Register any version of assembly in ASP .NET page

asp.net assemblies version

Solution 1

Just drop the Version= portion:

<%@ Register Assembly="CrystalDecisions.Web, , Culture=neutral, 
                       PublicKeyToken=692fbea5521e1304"
             Namespace="CrystalDecisions.Web" 
             TagPrefix="CR" %>

However this only works with late binding. If you actually compile any of your assemblies against a specific version of the assembly you will need an assembly binding redirect in your Web.config file.

<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="CrystalDecisions.Web"
                  publicKeyToken="692fbea5521e1304"
                  />

        <bindingRedirect oldVersion="10.5.3700.0"
                 newVersion="13.0.2000.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

Solution 2

You need to use the assemblyBinding section in your web.config file. See this article.

Solution 3

You could just do this:

<%@ Register Assembly="CrystalDecisions.Web, Culture=neutral,
PublicKeyToken=692fbea5521e1304"
Namespace="CrystalDecisions.Web" TagPrefix="CR" %>

This will allow you load any version.

How can I use any available version of an assembly on an ASP .NET page?

For example, I use this tag before adding a Crystal Reports control on a web page on my computer:
```
<%@ Register Assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"
Namespace="CrystalDecisions.Web" TagPrefix="CR" %>
```
However, if I install this web page on a computer that has a different version of Crystal Reports, I would have to change the version part of the assembly attribute:
```
<%@ Register Assembly="CrystalDecisions.Web, Version=10.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"
Namespace="CrystalDecisions.Web" TagPrefix="CR" %>
```
Is there any way I can avoid this by instructing ASP .NET to use the newest available version or specify the minimum required version?

I tried that but got an error: Could not load file or assembly 'CrystalDecisions.Web, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies. The system cannot find the file specified

The error is accurate - you're probably missing one of the dependencies of the specific version that was loaded. This is one of the dangers of ignoring the version.

I have three versions of the assembly in my GAC. They all work fine when I specify a version -- I tried with each version. But it fails without the version= portion. According to Process Monitor, w3wp searches for CrystalDecisions.Web.dll and CrystalDecisions.Web.exe only in the /bin folder. It does not seem to look in the GAC. Any way I can fix that?

Your solution seems to have worked for others with the same question. There could be other issues with Crystal Reports installation on my computer.

Thanks. That was my first idea as well, but it resulted in a compilation error.

correct.. I can use this on my page. Hope it will stand forever..
