这里就使用了License, LicenseProvider, RegistryFileLicenseProvider。直接删除
public virtual bool IsLicensed()
{
if (this.License != null)
{
return true;
}
try
{
this.License = LicenseManager.Validate(base.GetType(), this);
return true;
}
catch
{
return false;
}
}
使他返回TRUE；

换成：
.method public hidebysig newslot virtual instance bool IsLicensed() cil managed
{
.maxstack 1
.locals init (
[0] bool CS$1$0000)

2. 删除VS2005对项目的权限检查。
一般就是依赖了LicenseProviderAttribute，打开IL，找到类似的代码，直接删除。20 多个！
.custom instance void [System]System.ComponentModel.LicenseProviderAttribute::.ctor(class
[mscorlib]System.Type) = ( 01 00 3C 43 6F 6D 70 6F 6E 65 6E 74 41 72 74 2E // ..<ComponentArt.
