---
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.
