    对于Visual Studio开发人员来说，Visual SourceSafe可能是一套最常见的版本控制工具，它与Visual Studio的无缝绑定，使用户倍感亲切和方便。但如果你向无SourceSafe环境中迁移或共享源代码，或者改变其他版本控制工具（如CVS、Subversion）时，可能会遇到麻烦。

    因为Visual SourceSafe是通过大量修改项目信息，来实现版本信息的标识和管理。不仅在项目目录中加入新的控制文件；同时他还修改项目方案文件，加入相关XML元素。尽管所有这些改变对用户来说都是透明的，但要去除VSS绑定还并非易事，关键在与一下几个步骤：

    1、关闭Visual Studio IDE环境  

    在Visual Studio IDE 运行过程中，由于共享冲突，这下面步骤是无法操作的，因此首先要关闭IDE环境。

    2、去除方案文件中的版本信息

    在Visual Studio 2003环境下，方案文件是后缀为.Sln的文本文件。用记事本打开，在其中找到Global块下的GlobalSection
    (SourceCodeControl)，代码如下
    Microsoft Visual Studio Solution File, Format Version 8.00

    Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") =

    "项目名称",

    "项目名称\项目名称.csproj",

    "{C7687560-4B36-47E3-AF33-748E76411259}"

        ProjectSection(ProjectDependencies) = postProject

        EndProjectSection

    EndProject

    Global  

      GlobalSection(SourceCodeControl) = preSolution

            SccNumberOfProjects = 2

            SccLocalPath0 = .

            CanCheckoutShared = false

            SolutionUniqueID = {634C866F-3CEB-43A1-9C7F-D34A03F0A044}

            SccProjectUniqueName1 =

            项目名称\\项目名称.csproj

            SccLocalPath1 = .

            CanCheckoutShared = false

            SccProjectFilePathRelativizedFromConnection1 =

                项目名称\\

        EndGlobalSection

        GlobalSection(SolutionConfiguration) = preSolution

      GlobalSection(SourceCodeControl) = preSolution

            SccNumberOfProjects = 2

            SccLocalPath0 = .

            CanCheckoutShared = false

            SolutionUniqueID = {634C866F-3CEB-43A1-9C7F-D34A03F0A044}

            SccProjectUniqueName1 =

            项目名称\\项目名称.csproj

            SccLocalPath1 = .

            CanCheckoutShared = false

            SccProjectFilePathRelativizedFromConnection1 =

                项目名称\\

        EndGlobalSection

        GlobalSection(SolutionConfiguration) = preSolution

            Debug = Debug

            Release = Release

        EndGlobalSection

        GlobalSection(ProjectConfiguration) = postSolution

         {C7687560-4B36-47E3-AF33-748E76411259}.Debug.ActiveCfg

            = Debug|.NET

         {C7687560-4B36-47E3-AF33-748E76411259}.Debug.Build.0

            = Debug|.NET

         {C7687560-4B36-47E3-AF33-748E76411259}.Release.ActiveCfg

            = Release|.NET

         {C7687560-4B36-47E3-AF33-748E76411259}.Release.Build.0

            = Release|.NET

        EndGlobalSection

        GlobalSection(ExtensibilityGlobals) = postSolution

        EndGlobalSection

        GlobalSection(ExtensibilityAddIns) = postSolution

        EndGlobalSection

    EndGlobal

    其中GlobalSection(SourceCodeControl)块包含着VSS绑定信息，删除该块并保存。

    3、去除项目文件中的版本信息  

    用记事本打开对应项目，在其中找到XML tag <CSHARP>，删除SccProjectName、SccLocalPath、SccAuxPath、SccProvider。代码如下
    <VisualStudioProject>

        <CSHARP

            ProjectType = "Local"

            ProductVersion = "7.10.3077"

            SchemaVersion = "2.0"

            ProjectGuid = "{C7687560-4B36-47E3-AF33-748E76411259}"       

            SccProjectName = "SAK"

            SccLocalPath = "SAK"

            SccAuxPath = "SAK"

            SccProvider = "SAK"

            SccProjectName = "SAK"

            SccLocalPath = "SAK"

            SccAuxPath = "SAK"

            SccProvider = "SAK"

        >

            <Build>

                <Settings

                ApplicationIcon = "App.ico"
   
                AssemblyKeyContainerName = ""

                AssemblyName = "SourceSafeBindingRemover"

                AssemblyOriginatorKeyFile = ""

                DefaultClientScript = "JScript"

                DefaultHTMLPageLayout = "Grid"

                DefaultTargetSchema = "IE50"

                DelaySign = "false"

                OutputType = "WinExe"

                PreBuildEvent = ""

                PostBuildEvent = ""

                RootNamespace = "SourceSafeBindingRemover"

                RunPostBuildEvent = "OnBuildSuccess"

                StartupObject = ""

            >

                <Config

                    Name = "Debug"

                    AllowUnsafeBlocks = "false"

                    BaseAddress = "285212672"

                    CheckForOverflowUnderflow = "false"

                    ConfigurationOverrideFile = ""

                    DefineConstants = "DEBUG;TRACE"

                    DocumentationFile = ""

                    DebugSymbols = "true"

                    FileAlignment = "4096"

                    IncrementalBuild = "false"

                    NoStdLib = "false"

                    NoWarn = ""

                    Optimize = "false"

                    OutputPath = "bin\Debug\"

                    RegisterForComInterop = "false"

                    RemoveIntegerChecks = "false"

                    TreatWarningsAsErrors = "false"

                    WarningLevel = "4"

                />

    ... sections deleted

        </CSHARP>

    </VisualStudioProject>

    注意：如果这是一个VB项目，对应的Tag应该是 <VisualBasic>。

    在Visual Studio 2005中，项目信息变化较大（它基于MSBuild），但要删除的内容却是显而易见的，如下
    <PropertyGroup>

        <Configuration Condition=" '$(Configuration)' =  = '' ">Debug</Configuration>

        <Platform Condition=" '$(Platform)' =  = '' ">AnyCPU</Platform>

        <ProductVersion>8.0.40903</ProductVersion>

        <SchemaVersion>2.0</SchemaVersion>

        <ProjectGuid>{951EBC65-CA21-4C24-B501-DFF2A03A03F1}</ProjectGuid>

        <OutputType>Library</OutputType>

        <StartupObject>

        </StartupObject>

        <AssemblyName>SourceSafeBindingRemover</AssemblyName>

        <RootNamespace>SourceSafeBindingRemover</RootNamespace>  

        <SccProjectName>SAK</SccProjectName>

        <SccLocalPath>SAK</SccLocalPath>

        <SccAuxPath>SAK</SccAuxPath>

        <SccProvider>SAK</SccProvider>

      </PropertyGroup>

    4、删除所有后缀为.SCC的文件。
   
    最后一步信息，就是删除项目目录下所有后缀为.SCC的文件。
  
    其中每一目录下，都包含有文件vssver.scc
  
    项目文件所在目录下，包含有文件mssccprj.scc
  
    另外，还包括<Project Name>.csproj.vspscc 或 <Solution Name>.etp.vspscc文件
