersion, AssemblyFileVersion, and AssemblyInformationalVersion Attributes (in AssemblyInfo source files).
DotNet::Write-AssemblyVersion(
	[AssemblyVersion: <text>],
	[FileVersion: <text>],
	[InformationalVersion: <text>],
	[FromDirectory: <text>],
	[Include: <@(text)>],
	[Exclude: <@(text)>]
);
| Name | Format | Script Usage | Usage Notes | 
|---|---|---|---|
| Assembly version | text | AssemblyVersion | Default value is "$ReleaseNumber.$PackageNumber". | 
| File version | text | FileVersion | Value note: "same as AssemblyVersion". | 
| Informational version | text | InformationalVersion | Value note: "same as AssemblyVersion". | 
| From directory | text | FromDirectory | Value note: "$WorkingDirectory". | 
| Include | @(text) | Include | See KB#1119 to learn more about masking syntax. Default value is "**\AssemblyInfo.cs". | 
| Exclude | @(text) | Exclude | 
Note: This operation is intended to be used when assembly version attributes are stored directly in AssemblyInfo.cs. To set these values in the project file instead, use DotNet::SetProjectVersion.
