ASP.NET and shared assemblies

[Invalidlastname]

Hi,
We developed some assemblies which use EnterpriseServi ces queued components.
In order to use EnterpriseServi ces, these assemblies need to be installed
into GAC. I used the pre-build and post-build events to automate GAC
installation processes and the asp.net application has "copy to local" set
to false for the references of these shared assemblies.

However, every time we made the changes to the shared assemblies, we had to
restart the IIS in order to force the asp.net to use the new version of the
shared assemblies. If we did not restart the IIS, the asp.net will continue
to use the older version of the shared assemblies. I believe the reason of
recycling the IIS is actually to recycle the AppDomain so the ASP.NET will
bind to the most recent version of the shared assemblies. I know by changing
the web.config will recycle the AppDomain too, but since the web.config is
bound to the SourceSafe, by default it is read-only, and we don't want to
modify it for every changes made to the shared assemblies.

I believe this is a very common issue for ASP.NET development using shared
assemblies. There must be a better setup for this kind of the development.
Any helps will be appreciated

Hello,

How did you add the reference to the web application? Based on my test, the
web application will try to find the latest version of the referenced
assembly. (I added the reference by browsing to the classlibrary file and
set "copy local" to false.

Luke,
The referenced projects, shared assemblies, are in the same solution as
asp.net project. The references were added from Add Reference dialog box >
Projects tab. The "copy local" was set to "false" for the references to the
shared assemblies and to "true" for the references to private assemblies.

ILN,

That article is not entirely accurate. As long as you don't make a change
that causes the assembly hash value to change, you can update a new version
of the assembly in the GAC and the ASP.NET application will automatically
use the new version without changing anything. (It should be noted that
you do still have to reload the app domain.)

What changes the hash value? If you change the assembly name, the major or
minor version, the public key token, or the culture, the hash value will
change. As long as you don't modify any one of these, you would use the
following procedure to update the assembly in the GAC.

1. Run sn to create a new verification entry for the new version. Do that
as
follows:

sn -Vr <assembly>

2. Run Gacutil to reinstall the assembly as follows:

gacutil /nologo /if <assembly>

Once you do that, simply open the web.config, add a new blank line, and
save the web.config. That will force a reload of the app domain and your
application will use the new assembly.

If you have changed the hash value by changing one of the above, the
easiest way to force your application to use the new version in cases where
you can't redirect the assembly binding in a configuration file is to use a
publisher policy assembly. Most people will say that you should use a
publisher policy file, but that's not entirely accurate. The publisher
policy file is used to create the publisher policy assembly, and it's
actually the publisher policy assembly that redirects the binding.

Here is an example of doing this. In this example, my assembly is called
jcGAC.dll and I am changing the version number from 1.0.0.0 to 2.0.0.0.

1. Change code in version 1.0.0.0 of the assembly.

2. Change version number in assemblyinfo.cs to reflect new version.

3. Rebuild assembly.

4. Create publisher policy file in any text editor. You will need to
replace "<public_ke y>" with the public key for your version 1.0 assembly.

<configuratio n>
<runtime>
<assemblyBindin g xmlns="urn:sche mas-microsoft-com:asm.v1">
<dependentAssem bly>

5. Use al to create the publisher policy assembly. The publisher policy
assembly MUST have the following file format:
policy.major_ve r.minor_ver.ass embly.dll

The major and minor version shown here would be the major and minor
versions for your original version, not the updated new version. Below is
an example of the command entered to create the publisher policy assembly
for my assembly jcGAC.dll using the keyfile jcgac.snk. Note that the
publisher policy file in created in step 4 was saved as pub.config.

al /link:pub.config /out:policy.1.0. jcGAC.dll /keyfile:jcgac.s nk
6. Install publisher policy assembly into the GAC.

gacutil /i policy.2.0.jcGA C.dll

7. Install version 2.0.0.0 of your assembly into the GAC.

gacutil /i jcGAC.dll

8. Restart the app domains by either saving a change to the machine.config
or by resetting IIS.

9. Run the ASP.NET app.

After taking these steps, any ASP.NET application that originally
referenced version 1.0.0.0 will now bind to version 2.0.0.0.
Assembly binding is a fairly complex subject, but I hope that this helps
explain a bit.

Hi Jim,
Greatly thanks for the excellent details you provided. However, back to my
original question about how to setup the ASP.NET development environment for
using shared assemblies. Please correct me if I am wrong, it seems to me
that we need to add a post-build event to restart the IIS, or "touch" the
web.config for every changes made to the shared assembly projects ( in order
to reload the AppDomain).

I believe developers would appreciate if Microsoft can provide some
guidelines for developing ASP.NET applications with shared assemblies
scenarios. Actually the only reason we need to have shared assemblies is we
are using queued components from EnterpriseServi ce namespace.

ILN,

That article is not entirely accurate. As long as you don't make a change
that causes the assembly hash value to change, you can update a new version of the assembly in the GAC and the ASP.NET application will automatically
use the new version without changing anything. (It should be noted that
you do still have to reload the app domain.)

What changes the hash value? If you change the assembly name, the major or minor version, the public key token, or the culture, the hash value will
change. As long as you don't modify any one of these, you would use the
following procedure to update the assembly in the GAC.

1. Run sn to create a new verification entry for the new version. Do that as
follows:

sn -Vr <assembly>

2. Run Gacutil to reinstall the assembly as follows:

gacutil /nologo /if <assembly>

Once you do that, simply open the web.config, add a new blank line, and
save the web.config. That will force a reload of the app domain and your
application will use the new assembly.

If you have changed the hash value by changing one of the above, the
easiest way to force your application to use the new version in cases where you can't redirect the assembly binding in a configuration file is to use a publisher policy assembly. Most people will say that you should use a
publisher policy file, but that's not entirely accurate. The publisher
policy file is used to create the publisher policy assembly, and it's
actually the publisher policy assembly that redirects the binding.

Here is an example of doing this. In this example, my assembly is called
jcGAC.dll and I am changing the version number from 1.0.0.0 to 2.0.0.0.

1. Change code in version 1.0.0.0 of the assembly.

2. Change version number in assemblyinfo.cs to reflect new version.

3. Rebuild assembly.

4. Create publisher policy file in any text editor. You will need to
replace "<public_ke y>" with the public key for your version 1.0 assembly.

<configuratio n>
<runtime>
<assemblyBindin g xmlns="urn:sche mas-microsoft-com:asm.v1">
<dependentAssem bly>
<assemblyIdenti ty name="jcGAC"
publicKeyToken= "<public_ke y>"
culture="neutra l" />
<bindingRedirec t oldVersion="1.0 .0.0"
newVersion="2.0 .0.0"/>
</dependentAssemb ly>
</assemblyBinding >
</runtime>
</configuration>

5. Use al to create the publisher policy assembly. The publisher policy
assembly MUST have the following file format:
policy.major_ve r.minor_ver.ass embly.dll

The major and minor version shown here would be the major and minor
versions for your original version, not the updated new version. Below is
an example of the command entered to create the publisher policy assembly
for my assembly jcGAC.dll using the keyfile jcgac.snk. Note that the
publisher policy file in created in step 4 was saved as pub.config.

al /link:pub.config /out:policy.1.0. jcGAC.dll /keyfile:jcgac.s nk
6. Install publisher policy assembly into the GAC.

gacutil /i policy.2.0.jcGA C.dll

7. Install version 2.0.0.0 of your assembly into the GAC.

gacutil /i jcGAC.dll

8. Restart the app domains by either saving a change to the machine.config or by resetting IIS.

9. Run the ASP.NET app.

After taking these steps, any ASP.NET application that originally
referenced version 1.0.0.0 will now bind to version 2.0.0.0.
Assembly binding is a fairly complex subject, but I hope that this helps
explain a bit.

ILN,

Yes, you would have to reload the app domain. ASP.NET is written
explicitly so that it doesn't rebind to assemblies directly on each need.
If it had to do that, it would cause a critical bottleneck.

The first thing that happens in the binding order is that the CLR says,
"Have I bound to this assembly already?" If the answer is Yes, it simply
uses the previous binding.

Hi Jim,
Greatly thanks for the excellent details you provided. However, back to my
original question about how to setup the ASP.NET development environment forusing shared assemblies. Please correct me if I am wrong, it seems to me
that we need to add a post-build event to restart the IIS, or "touch" the
web.config for every changes made to the shared assembly projects ( in orderto reload the AppDomain).

I believe developers would appreciate if Microsoft can provide some
guidelines for developing ASP.NET applications with shared assemblies
scenarios. Actually the only reason we need to have shared assemblies is we
are using queued components from EnterpriseServi ce namespace.

"Jim Cheshire [MSFT]" <ja******@onlin e.microsoft.com > wrote in message
news:Z$******* *******@cpmsftn gxa06.phx.gbl.. .

ILN,

That article is not entirely accurate. As long as you don't make a change that causes the assembly hash value to change, you can update a new

version

of the assembly in the GAC and the ASP.NET application will automatically
use the new version without changing anything. (It should be noted that
you do still have to reload the app domain.)

What changes the hash value? If you change the assembly name, the major

or

minor version, the public key token, or the culture, the hash value will
change. As long as you don't modify any one of these, you would use the
following procedure to update the assembly in the GAC.

1. Run sn to create a new verification entry for the new version. Do

that

as
follows:

sn -Vr <assembly>

2. Run Gacutil to reinstall the assembly as follows:

gacutil /nologo /if <assembly>

Once you do that, simply open the web.config, add a new blank line, and
save the web.config. That will force a reload of the app domain and your
application will use the new assembly.

If you have changed the hash value by changing one of the above, the
easiest way to force your application to use the new version in cases

where

you can't redirect the assembly binding in a configuration file is to use

a

publisher policy assembly. Most people will say that you should use a
publisher policy file, but that's not entirely accurate. The publisher
policy file is used to create the publisher policy assembly, and it's
actually the publisher policy assembly that redirects the binding.

Here is an example of doing this. In this example, my assembly is called
jcGAC.dll and I am changing the version number from 1.0.0.0 to 2.0.0.0.

1. Change code in version 1.0.0.0 of the assembly.

2. Change version number in assemblyinfo.cs to reflect new version.

3. Rebuild assembly.

4. Create publisher policy file in any text editor. You will need to
replace "<public_ke y>" with the public key for your version 1.0 assembly.

<configuratio n>
<runtime>
<assemblyBindin g xmlns="urn:sche mas-microsoft-com:asm.v1">
<dependentAssem bly>
<assemblyIdenti ty name="jcGAC"
publicKeyToken= "<public_ke y>"
culture="neutra l" />
<bindingRedirec t oldVersion="1.0 .0.0"
newVersion="2.0 .0.0"/>
</dependentAssemb ly>
</assemblyBinding >
</runtime>
</configuration>

5. Use al to create the publisher policy assembly. The publisher policy assembly MUST have the following file format:
policy.major_ve r.minor_ver.ass embly.dll

The major and minor version shown here would be the major and minor
versions for your original version, not the updated new version. Below is an example of the command entered to create the publisher policy assembly
for my assembly jcGAC.dll using the keyfile jcgac.snk. Note that the
publisher policy file in created in step 4 was saved as pub.config.

al /link:pub.config /out:policy.1.0. jcGAC.dll /keyfile:jcgac.s nk
6. Install publisher policy assembly into the GAC.

gacutil /i policy.2.0.jcGA C.dll

7. Install version 2.0.0.0 of your assembly into the GAC.

gacutil /i jcGAC.dll

8. Restart the app domains by either saving a change to the

machine.conf ig

or by resetting IIS.

9. Run the ASP.NET app.

After taking these steps, any ASP.NET application that originally
referenced version 1.0.0.0 will now bind to version 2.0.0.0.
Assembly binding is a fairly complex subject, but I hope that this helps
explain a bit.

ILN,

You are very welcome. That's my day job. :) I'm glad the info helped.
We want developers to understand as much as possible about the internal
implementation of ASP.NET.

Here's a good article that might help as well:

Jim,
Again, thank you for giving me such detailed explanations. It is really
helpful.

ILN,

Yes, you would have to reload the app domain. ASP.NET is written
explicitly so that it doesn't rebind to assemblies directly on each need.
If it had to do that, it would cause a critical bottleneck.

The first thing that happens in the binding order is that the CLR says,
"Have I bound to this assembly already?" If the answer is Yes, it simply
uses the previous binding.
