1.首先备份当前安装visualSVN文件的bin目录,万一出错还能反个水。一般默认安装路径是C:\Program Files (x86)\VisualSVN\bin

2.然后运行ildasm,Window中有自带的反编译ildasm工具,位于“C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\”。

3.用ildasm打开刚才备份的bin目录下的VisualSVN.Core.L.dll文件,单击文件菜单点击转储,如图

4.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3188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_005e:ldloc.2
IL_005f: ret
} // end of method LicenseConverter::KeyToLicenseUnsafe

5.用管理员权限打开VS命令提示工具,如下图↓,我装的是VS2015

6. 运行下面的代码

,看到successfully表示成功了。将重新编译的dll文件覆盖到安装目录中就OK了。

7.然后运行你的VS就可以看到VisualSVN---About已经没有Lisence时间限制啦!
