How to Resolve FileNotFoundException for XmlSerializer by Enabling Automatic Serialization Assembly Generation?

Resolving FileNotFoundException for XmlSerializer by Enabling Automatic Assembly Generation

Encountering a FileNotFoundException when using XmlSerializer is often due to a missing serialization assembly. While the framework can automatically generate this, it requires specific configuration.

Enabling Automatic Serialization Assembly Generation

Visual Studio's "Generate Serialization Assembly" project property (set to "On") is a crucial first step. However, this alone may be insufficient because of the /proxytypes flag used by sgen.exe during the build.

Disabling Proxy Type Generation

Microsoft's MSBuild property SGenUseProxyTypes provides a solution. Setting this to false prevents proxy type generation, enabling serialization assembly creation even for non-webservice types.

Manually Editing the Project File (.csproj)

Since Visual Studio lacks a direct interface for SGenUseProxyTypes, manual modification of your .csproj file is necessary. Add the following within the relevant <propertygroup></propertygroup> for your build configuration:

<sgenuseproxytypes>false</sgenuseproxytypes>

Example Modified Project File <propertygroup></propertygroup>:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x86' ">
  <GenerateSerializationAssemblies>On</GenerateSerializationAssemblies>
  <SGenUseProxyTypes>false</SGenUseProxyTypes>
</PropertyGroup>

By disabling the /proxytypes switch this way, the project will correctly generate the needed XmlSerializer assembly during the build, eliminating the FileNotFoundException and ensuring smooth application execution.
