VisualSVN 破解方法

第一步，首先准备反汇编工具 ildasm.exe,找到VisualSVN的安装路径，一般先备份，在备份里面操作。

第二步，转储，得到同名的il文件：VisualSVN.Core.L.il，用记事本打开得到的 VisualSVN.Core.L.il 文件，在其中搜索 “KeyToLicenseUnsafe”，找到KeyToLicenseUnsafe方法，大概在3296行附近。查找并替换成下面的代码，然后保存

.method public hidebysig static class VisualSVN.Core.Licensing.License
          KeyToLicenseUnsafe(class VisualSVN.Core.IDecoder decoder,
                             string key) cil managed
  {
    // 代码大小       69 (0x45)
    .locals init (class VisualSVN.Core.Licensing.License V_0, class VisualSVN.Core.Licensing.License V_1, class VisualSVN.Core.Licensing.License V_2)
    IL_0000: nop
    IL_0001: newobj instance void VisualSVN.Core.Licensing.License::.ctor()
    IL_0006: stloc.1
    IL_0007: ldloc.1
    IL_0008: ldsfld valuetype [mscorlib]System.DateTime [mscorlib]System.DateTime::MinValue
    IL_000d: stfld valuetype [mscorlib]System.DateTime VisualSVN.Core.Licensing.License::StartTime
    IL_0012: ldloc.1
    IL_0013: ldc.i4.1
    IL_0014: stfld valuetype VisualSVN.Core.Licensing.LicenseBinding VisualSVN.Core.Licensing.License::Binding
    IL_0019: ldloc.1
    IL_001a: ldc.i4 0x7ffffffe
    IL_001f: stfld int32 VisualSVN.Core.Licensing.License::Capacity
    IL_0024: ldloc.1
    IL_0025: ldsfld valuetype [mscorlib]System.DateTime [mscorlib]System.DateTime::MaxValue
    IL_002a: stfld valuetype [mscorlib]System.DateTime VisualSVN.Core.Licensing.License::EndTime
    IL_002f: ldloc.1
    IL_0030: ldc.i4.2
    IL_0031: stfld valuetype VisualSVN.Core.Licensing.LicenseType VisualSVN.Core.Licensing.License::Type
    IL_0036: ldloc.1
    IL_0037: ldstr "100"
    IL_003c: stfld string VisualSVN.Core.Licensing.License::PurchaseId
    IL_0041: ldloc.1
    IL_0042: call string [mscorlib]System.Environment::get_UserName()
    IL_0047: stfld string VisualSVN.Core.Licensing.License::LicensedTo
    IL_004c: ldloc.1
    IL_004d: stloc.0
    IL_004e: ldloc.0
    IL_004f: ldloc.0
    IL_0050: ldfld valuetype [mscorlib]System.DateTime VisualSVN.Core.Licensing.License::StartTime
    IL_0055: stfld valuetype [mscorlib]System.DateTime VisualSVN.Core.Licensing.License::PurchaseDate
    IL_005a: ldloc.0
    IL_005b: stloc.2
    IL_005c: br.s
    IL_005e
    IL_005e:ldloc.2
    IL_005f: ret
  } // end of method LicenseConverter::KeyToLicenseUnsafe

第三步，用vs2015开发人员命令提示，然后覆盖到 bin目录

用vs2015开发人员命令提示运行如下代码（换成自己的）

ilasm "C:\Program Files (x86)\VisualSVN\bins\VisualSVN.Core.L.il" /output="C:\Program Files (x86)\VisualSVN\bins\VisualSVN.Core.L.dll" /dll

看到如下界面

表示编译成功，然后把编译好的VisualSVN.Core.L.dll 覆盖到 bin目录下就完成破解了。

VS2017 破解如下

当你的vs2017报出“All functions of VisualSVN are disabled because your evaluation period is expired.
You can purchase VisualSVN license at http://www.visualsvn.com/visualsvn/purchase/”时，说明你的VisualSVN过期了
直接上关键：

1.在vs上卸载VisualSVN，打开vs 2017 ，点击‘工具’，选择‘扩展和更新’

2. 搜索'svn' 会出现下图所示，找到VisualSvn for Visual Studio 2017 ，点击卸载，然后关闭vs就完事了，他们自己卸载

3.双击运行VS2017_VisualSVN_破解版.vsix，傻瓜式安装。下载地址：https://download.csdn.net/download/atgeretg/11212079

4.打开C:\Users\dg21904380\AppData\Local\Microsoft\VisualStudio\15.0_7de71202\Extensions，然后搜索“VisualSVN.Core.L.dll”，找到他，替换即完成永久破解。这个“15.0_7de71202”文件夹不一是叫这个名，自己看着办。
