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

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!
