Need to append the assembly entry in web.config file while installing NuGet

Question

Hi,
Consider that I need to create three NuGets. Second and third are dependents for first one. Each one has its own web.config file, which file content is same except one tag's value. While I'm installing the first NuGet, it will install the second and third too
which is fine. The NuGets are installing one by one. But the issue is while I'm installing the NuGet in an ASP.NET project, the web.cofig file gets replace with one another that means the last NuGet's web.config file is only remains at last. But I need to
append that tag value one by one. Is there any possibilities to create NuGets in that way? Please help me as soon as possible. Thanks in advance.
I need this...
<assemblies>
<add assembly="Abc.EM, Version=10.0.0.1, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" />
<add assembly="Def.EM, Version=10.0.0.1, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" />
<add assembly="Ghi.EM, Version=10.0.0.1, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" />
</assemblies>
But I got this...
<assemblies>
<add assembly="Ghi.EM, Version=10.0.0.1, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" />
</assemblies>

Hi mathikp,
One solution is to use the DTE object model to find the ASP.NET project, enumerate all the project items in the project to find the Web.config file. Then change the content by your self. This will be done after you install the Nuget package in the project.
