this link installed all both runtime and sdk 3.1.100 preview
https://aur.archlinux.org/dotnet-core-preview.git
this link installed 3.0.0 runtime
https://aur.archlinux.org/dotnet-core-bin.git
this link installed 3.0.100 sdk
https://aur.archlinux.org/dotnet-sdk-bin.git

after installation i faced issue

project file not found

resolved by adding two environment variable to

~/.bashrc

using the command : sudo nano ~/.bashrc

after that file look like this

#
# ~/.bashrc
#

# If not running interactively, don't do anything
[[ $- != *i* ]] && return

alias ls='ls --color=auto'
PS1='[\u@\h \W]\$ '

export DOTNET_ROOT=/opt/dotnet/

export MSBuildSDKsPath=/opt/dotnet/sdk/3.1.100-preview3-014645/Sdks/

with this project not found exception was resolved but i faced new exception that

Sdk path not found

for that there is a file with path

/usr/bin/dotnet

that contained the following data

#!/bin/sh

export DOTNET_ROOT=/opt/dotnet
exec /opt/dotnet/dotnet "$@"

# vim: ts=2 sw=2 et:

i deleted this file and add a symlink to dotnet file path to /opt/dotnet/dotnet with following command

sudo ln -s /opt/dotnet/dotnet /usr/bin/dotnet

everything worked fine after words at-least my webapi worked fine
