使用Updater Application Block 2.0-.NET心得介绍

1,在Updater Application Blocek2.0中有7个项目文件需要添加：

Microsoft.ApplicationBlocks.Updater.dll
Microsoft.ApplicationBlocks.Updater.Downloaders.dll
以上两个需在项目中引用
Microsoft.ApplicationBlocks.Updater.ActivationProcessors.dll
Microsoft.Practices.EnterpriseLibrary.Security.Cryptography.dll
Microsoft.Practices.EnterpriseLibrary.Common.dll
Microsoft.Practices.EnterpriseLibrary.Logging.dll
Microsoft.Practices.ObjectBuilder.dll
以上七个文件都需复制到项目输出目录内

2,App.config文件应添加到项目中,系统会自动在项目输出目录内生成和其内容一样的,"应用程序名.exe.config",文件

附本人的App.config
<configuration>
<configSections>
<section name="UpdaterConfiguration" type="Microsoft.ApplicationBlocks.Updater.Configuration.ApplicationUpdaterSettings, Microsoft.ApplicationBlocks.Updater" />
<section name="securityCryptographyConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Security.Cryptography.Configuration.CryptographySettings, Microsoft.Practices.EnterpriseLibrary.Security.Cryptography, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null" />
</configSections>
<UpdaterConfiguration defaultDownloader="BITS" applicationId="{F03514FA-970B-430C-9F3B-54579267B364}" manifestUri="http://219.155.XX.XX/update/manifests.xml">
<downloaders>
<add name="BITS" type="Microsoft.ApplicationBlocks.Updater.Downloaders.BitsDownloader, Microsoft.ApplicationBlocks.Updater.Downloaders"
authenticationScheme="BG_AUTH_SCHEME_NTLM"
targetServerType="BG_AUTH_TARGET_SERVER" />
</downloaders>
</UpdaterConfiguration>
<securityCryptographyConfiguration>
<hashProviders>
<add algorithmType="System.Security.Cryptography.MD5CryptoServiceProvider, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
saltEnabled="true" type="Microsoft.Practices.EnterpriseLibrary.Security.Cryptography.HashAlgorithmProvider, Microsoft.Practices.EnterpriseLibrary.Security.Cryptography, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null"
name="MD5CryptoServiceProvider" />
</hashProviders>
</securityCryptographyConfiguration>
</configuration>

applicationId为唯一标识,如和manifests.xml的不一样,则程序不会进行更新
manifestUri为远程manifests.xml文件的地址

3,程序是否更新取决于manifests.xml文件的manifestID是否更改,如更改则更新

附本人的manifests.xml文件
<manifest manifestId="{C6F5852B-B331-42D3-9AAC-87A45F961BE1}" mandatory="False"
xmlns="urn:schemas-microsoft-com:PAG:updater-application-block:v2:manifest">
<description>a description for this manifest</description>
<application applicationId="{F03514FA-970B-430C-9F3B-54579267B364}">
<entryPoint file="Express.exe" parameters="" />
<location>.</location>
</application>
<files base="http://219.155.XX.XX/update">
<file source="Express.exe" />
</files>
<activation>
<tasks>
<task name="WaitForApplicationExitProcessor" type="Microsoft.ApplicationBlocks.Updater.ActivationProcessors.WaitForApplicationExitProcessor, Microsoft.ApplicationBlocks.Updater.ActivationProcessors"/>
<task name="ApplicationDeployProcessor" type="Microsoft.ApplicationBlocks.Updater.ActivationProcessors.ApplicationDeployProcessor, Microsoft.ApplicationBlocks.Updater.ActivationProcessors"/>
</tasks>
</activation>
</manifest>

updater Application Blocek本身下载速度较慢,有网友已写出HTTP下载程式,速度比较快.
