Proxygen Error with .NET 4.0 using MyCSharpDemoCalc

[sselvia]

I expanded the VS project and used VS 2010 to build the project
using .NET Framework 4 as the target framework. If I use 3.5
framework the proxygen works. I need to use a 4.0 framework assembly
from within my DLL.

Is there a configuration file that I need to set 4.0 compatibility?

Create proxygen.exe.config with the correct full supportedRuntime
version and place it next to proxygen.exe

<configuration>
<startup>
<supportedRuntime version="v4.0.30319"/>
</startup>
</configuration>

make sure your CLR build version "30319" is what you put in the config file.

I added the proxygen.exe.config as I found in another post, still the
same results:

<configuration>
<startup>
<supportRuntime version="4.0"/>
</startup>
</configuration>

Why would the proxygen be using this config when I told it via the
config to support the 4.0 runtime:

LOG: Using machine configuration file from C:\Windows\Microsoft.NET
\Framework64\ v2.0.50727\config\machine.config

[Pavel Šavara]

try to add build version too. I think it falls back to it's natural
version if it could not find strong match. Or maybe you could add star
like this.
<supportRuntime version="4.0.*"/>

[sselvia]

I did make the change:

<configuration>
<startup>
<supportRuntime version="v4.0.30319"/>
</startup>
</configuration>

I do have the following folder:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319

But I'm still getting the same error and for some reason it is not
using the v4... config. Is there a registry setting that needs to be
changed that your code is looking at?

I tried the 4.0.* and it still did not work, anymore ideas?

I was hoping you had another option or idea on the issue? Is it an
issue with proxygen or just a registry setting?

[Pavel Šavara]

it works for me, so I have no further idea. Maybe your machine config
is configured wrongly.
Or you added some dll which is 32 bit and you are running 64 bit proxygen.
Actually, did you compiled the MyCSharpDemoCalc.dll to x86 or MSIL ?

Thank you for you help thus far, over the weekend I did a new install
of Vista x64 with Visual Studio 2010 and I get the same results that I
have at work. The only difference between the two is the OS, at work
I'm using Windows 7 x64. The MyCSharpDemoCalc VS project in both
cases had to be converted to a VS 2010 and in both cases there was no
problem. I tried to generate the proxies with code compiled in x32,
x64, and Any CPU and in all cases I get the same results when I have
the .NET Framework 4 selected.

If this was just on one machine I would agree that there would be a
problem with the machine config, however on two different machines
with a fresh install of VS 2010, I now suspsect there really is an
issue with the proxygen application.

Is there any other logging that I can turn on? I would be glad to test
any code fixes if you would supply them to give you more information
to the problem.

Thanks again for you time on this issue.

Pavel, I figured it out after downloading the source and debugging the
jni4net.proxygen.10 project. When I walked through the code I found
the exception was in the LoadAssemblies() method in the
Repository.Helpers.cs. I then re-compiled the project with the
jni4net.n.10 and jni4net.proxygen.10 project both targeting the .NET
Framework 4 and it worked. I then noticed the config file that was
generated when I ran the code. Once I put in the sku entry the
myCSharpDemoCalc worked when compiled to target the 4.0 framework. I
was also able to build my test project.

<?xml version="1.0"?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
</configuration>

Hi Scott,

I'm glad to hear it :-)

I realized that I could add CLR 4.0 as preferred runtime while
preserving ability to run proxygen on CLR 2.0.

<?xml version="1.0" encoding="utf-8" ?>

<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>

<supportedRuntime version="v2.0.50727"/>
</startup>
</configuration>

I added this proxygen.exe.config into binary distribution for next version.
Preview is here:
http://www.ane-kolin.cz/zamboch/jni4net-0.8.5.0-snapshot20110707-bin.zip

I also added new sample runtimeSelection, which could help people to
learn about their runtime versions.
Finally jni4net runtime and proxygen are now dumping runtime versions
when running setup in verbose mode.

Feedback appreciated, thanks!
Pavel

[Scott Selvia]

Just got back to it, I'll work with the new code. Thanks
