I have a visual studio install setup project in which I want to specify that pre-requisite is .Net 2.0
When I click properties-> pre-requisite
it shows only .Net framework 3.5 / client profile and .Net framework 4.0/client profile and other components but not .Net 2.0
The second part is will the installer fail if pre-reqs are not met or install them automatically ?
Thanks,
If you look in the properties for the solution you can select which version of the .NET framework you use. Note this is for the non Express versions only.

Furthermore Microsoft keeps itself in business by only making VS backwards but not forwards compatible with future .NEzt versions.
To create an installer you needmtomcreatemamDeployment project and specify the dependendcies.

Looks like when I run TeeChartNET2015EVAL_4.1.2015.12166.exe, it installs version of TeeChart.dll built on framework 4.5 only. I need to do the evaluation with the dll built with framework 3.5 (because I have to integrate to an already existing application based on Framework 3.5). Is there any way I can get the evaluation dll for Framework 3.5?
Thanks
When running the installer you need to choose which environments do you want the assemblies for. If you choose Visual Studio 2008 this will install .NET Framework 3.5 assemblies as this is the default framework supported by this environment.
Whatever I do for several days now, Web Developer 2010 Express does not see 4.0 NET Framework. If to right click on solution properties in the Application – Target Framework it lists 2.0, 3.0 and 3.5, which are NOT installed on my computer but 4.0 which is actually installed. I tried to clean all using dotnetfx_cleanup_tool, reinstalled 4.0 client and full several times, copied reference assemblies to different folders and so on but WDE still does not see it.
I also have SDK for Windows 7 and .NET Framework 4 installed.
Where and how does it find frameworks, does in scan registry or some config file?
To target .NET 2.0/3.0/3.5, you have to install .NET 3.5.
And Web Develoepr requires full profile, not client profile.
I will try to explain this as clear as I can
I want to fully understand how MSBuild multitargeting works.
I have read several articles from Microsoft and I think I understand the basic but I want to be sure I am not missing anything.
According to Microsoft:
By using Visual Studio, you can compile an application to run on any one of several versions of the .NET Framework. For example, you can compile an application to run on the .NET Framework version 2.0, and compile the same application to run on the .NET Framework version 4. The ability to compile to more than one framework is named multitargeting.
Visual Studio runs under the most current version of the .NET Framework that is installed on the development computer.

So do this mean that Visual Studio always calls MSBuild from the latest framework installed? assuming Visual Studio 2010 is installed, it will always call: %WINDIR%\Microsoft.NET\Framework\v4.0.30319\MsBuild.exe when building any project targettting any .Net Framework version right???
If yes, then the ability to target old .Net Framewrok versions is based on the ToolsVersion and/or TargetFrameworkVersion properties right???
If yes again, it would mean that just installing the latest framework (and also the older frameworks but not installing visual studio) in my Continuous Integration box, I could point to build always any solution to: %WINDIR%\Microsoft.NET\Framework\v4.0.30319\MsBuild.exe and just specify the ToolsVersion argument (if required, since each project can have its own target version specified in the TargetFrameworkVersion which it would cause to target an older .Net Framework version).
Following this I think my CI box would be building like Visual Studio does. Am I right? What am I missing? Is there a way to be completely sure?
I did a quick test, and I think it works :p the projects are being built according to the .Net Framework specified but like I said I want to be sure I am not missing anything.
Any thoughts?
BTW:
The simple reason to want to do that is because I have several custom MSBuild scripts that are reusable accross projects, but some of the functionality in these scripts require MSBuild 4.0 and also I have several MSBuild tasks built on top of the framework 4.0 so if I have for example a solution targetting the Framework 2.0 and I try to build it using: %WINDIR%\Microsoft.NET\Framework\v2.0.50727\MsBuild.exe I get MSBuild errors trying to load my custom targets
Yes, you've got it mostly correct. Calling MSBuild from the 4.0 directory will do the correct thing against previous versions. They only thing I wanted to add was that 3.5 must be on the box to actually build projects targeting 2.0, 3.0 and 3.5.
This page here: http://msdn.microsoft.com/en-us/library/bb822049.aspx calls out the what versions Windows comes with what version of the framework pre-installed.
Fairly self-explanatory. I have recently installed .NET framework 4 and VS2010 but I want to compile my 3.5 projects using 3.5 as 4 has not yet been installed on our production servers and I get "This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded." if I try
All project types have the target framework dropdown greyed out
Make sure that your registry keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\OnlyUseLatestCLR
and
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\OnlyUseLatestCLR
are set to 0 (not 1).
This fixed it for me since applications like VS2008 are no longer forced to use .NET 4.0 runtime. I had previously set these registry keys to allow Powershell run inder .NET 4.0, however, a config file should be used for that instead.
This has something to do with .NET 2.0 assemblies (i.e. mscorlib) being removed from GAC.
I managed to fix this by first uninstalling .NET framework 3.5 and 4.0 from my Windows 7 using .NET framework cleanup tool:
http://blogs.msdn.com/b/astebner/archive/2008/08/28/8904493.aspx
And then reinstalling both frameworks (first 3.5, then 4.0) from the web. Now the drop-down has options again in VS2008 and I can multi-target 3.5 framework from VS2010.
Using VS 2008
I created a setup file for my Project, I run the setup file in my system, and My Project is working fine.
If I install my project to another system, is asking .Net Framework 3.5 at the setup time.
.Net Framework 3.5 is needed for installing my Project?
Before i installing my project, i install the .net framework 3.5, It taking to much time to setup?
How to solve this? or any other way to create a Project setup ?
Can any one help to solve my setup problem.
What you need to do is right click on the setup project in the SolutionExplorer and select the Properties menu option. You can then click on the Prerequisites button. This allows you to control what your setup program needs/wants in order to install your code.
If you don't need .NET 3.5 then just unselect it. This is just one more annoying thing that VS2008 does, you select .NET 2.0 as your target framework but it leaves .NET 3.5 as a pre-req.
If it is important for you that your program does ot require .NET 3.5, you can set up your project to target .NET 2.0. The the setup project will also see this, and (hopefully) remove the dependency when you update it.
If your project is VB.NET, you can set the Target Framework version here:
Project Properties -> Compile -> Advanced Compile Options...
If Your project is C#, it is here:
Project Properties -> Application
If you do this, of course you will not have available any .NET 3 specific functionality.
Do you rely on .net 35 features in your code. If not you can recompile with the project settings targetting .net 3.0 or 2.0.
The .NET 3.5 framework has two different installers to choose from: the bootstrapper and the full package.
The bootstrapper installer is small in size (2.7 MB). It's small because it downloads the required files from the internet when executed on the target machine. Depending upon the target's network bandwidth, it may take a long time to run.
The full package installer is large (237 MB), and does not require an internet connection to run.
If you are currently using the bootstrapper installer, you should try downloading the full package installer and running that on the target machines.
(That is, if you actually need .NET 3.5)
You can select either installer from here.
