I have a .net 2.0 webservices using .net 2.0 librarys (dll). My config uses assembly binding to use the latest builds,Now the .net2.0 will be migrated to .net 4.0, does this mean i have to move my service to 4.0 as well?
Thanks

running web app under clr 4.0 which can be done by changing IIS applicaton pool for the site to use .net 4.0.

Samples for grpc.core server implementation in .NET framework 4.7
We are planning to migrate from .NET framework to .NET core (.NET6). As part of this migration, we want to first move to grpc.core from WCF. When we searched for sample service implementation using grpc.core in .NET frameowrk 4.7, we ended up getting nothing. All the results were pointed to the implementation using grpcdotent in dotnet6.
Here is a grpc.core server and client hello world example
This example's server project targets .NET Core 3.1 but you can essentially use the same code/approach for .NET 4.7
We have old .net 1.1 project that is using a third party component. Aparently that component is not working properly with new requirements, and there is no support from the provider. Provider proposed to use new component that is working properly. The problem is that this component requires .net 2.0.
The project is big and it will be costly to move this project to 2.0.
What other alternatives we can have? How 1.1 assembly can call 2.0 assembly?
.NET 1.1 can't load .NET 2.0 assemblies, because the internal format changed. Your app will basically think that the assembly isn't a .NET assembly.
Long term, it would be a good idea to update your application to use .NET 2.0 (if not something newer, since there are multiple versions of .NET since 2.0 now). However, if that is not an option, you could create a .config file for your executable, and tell the CLR to always use .NET 2.0 when running your app. This should allow for the .NET 2.0 assembly to load, however any breaking changes between .NET 1.1 and 2.0 that your app makes use of will cause errors.
I am having a Web Application with build target as .Net Framework 4.0.
I want to interact with the Sharepoint Object Model API's but it gives a framework 4.0 runtime does not supports Sharepoint.dll error.
Is their any tweak such that I can use Sharepoint 2010 with .Net Framework4.0.
Note: I cannnot change the build target of the web app to any other framework as I am using some exclusive features of .net 4.0 in my application.
Sorry you probably will have no luck:
There appears to be some confusion
around whether or not ASP.NET 4 is
supported for both MOSS and SharePoint
2010 - in short, the answer is that it
is not currently supported in either
product.
Whilst it is possible to use ASP.NET
3.5 in MOSS by making some modifications to the SharePoint site
web.config (instructions for doing
that in MOSS here; SP2010 uses 3.5 by
default), this is unfortunately not
the case with version 4.
The reason? ASP.NET 4 uses a new
version of the Common Language Runtime
(CLR). Whilst .NET 2.0, 3.0 and 3.5
all used version 2.0 of the CLR, .NET
4 uses version 4. I'm not entirely
sure what happened to version 3. There
is a decent post on stack overflow
with further details.
from SharePoint 2010 and .NET 4: confused?
Maybe .NET 4.0 Support will be added in a future update (SP1?) who knows...
Unfortunately, .Net 2.0 to 3.5 use a different application pool type from .Net 4.0; Mixing in the same app pool is not going to work.
What features of .Net 4.0 are you using, and perhaps the community can help you with a 3.5 solution?
What exactly does the .NET 4.0 runtime do if a .NET 4.0 executable contains a reference to a .NET 2.0 assembly?
Is the .NET 2.0 assembly run with the .NET 4.0 runtime (in other words, .NET 4.0 must be 100% API-compatible to .NET 2.0) or does the process somehow host the .NET 2.0 runtime and some magic happens to make the .NET 2.0 types transparently accessible to my .NET 4.0-based code?
They say it should work fine. Check out this.
I am creating a diagnostic page for ASP.NET and would like to programatically detect if ASP.NET 3.5 has been installed on the server. Any ideas on how to best do this?
System.Environment.Version gives you the CLR version.
For ASP.NET 2.0, 3.0 and 3.5 it will return the same CLR version: 2.0.50727.3053
As for ASP.NET 4.0 the CLR version will change to 4.*
