+function Invoke-DotNetReleaseBuild {
+    <#
+    .SYNOPSIS
+    Builds a .NET project in Release configuration and prepares release artefacts.
+
+    .DESCRIPTION
+    Wrapper around the build, pack and signing process typically used for publishing
+    .NET projects. The function cleans the Release directory, builds the project,
+    signs DLLs and NuGet packages when a certificate is provided, compresses the
+    build output and returns details about the generated files.
+
+    .PARAMETER ProjectPath
+    Path to the folder containing the project (*.csproj) file.
+
+    .PARAMETER CertificateThumbprint
+    Optional certificate thumbprint used to sign the built assemblies and NuGet
+    packages. When omitted no signing is performed.
+
+    .PARAMETER LocalStore
+    Certificate store used when searching for the signing certificate. Defaults
+    to 'CurrentUser'.
+
+    .PARAMETER TimeStampServer
+    Timestamp server URL used while signing.
+
+    .OUTPUTS
+    PSCustomObject with properties Version, ReleasePath and ZipPath.
+
+    .EXAMPLE
+    Invoke-DotNetReleaseBuild -ProjectPath 'C:\Git\MyProject' -CertificateThumbprint '483292C9E317AA13B07BB7A96AE9D1A5ED9E7703'
+    Builds and signs the project located in C:\Git\MyProject and returns paths to
+    the release output.
